1.7 Safety

1.7.1 Safety notices

Mortal danger - Hazardous voltage

• Electrical equipment operation means that some parts can be under dangerous voltage. Therefore all parts under voltage must be covered! This basically applies to all models, though 40 V models according to SELV can not generate hazardous DC voltage!

• All work on connections must be carried out under zero voltage (output not connected to

load) and may only be performed by qualied and informed persons. Improper actions

can cause fatal injury as well as serious material damage!

• Never touch cables or connectors directly after unplugging from mains supply as the danger of electric shock remains!

• Never touch the contacts on DC output terminal directly after switching o󰀨 the DC

output, because there still can dangerous voltage present, sinking more or less slowly depending on the load! There also can be dangerous potential between negative DC output to PE or positive DC output to PE due to charged X capacitors.

• Always follow 5 safety rules when working with electric devices:

• Disconnect completely

• Secure against reconnection

• Verify that the system is dead

• Carry out earthing and short-circuiting

• Provide protection from adjacent live parts

PS 9000 3U Series

• The equipment must only be used as intended

• The equipment is only approved for use within the connection limits stated on the product label.

• Do not insert any object, particularly metallic, through the ventilator slots

• Avoid any use of liquids near the equipment. Protect the device from wet, damp and conden-

sation.

• For power supplies and battery chargers: do not connect users, particularly low resistance, to devices under power; sparking may occur which can cause burns as well as damage to the equipment and to the user.

• For electronic loads: do not connect power sources to equipment under power, sparking may occur which can cause burns as well as damage to the equipment and to the source.

• ESD regulations must be applied when plugging interface cards or modules into the relative slot

• Interface cards or modules may only be attached or removed after the device is switched o󰀨.

It isn’t necessary to open the device.

• Do not connect external power sources with reversed polarity to DC input or outputs! The equipment will be damaged.

• For power supply devices: avoid where possible connecting external power sources to the DC output, and never those that can generate a higher voltage than the nominal voltage of the device.

• For electronic loads: do not connect a power source to the DC input which can generate a voltage more than 120% of the nominal input voltage of the load. The equipment isn’t protected against over voltage and may be irreparably damaged.

• Never insert a network cable which is connected to Ethernet or its components into the master-slave socket on the back side of the device!

• Always congure the various protecting features against overvoltage overpower etc. for sensitive loads to what the currently used application requires

(1 Related to the nominal values, the accuracy denes the maximum deviation between an adjusted values and the true (actual) value. Example: a 80 V model has min. 0.1% voltage accuracy, that is 80 mV. When adjusting the voltage to 5 V, the actual value is allowed to di󰀨er max. 80 mV, which means it might be between 4.92 V and 5.08 V.

1.9 Construction and function

1.9.1 General description

The electronic high performance power supplies of the PS 9000 3U series are especially suitable for test systems and industrial controls due to their compact construction in a 19” enclosure with 3 height units (3U).

For remote control using a PC or PLC the devices are provided as standard with an USB port and an Ethernet port on the back side as well as an analog interface. All interfaces are galvanically isolated up to 1500 V DC.

In addition, the devices o󰀨er as standard the possibility for parallel connection in Share bus operation for constant current sharing. Operating in this way allows up to 16 units to be combined to a single system with a total power of up to 240 kW.

All models are controlled by microprocessors. These enable an exact and fast measurement and display of actual values.

1.9.6 The control panel (HMI)

The HMI (Human Machine Interface) consists of a color TFT display, two rotary knobs with button function and six pushbuttons.

1.9.6.1 Display

The graphic display is divided into a number of areas. In normal operation the upper part (⅔) is used to show actual and set values and thelower part (⅓) to display status information:

Actual voltage + set value

Regulation mode CV

Actual current + set value

Regulation mode CC

Actual power +

set value

Regulation

mode CP

Various status displays (symbols, strings) and quick menu

• Actual / set values area (blue / green / red)

In normal operation the DC output values (large numbers) and set values (small numbers) for voltage, current and power.

While the DC output is switched on, the actual regulation mode CV, CC or CP is displayed above to the corresponding set value, as shown in the gure above with example “CV”.

The set values can be adjusted by rotating the knobs below the display, whereas pushing the knobs are used to select the digit to be changed. Logically, the values are increased by clockwise turning and decreased by anti-clockwise turning. The current assignment of set a value to a knob is indicated by the corresponding set value being displayed in inverted form and also by the knob depiction in the status area showing the physical sign (U, I,P). In case these are not shown, the values can’t be adjusted manually, like in HMI lock or remote control.

General display and settings ranges:

• Area for assigning the rotary knobs

The two rotary knobs below the display screen can be assigned to various functions. The status area in the display area depicts the actual assignments. After the device start and in the main screen the default assignment is voltage (left-hand knob) and current (right-hand knob):

These two values can then be adjusted manually. The decimal place to adjust is underlined, the currently selected value is displayed in inverted format:

. There are following possible assignments, whereas the right-hand knob

remains assigned to the set value of current:

U I U P

Left rotary knob: voltage

Right rotary knob: current

The other set values can’t be adjusted directly, until the assignment is changed. This is done using the “arrow down” button, as depicted by this symbol next to the corresponding knob depiction:

. With this being shown, the momentary assignment is to current and it can be changed to power.

1.9.6.2 Rotary knobs

As long as the device is in manual operation, the two rotary knobs are used to adjust set values, as well as setting the parameters in the settings menu . For a detailed description of the individual functions see section „3.4 Manual operation“ on page 48. Both rotary knobs have an additional pushbutton function to select the decimal position of the value to be set. In this way the set current value for a device with, for example, nominal 510 A can be adjusted in various increments of 10 A or 0.1 A etc. Also see 1.9.6.4.

Left rotary knob: voltage Right rotary knob: power

1.9.6.3 Button function of the rotary knobs

The rotary knobs also have a pushbutton function which is used in all menu options for value adjustment to move the cursor by rotation as shown:

1.9.7 USB port

The USB-B port on the back side of the device is provided for communication with the device and for rmware updates. The included USB cable can be used to connect the device to a PC (USB 2.0, USB 3.0). The driver is delivered on the included USB stick or is available as download and installs a virtual COM port. Details for remote control can be found in external documentation, such as a general programming guide, on the included USB stick or on the web site of the manufacturer.

The device can be addressed via the USB port either using the international standard ModBus RTU protocol or by SCPI language. The device recognises the message protocol used automatically.

If remote control is in operation the USB port has no priority over either the analog interface or the Ethernet interface and can, therefore, only be used alternatively to these. However, monitoring is always available.

1.9.8 Ethernet port

The Ethernet port on the back side of the device is provided for communication with the device in terms of remote control or monitoring. The user has basically two options of access:

1. A website (HTTP, port 80) which is accessible in a standard browser under the IP or the host name given for the device. This website o󰀨ers to conguration page for network parameters, as well as a input box for SCPI commands to control the device remotely by manually entering commands.

2. TCP/IP access via a freely selectable port (except 80 and other reserved ports). The standard port for this device is 5025. Via TCP/IP and this port, communication to the device can be established in most of the common programming languages.

Using the Ethernet port, the device can either be controlled by commands from SCPI or ModBus RTU protocol, while automatically detecting the type of message.

The network setup can be done manually or by DHCP. The transmission speed is set to “Auto negotiation” and means it can use 10MBit/s or 100MBit/s. 1GB/s isn’t supported. Duplex mode is always full duplex.

If remote control is in operation the Ethernet port has no priority over either the analog interface or the USB interface and can, therefore, only be used alternatively to these. However, monitoring is always available.

1.9.9 Analog interface

This 15 pole Sub-D socket on the back side of the device is provided for remote control of the device via analog signals or switching conditions.

If remote control is in operation this analog interface can only be used alternately to the digital interface. However, monitoring is always available.

The input voltage range of the set values and the output voltage range of the monitor val-

ues, as well as reference voltage level can be switched in the settings menu of the device between 0-5 V and 0-10 V, in each case for 0-100%.

1.9.10 Share Bus connection

The 2 pole Phoenix socket labeled “Share” on the back side of the device is provided for connection to equally named sockets on compatible power supplies series to achieve a balanced load current distribution during parallel connection of up to 16 units. For more information skip to „3.9.1. Parallel operation in Share bus mode“. There is furthermore to option to create a two-quadrants operation system with compatible electronic loads. For this, refer to „3.9.4. Two quadrants operation (2QO)“.

1.9.11 Sense connector (remote sensing)

If the output voltage has to be dependant on the consumer location rather than the DC output of the power supply, then the input “Sense” can be connected to the consumer where the DC connection is made. This compensates, up to a certain limit, the voltage di󰀨erence between the power supply output and the consumer, which is caused by the high current through the load cables. The maximum possible compensation is given in the technical data.

In order to ensure safety and to comply to international directives, insulation of high voltage

models, i. e. such with a nominal voltage of 500 V or higher, is ensured by using only the two outer pins of the 4-pole terminal. The inner two pins, marked with NC, must remain unconnected.

1.9.12 GPIB port (optional)

The optional GPIB connector, which is available with option 3W, will replace the Ethernet connector of standard version devices. Option 3W then o󰀨ers a di󰀨erent three-way interface with GPIB, USB and analog interfaces.

The connection to a PC or other GPIB port is done with standard GPIB cables from stock, which can have straight or 90° connectors.

When using cable with 90° connectors, the USB port will be inaccessible.

2. Installation & commissioning

2.1 Transport and storage

2.1.1 Transport

• The handles on the front side of the device are not for carrying!

• Because of its weight, transport by hand should be avoided where possible. If unavoidable then

only the housing should be held and not on the exterior parts (handles, DC output terminal, rotary knobs).

• Do not transport when switched on or connected!

• When relocating the equipment use of the original packing is recommended

• The device should always be carried and mounted horizontally

• Use suitable safety clothing, especially safety shoes, when carrying the equipment, as due to

its weight a fall can have serious consequences.

2.1.2 Packaging

It is recommended to keep the complete transport packaging for the lifetime of the device for relocation or return

to the manufacturer for repair. Otherwise the packaging should be disposed of in an environmentally friendly way.

2.1.3 Storage

In case of long term storage of the equipment it is recommended to use the original packaging or similar. Storage must be in dry rooms, if possible in sealed packaging, to avoid corrosion, especially internal, through humidity.

2.2 Unpacking and visual check

After every transport, with or without packaging, or before commissioning, the equipment should be visually inspected for damage and completeness using the delivery note and/or parts list (see section „1.9.3. Scope of delivery“). An obviously damaged device (e.g. loose parts inside, damage outside) must under no circumstances be put in operation.

2.3 Installation

2.3.1 Safety procedures before installation and use

• The device may, according to model, have a considerable weight. Therefore the proposed location of the equipment (table, cabinet, shelf, 19” rack) must be able to support the weight without restriction.

• When using a 19” rack, rails suitable for the width of the housing and the weight of the device are to be used. (see „1.8.3. Specic technical data (400 V AC models)“)

• Before connecting to the mains ensure that the supply voltage is as shown on the product

label. Overvoltage on the AC supply can cause equipment damage.

PS 9000 3U Series

2.3.2 Preparation

Mains connection for the PS 9000 3U series is done via the included 5 pole plug on the back of the device. Wiring of the plug is at least 3 wire (L2+L3+PE) or, for some models, 4 wire (L1+L2+L3+PE) of suitable cross section and length. It’s allowed to wire the N conductor of a standard three-phase cable to the remaining input pin. For recommendations for cable cross section see „2.3.4. Connection to AC supply“.

Dimensioning of the DC wiring to the load/consumer has to reect the following:

• The cable cross section should always be specied for at least the maximum current of the device.

• Continuous operation at the approved limit generates heat which must be removed, as well as voltage loss which depends on cable length and heating. To compensate for these the cable cross section should be increased and the cable length reduced.

2.3.3 Installing the device

• Select the location for the device so that the connection to the load is as short as possible.

• Leave su󰀩cient space behind the equipment, minimum 30cm (1 ft), for ventilation.

A device in a 19” housing is designed to be installed in 19” racks or cabinets, which are either lockable or at least have closable doors. This is required to achieve a su󰀩cient protection against touching parts leading dangerous voltage.

The device can rest on rails or a shelf. When selecting those the depth of the device and its weight must be taken into account. The handles on the front are intended to help sliding it in or out of the cabinet. Slots on the front plate are provided for xing the device (xing screws not included).

Acceptable and unacceptable installation positions:

2.3.4 Connection to AC supply

• Connection to an AC mains supply may only be carried out by qualied personnel!

• Cable cross section must be suitable for the maximum input current of the device (see table

below)!

• Before plugging in the input plug ensure that the device is switched o󰀨 by its mains switch!

2.3.4.1 Models for 400 V

The device is delivered with a 5 pole AC plug. Depending on model, the plug is connected to a 2-phase or 3-phase AC supply, according to the labeling on the plug. Required are following phases:

Nominal power Phases Supply type

3.3 kw / 5 kW L2, L3, PE Two-phase

6.6 kW / 10 kW L1, L2, L3, PE Three-phase ≥15 kW L1, L2, L3, PE Three-phase

The PE conductor is imperative and must always be wired!

For the selection of a suitable cable cross section the rated AC current of the device and the cable length are decisive. Based on the connection of one single unit the table lists the maximum input current and recommended minimum cross section for each phase:

2.3.4.3 Connection variants

Depending on the max. output power of a certain model, it requires two or three phases of a three-phase AC supply. In case multiple units with 3.3 kW to 10 kW power rating are connected to the same AC supply point, it is recommended to take care for balanced current distribution on the three phases. See table in 2.3.4 for the max. phase currents.

The 15 kW models are an exception, because they already consume balanced current on all three phases they require. As long as only such models are installed, no unbalanced AC load is expected. Systems of 15 kW models mixed with 10 kW models (note: the 10 kW model PS 9040-510 3U is internally congured like a 15 kW) or models with lower power are not automatically balanced.

Suggestions to assign phases:

Single unit (3.3 kW / 5 kW)

Multiple units (3.3 kW / 5 kW) Multiple units (6,6 kW / 10 kW)

2.3.5 Connection to DC loads

• In the case of a device with a high nominal current and hence a thick and heavy DC connection cable it is necessary to take account of the weight of the cable and the strain imposed on the DC connection. Especially when mounted in a 19” cabinet or similar, where the cable hangs on the DC output, a strain reliever should be used.

• Connection to and operation with transformerless DC-AC inverters (for example solar inverters) is restricted, because the inverter can shift the potential of negative output (DC-) against PE (ground), which is generally limited to a specic level. See „1.8.3. Specic tech-

nical data (400 V AC models)“ or „1.8.4. Specic technical data (208 V AC models)“, item

“Insulation”

The DC load output is on the back side of the device and isn’t protected by a fuse. The cross section of the connection cable is determined by the current consumption, cable length and ambient temperature.

For cables up to 1.5 m (4.9 ft) and average ambient temperature up to 50°C (122°F), we recommend:

up to 30 A: 6 mm² up to 70 A: 16 mm² up to 90 A: 25 mm² up to 140 A: 50 mm² up to 170 A: 70 mm² up to 210 A: 95 mm² up to 340 A: 2x70 mm² up to 510 A: 2x120 mm²

per connection pole (multi-conductor, insulated, openly suspended). Single cables of, for example, 70 mm² may be replaced by e.g. 2x35 mm² etc. If the cables are long then the cross section must be increased to avoid voltage loss and overheating.

2.3.5.1 DC terminal types

The table below shows an overview of the various DC terminals. It is recommended that connection of load cables always utilises exible cables with ring lugs.

Type 1: Models up to 360 V output voltage Type 2: Models from 500 V output voltage

M8 bolt on a metal rail Recommendation: ring lug with a 8 mm hole

M6 bolt on a metal rail Recommendation: ring lug with a 6 mm hole

2.3.5.2 Cable lead and plastic cover

A plastic cover for contact protection is included for the DC terminal. It should always be installed. The cover for type 2 (see picture above) is xed to the connector itself, for type 1 to the back of the device. Furthermore the cover for type 1 has break outs so that the supply cable can be laid in various directions.

The connection angle and the required bending radius for the DC cable must be taken into account when planning the depth of the complete device, especially when installing in a 19” cabinet or similar. For type 2 connectors only a horizontal lead can be used to allow for installation of the cover.

Examples of the type 1 terminal:

• 90° up or down

• space saving in depth

• no bending radius

• horizontal lead

• space saving in height

• large bending radius

2.3.6 Connection of remote sensing

In order to compensate, to a certain degree, the voltage loss in a DC cable, the device provides the possibility to connect the remote sensing input “Sense” to the load. The device recognizes the remote sensing mode automatically and regulates the output voltage (only in CV operation) at the load rather than at its own DC output.

In the technical specications (see section „1.8.3. Specic technical data (400 V AC models)“) the level of maximum possible compensation is given. If that is insu󰀩cient, the cable cross section must be increased.

Both pins „NC“ of the Sense connector must not be wired!

• Remote sensing is only eective during constant voltage operation (CV) and for other regulation

modes the sense input should be disconnected, if possible, because connecting it generally increases the oscillation tendency.

• The cross section of the sense cables is noncritical. However, it should be increased with

increasing cable length. Recommendation: for cables up to 5 m (16.4 ft) use at least 0.5 mm²

• Sense cables should be twisted and laid close to the DC cables to damp oscillation. If necessary, an additional capacitor should be installed at the load/consumer to eliminate oscillation

• The sense cables must be connected + to + and - to - at the load, otherwise both systems may be damaged

2.3.7 Grounding of the DC output

Grounding one of the DC output poles is allowed. Doing so results in a potential shift of the other pole against PE. Because of insulation, there is a max. allowed potential shift of the DC output poles, which also depends on the

device model. Refer to the technical specications.

2.3.8 Connecting the “Share” bus

The “Share” connector on the back side is intended to balance the current of multiple units in parallel operation by balancing the output voltage in CV operation. Thus it’s recommended to use the Share bus in this operation mode. For further information about this mode of operation can be found in section „3.9.1. Parallel operation in Share bus mode“.

The Share bus furthermore can be used to connect the power supply to a compatible electronic load (see section „1.9.10. Share Bus connection“), in order to achieve a correct switchover between sink and source in the so-called two-quadrants operation.

For the connection of the share bus the following must be paid attention to:

• Connection is only permitted between compatible devices (see „1.9.10. Share Bus connection“ for details) and between a max. of 16 units

• When switching o󰀨 one or multiple units of a parallel system, because less power is required for an application, it’s recommended to remove the Share bus plug from the inactive units, because their Share bus port’s impedance could have a negative impact on the Share bus

• If a two-quadrants operation system has to be set up where multiple power supplies are connected to one electronic load unit or a group of electronic loads, all units should be connected via Share bus.

• The Share bus is referenced to DC minus. When building a series connection (where allowed, depending on model), the DC minus will shift its potential and so will the Share bus

2.3.9 Connecting the analog interface

The 15 pole connector (Type: Sub-D, D-Sub) on the rear side is an analog interface. To connect this to a controlling hardware (PC, electronic circuit), a standard plug is necessary (not included in the scope of delivery). It is generally advisable to switch the device completely o󰀨 before connecting or disconnecting this connector, but at least the DC output.

The analog interface is galvanically isolated from the device internally. Therefore do not connect any ground of the analog interface (AGND) to the DC minus output as this will cancel the galvanic isolation.

2.3.10 Connecting the USB port

In order to remotely control the device via this port, connect the device with a PC using the included USB cable and switch the device on.

2.3.10.1 Driver installation (Windows)

On the initial connection with a PC the operating system will identify the device as new hardware and will try to install a driver. The required driver is for a Communications Device Class (CDC) device and is usually integrated in current operating systems such as Windows 7 or 10. But it is strongly recommended to use the included driver installer (USB stick) to gain maximum compatibility of the device to our softwares.

2.3.10.2 Driver installation (Linux, MacOS)

We can’t provide drivers or installation instructions for these operating systems. Whether a suitable driver is available is best found out by searching the Internet.

2.3.10.3 Alternative drivers

In case the CDC driver described above are not available on your system, or for some reason do not function correctly, commercial suppliers can help. Search the Internet for suppliers using the keywords “cdc driver windows“ or “cdc driver linux“ or “cdc driver macos“.

2.3.11 Initial commission

For the rst start-up after purchasing and installing the device, the following procedures have to be executed:

• Conrm that the connection cables to be used are of a satisfactory cross section

• Check that the default settings for set values, safety and monitoring functions and communication are suitable

for your application and change them where necessary, as described in the manual

• In case of remote control via PC, read the additional documentation for interfaces and software

• In case of remote control via the analog interface, read the section in this manual concerning analog interfaces

and, where needed, other appropriate documentation especially concerning the use of such interfaces

2.3.12 Initial network setup

The device is delivered with default network parameters (see „3.4.3.6. Menu “Communication”“). The Ethernet/ LAN port is immediately ready for use after the initial commission.

For wiring, i.e. the hardware connection to a network, contact and ask your IT manager or any similar responsible person. Network cable of common type (CAT5 or better) can be used.

In order to set up the network parameter to your needs, you have two options: the setup menu or the device’s website. For the conguration in the setup menu please refer to „3.4.3.6. Menu “Communication”“.

For the conguration via the device’s website, you need the device to be connected to a network or directly to a PC which can access the default IP 192.168.0.2.

► How to do the network setup on the device website

1. In case the device display is in any kind of menu, lave menu to main display.

2. Open the device website in a browser by entering the default IP (http://192.168.0.2) or the default host name

(http://Client, only possible if there is a running DNS in the network) into the URL box.

3. After the website has been completely loaded, check the status eld item “Access” to show the status “free”.

In case it shows di󰀨erent, the device is either already in remote control (rem) or blocked from remote control (local). If it shows “local”, rst remove the block. Refer to section „3.5.2. Control locations“ to do that.

4. If it says “rem” in the “Access” item, skip to step 5. Else enter command syst:lock on (attention! space

before on) into the SCPI command box and send with return key. Check if item “Access” in status eld changes to “rem-eth” (means: remote Ethernet).

5. Switch to page CONFIGURATION (upper left corner) and set up the network parameters as well as the port

here resp. activate DHCP and submit the change with SUBMIT button.

6. Wait a few seconds before testing the new IP.

2.3.13 Commission after a rmware update or a long period of non-use

In case of a rmware update, return of the equipment following repair or a location or conguration change, similar measures should be taken to those of initial start up. Refer to „2.3.11. Initial commission“.

Only after successful checking of the device as listed may it be operated as usual.

3. Operation and application

3.1 Important notes

3.1.1 Personal safety

• In order to guarantee safety when using the device, it is essential that only persons operate

the device who are fully acquainted and trained in the required safety measures to be taken

when working with dangerous electrical voltages

• For models which can generate a voltage which is dangerous by contact, or is connected to such, the included DC terminal cover, or an equivalent, must always be used

• Whenever the load and DC output are being re-congured, the device should be disconnected from the mains, not only the DC output switched o󰀨!

3.1.2 General

• Unloaded operation isn’t considered as a normal operation mode and can thus lead to false measurements, for example when calibrating the device

• The optimal working point of the device is between 50% and 100% voltage and current

• It’s recommended to not run the device below 10% voltage and current, in order to make sure

technical specications like ripple and transient times are met

PS 9000 3U Series

3.2 Operating modes

A power supply is internally controlled by di󰀨erent control or regulation circuits, which shall bring voltage, current and power to the adjusted values and hold them constant, if possible. These circuits follow typical laws of control systems engineering, resulting in di󰀨erent operating modes. Every operating mode has its own characteristics which is explained below in short form.

3.2.1 Voltage regulation / Constant voltage

Voltage regulation is also called constant voltage operation (CV). The DC output voltage of a power supply is held constant on the adjusted value, unless the output current or the

output power according to P = U will automatically change to constant current or constant power operation, whatever occurs rst. Then the output voltage can’t be held constant anymore and will sink to a value resulting from Ohm’s law.

While the DC output is switched on and constant voltage mode is active, then the condition “CV mode active” will be indicated on the display by the abbreviation CV and this message will be passed as a signal to the analog interface, as well stored as status which can be read via digital interface.

3.2.1.1 Transient time after load step

For constant voltage mode (CV), the technical date “Transient time after load step” (see 1.8.3 resp. 1.8.4) denes a time that is required by the internal voltage regulator of the device to settle the output voltage after a load step. Negative load steps, i.e. high load to lower load, will cause the output voltage to overshoot for a short time until compensated by the voltage regulator. The same occurs with a positive load step, i.e. low load to high load. There the output collapses for a moment. The amplitude of the overshoot resp. collapse depends on the device model, the currently adjusted output voltage and the capacity on the DC output and can thus not be stated with a specic value.

Depictions:

Example for a negative load step: the DC output will rise above the adjusted value for a short time. t = transient time to settle the output voltage.

PS 9000 3U Series

3.2.2 Current regulation / constant current / current limiting

Current regulation is also known as current limitation or constant current mode (CC). The DC output current is held constant by the power supply as soon as the output current owing to the load

reaches the adjusted current set value. The actual current results from the output voltage and the load’s true resistance. As long as the output current is lower than the adjusted current set value, the device will be either in constant voltage or constant power mode. If, however, the power consumption reaches the adjusted power set

value, the device will automatically switch to power limitation and set the output current according to I

UIN , even if the current set value is higher. While the DC output is switched on and constant current mode is active, then the condition “CC mode active” will be

indicated on the display by the abbreviation CC, as well stored as status which can also be read via digital interface.

3.2.3 Power regulation / constant power / power limiting

Power regulation, also known as power limiting or constant power (CP), keeps the DC output power of a power supply constant if the current owing to the load

in relation to the actual output voltage and the resistance of the load reaches the

adjusted power set value according to P = U * I resp. P = U² / R. The power limiting then regulates the output current according to I = sqr(P / R), where R is the load’s resistance.

Power limiting operates according to the auto-range principle such that at lower

output voltages higher current ows and vice versa, all to maintain constant power

within the range PN (see diagram to the right)

Constant power operation primarily impacts the output current. This means, the adjusted maximum output current can’t be achieved if the maximum power value limits the output current according to I = P / U. The adjustable set value of current, as indicated in the display, is always only an upper limit.

While the DC output is switched on and constant power mode is active, then the condition “CP mode active” will be shown on the display by the abbreviation CP, as well stored as status which can also be read via digital interface.

3.3 Alarm conditions

This section only gives an overview about device alarms. What to do in case your device indicates an alarm condition is described in section „3.6. Alarms and monitoring“.

As a basic principle, all alarm conditions are signalled optically (Text + message in the display), acoustically (if activated) and as a readable status via the digital interface. With any alarm occurring, the DC output of the device is switched o󰀨. In addition, the alarms OT and OVP are reported as signals on the analog interface.

3.3.1 Power Fail

Power Fail (PF) indicates an alarm condition which may have various causes:

• AC input voltage too low (mains undervoltage, mains failure)

• Defect in the input circuit (PFC)

Switching o the device by the mains switch can’t be distinguished from a mains blackout and thus the device will signalise a PF alarm every time the device is switched o. This can be

ignored. The same signal causes the microcontroller to internally save the set values and the DC output condition.

3.3.2 Overtemperature

An overtemperature alarm (OT) can occur if an excess temperature inside the device causes to switch o󰀨 the DC output. This alarm condition is shown as the message “Alarm: OT” in the display. In addition, the condition will be passed as a signal to the analog interface, as well as alarm status and counter which both can be read via digital interface. After cooling down, the device can automatically switch the power stage back on, depending on the setting of parameter “DC output after OT alarm”. See section 3.4.3.1.

3.3.3 Overvoltage

An overvoltage alarm (OVP) will switch o󰀨 the DC output and can occur if:

• the power supply itself, as a voltage source, generates an output voltage higher than set for the overvoltage alarm

limit (OVP, 0...110% U

) or the connected load somehow returns voltage higher than set for the overvoltage

Nom

alarm limit

• the OV threshold has been adjusted too close above the output voltage. If the device is in CC mode and if it then experiences a negative load step, it will make the voltage rise quickly, resulting in an voltage overshoot for a short moment which can already trigger the OVP

This function serves to warn the user of the power supply acoustically or optically that the device probably has generated an excessive voltage which could damage the connected load application.

The device isn’t tted with protection from external overvoltage.

3.3.4 Overcurrent

An overcurrent alarm (OCP) will switch o󰀨 the DC output and can occur if:

• The output current in the DC output reaches the adjusted OCP limit.

This function serves to protect the connected load application so that this isn’t overloaded and possibly damaged due to an excessive current.

3.3.5 Overpower

An overpower alarm (OPP) will switch o󰀨 the DC output and can occur if:

• the product of the output voltage and output current in the DC output reaches the adjusted OPP limit.

This function serves to protect the connected load application so that this isn’t overloaded and possibly damaged due to an excessive power consumption.

3.4 Manual operation

3.4.1 Switching the device on

The device should, as far as possible, always be switched on using the rotary switch on the front of the device. Alternatively this can take place using an external cutout (contactor, circuit breaker) of suitable current capacity.

After switching on, the display will show the manufacturers logo for a few seconds, plus some information like

device model, rmware version(s), serial number and item number and will then be ready for use. In setup (see

section „3.4.3. Conguration in the setup menu“) in the second level menu “General settings” is an option “Output after power ON” in which the user can determine the condition of the DC output after power-up. Factory setting

here is “OFF”, meaning that the DC output on power-up is always switched o󰀨. Selection “Restore” means that the last condition of the DC output will be restored, either on or o󰀨. All set values are always saved and restored.

For the time of the start phase the analog interface can signal undened statuses on the output pins such as OT or OVP. Those signals must be ignored until the device has nished booting

and is ready to work.

3.4.2 Switching the device o󰀨

On switch-o󰀨 the last output condition and the most recent set values are saved. Furthermore, a PF alarm (power failure) will be reported, but can be ignored.

The DC output is immediately switched o󰀨 and after a short while fans will shut down and after another few seconds the device will be completely powered o󰀨.

3.4.3 Conguration in the setup menu

The setup menu serves to congure all operating parameters which are not constantly required. It can be entered by pushing , but only while the DC output is switched o󰀨. See gures below.

If the DC output is switched on the settings menu will not be shown, but the quick menu and some status information.

Menu navigation is done with the pushbuttons , and . Parameters (values, settings) are set using the rotary knobs.

The assignments of the rotary knobs, if multiple values can be set in a particular menu, is always the same: parameters on the left-hand side -> left-hand knob, parameters on the right-hand side -> right-hand knob



Some setting parameters are self-explanatory, others are not. The latter will be explained on the pages following.

Analog interface Rem-SB Determines with “Normal” (default), that the function and levels of input Rem-SB

are as described in „3.5.4.4. Analog interface specication“. With selection “invert-

ed”, the described function is logically inverted. Also see example a) in „3.5.4.7. Application examples“.

Analog interface pin 6 Pin 6 of the analog interface (see section 3.5.4.4) is by default assigned to only signal

the device alarms OT and PF. This parameter allows to also enable signaling only one of both (3 possible combinations):

OT = Enable/disable signaling of alarm OT on pin 6 PF = Enable/disable signaling of alarm PF on pin 6

Analog interface pin 14 Pin 14 of the analog interface (see section 3.5.4.4) is by default assigned to only

signal the device alarm OVP. This parameter allows to also enable signaling further device alarms (7 possible combinations):

OVP = Enable/disable signaling of alarm OVP on pin 14 OCP = Enable/disable signaling of alarm OCP on pin 14 OPP = Enable/disable signaling of alarm OPP on pin 14

Analog interface pin 15 Pin 15 of the analog interface (see section 3.5.4.4) is by default assigned to only

signal the regulation mode CV. This parameter allows to enable signaling a di󰀨erent device status (2 options):

Regulation mode = Enable/disable signaling of CV reg mode on pin 15 DC status = Enable/disable signaling of DC output status on pin 15

Analog Rem-SB action Since Firmware 2.03, the input REM-SB of the analog interface can be used to

control the DC output of the device even without remote control via analog interface being activated. This setting determines the type of action:

• DC OFF = Toggling the pin only switches the DC output o󰀨

• DC ON/OFF = If the DC output has been switched on before, toggling the pin

can switch the output o󰀨 and on again

DC output after power ON Determines the condition of the DC output after power-up.

• OFF = DC output is always o󰀨 after switching on the device.

• Restore = DC output condition will be restored to the condition prior to switch o󰀨.

DC output after PF alarm Determines how the DC output shall react after a power fail (PF) alarm has

occurred:

• OFF = DC output will be switched o󰀨 and remain until user action

• AUTO = DC output will switch on again after the PF alarm cause is gone and if

it was switched on before the alarm occurred

DC output after remote Determines the condition of the DC output after leaving remote control either man-

ually or by command.

• OFF = DC output will be always o󰀨 when switching from remote to manual

• AUTO = DC output will keep the last condition

3.4.4 Adjustment limits

By default, all set values (U, I, P) are freely adjustable from 0 to 102% of rated value. This may be obstructive in some applications, especially for protection of applications against overcurrent. Therefore upper and lower limits for current and voltage can be set which limit the range of the adjustable set values.

For power only an upper value limit can be set. These limits apply to every kind setting a value. That also includes remote control via analog or digital interface.

In remote control, the global range of 0...102% (digital) resp. 0...5 V / 0...10 V remains, only narrowed by the limits dened here.

An example: you would dene the limits for a model with 80 V, 170 A and 5 kW as depicted in the screen above, with U-min = 10 V and U-max = 75 V. In analog remote control, the active control voltage range for mode 0...10 Vresults as 1.25 V...9.375 V. As soon as the device is switched to analog remote control, it would put out minimum 10V, even there is nothing connected to voltage control input VSEL.

Beyond those limits, values given by digital commands are not accepted and will return an error (when using SCPI). Values given from analog control voltages are ignored (clipping).

► How to congure the adjustment limits

1. Switch o󰀨 the DC output and push button to call the setup menu.

2. Push button to call sub menu “Settings”. In the sub menu navigate to “Limit Settings” and push

again.

3. In the screen you can now adjust the settings I-min, I-max, U-min, U-max and P-max with the rotary knobs.

Switching between values is done with the arrow buttons .

4. Accept the settings with or discard them with .

The adjustment limits are coupled to the set values. It means, that the upper limit (-max) may not be set lower than the corresponding set value. Example: If you wish to set the limit for the

current set value I-max to 120 A while the currently adjusted current set value is 150 A, then the set value rst would have to be reduced to 120 A or less.

The same applies vice versa when adjusting I-min.

3.4.5 Manual adjustment of set values

The set values for voltage, current and power are the fundamental operating possibilities of a power supply and hence the two rotary knobs on the front of the device are usually assigned two of the three values in manual operation. Default assignment is voltage and current.

The set values can only be adjusted with the rotary knobs.

Entering a value changes it at any time, no matter if the output is switched on or o.

When adjusting the set values, upper or lower limits may come into eect. See section „3.4.4.

Adjustment limits“. Once a limit is reached, the display will show a note like “Limit: U-max” etc. or “[i]” for 1.5 seconds.

► How to adjust values U, I or P with the rotary knobs

1. First check whether the value to be changed is assigned to one of the rotary knobs. The assignment can be

changed by switching the assignment of the right-hand rotary knob with the arrow buttons.

2. With mode UI selected and as long as the main display is active, turn the left-hand knob to adjust output

voltage and the right-hand knob to adjust the output current. In mode UP, turn the right-hand knob to adjust

the output power. The arrow buttons can be used to toggle between adjustment of current and power set value.

3. Any set values can be adjusted with the adjustment limits. For switching the digit to adjust, push the rotary

knob that you are currently using to adjust the value. Every push moves the cursor under the digit in clockwise order:

3.4.6 Switching the main screen view

The main screen, also called status page, with its set values, actual values and device status can be switched from the standard view mode with three values to a simpler mode which only shows two physical values.

The advantage of the alternative view mode is that both actual values are displayed with bigger numbers, so they read be read from a larger distance. Refer to „3.4.3.7. Menu “HMI Setup”“ to see where to switch the view mode in the MENU. Comparison:

Layout 1 (standard) Layout 2 (alternative)

Di󰀨erences of layout 2:

3.4.7 The quick menu

The quick menu o󰀨ers access to some feature which are also accessible from the regular menu, but here they can be used while the DC output is switched on.

The quick menu is shown when pressing the button and looks like this:

Navigation in the menu is also done with arrow buttons / and .

For example, in this menu it’s possible to preset the output values and to submit with button which allows for set value steps which would not be possible when rotating a knob. Furthermore, the HMI lock can be activated here in a shorter way.

3.4.8 Switching the DC output on or o󰀨

The DC output of the device can be manually or remotely switched on and o󰀨. This can be restricted in manual operation by the control panel being locked.

Switching the DC output on during manual operation or digital remote control can be disabled by pin REM-SB of the built-in analog interface. For more information refer to 3.4.3.1 and example a) in 3.5.4.7.

► How to manually switch the DC output on or o󰀨

1. As long as the control panel (HMI) isn’t fully locked press the button ON/OFF. Otherwise you are asked to

disable the HMI lock rst.

2. This button toggles between on and o󰀨, as long as a change isn’t restricted by an alarm or the device is

locked in “remote”. The current condition is displayed with the green LED in button .

► How to remotely switch the DC output on or o󰀨 via the analog interface

1. See section “„3.4.3. Conguration in the setup menu“.

► How to remotely switch the DC output on or o󰀨 via the digital interface

1. See the external documentation “Programming Guide ModBus & SCPI” if you are using custom software,

or refer to the external documentation of LabView VIs or other software provided by the manufacturer.

3.5 Remote control

3.5.1 General

Remote control is principally possible via any of the built-in interface ports USB, Ethernet/LAN, analog or optional GPIB. Important here is that only the analog or any digital interface can be in control. It means that if, for example, an attempt were to be made to switch to remote control via the digital interface whilst analog remote control is active (pin REMOTE = LOW) the device would report an error at the digital interface. In the opposite direction a switch-over via pin REMOTE would be ignored. In both cases, however, status monitoring and reading of values are always possible.

3.5.2 Control locations

Control locations are those locations from where the device can be controlled. Essentially there are two: at the device (manual operation) and outside (remote control). The following locations are dened:

Displayed location Description

- If neither of the other locations is displayed then manual control is active and access from

the analog or digital interfaces is allowed. This location isn’t explicitly displayed

Remote Remote control via any interface is active Local Remote control is locked, only manual operation is allowed.

Remote control may be allowed or inhibited using the setting “Allow remote control” (see „3.4.3.1. Menu “General Settings”“). In inhibited condition the status “Local” will be displayed in the status area (lower half, middle) of the

display. Activating the inhibit can be useful if the device is remotely controlled by software or some electronic device, but it is required to make adjustments at the device or deal with emergency, which would not be possible remotely.

Activating condition “Local” causes the following:

• If remote control via the digital interface is active (“Remote”), then remote control is immediately terminated and must be reactivated at the PC once “Local” is no longer active

• If remote control is via the analog interface is active (“Remote”), then remote operation is only interrupted until remote control is allowed again, because pin REMOTE continues to signal “remote control = on”. Exception: if the level of pin REMOTE is changed to HIGH during the “Local” phase

3.5.3 Remote control via a digital interface

3.5.3.1 Selecting an interface

The device only supports the built-in digital interfaces USB and Ethernet (standard models) resp. GPIB (optional). For USB, a standard USB cable is included in the delivery, as well as a driver for Windows on the USB stick. The

USB interface requires no setup. The Ethernet interface typically requires network setup (manual or DHCP), but can also be used with its default

parameters right from the start. The GPIB interface requires you to select a unique address in case it is connected to other GPIB bus members.

3.5.3.2 General

For the network port installation refer to „1.9.8. Ethernet port“.

The digital interface require little or no setup for operation and can be directly used with their default conguration. All specic settings will be permanently stored, but could also be reset to defaults with the setup menu item “Reset Device”.

Via the digital interface primarily the set values (voltage, current, power) and device conditions can be set and monitored. Furthermore, various other functions are supported as described in separate programming documentation.

Changing to remote control will retain the last set values for the device until these are changed. Thus a simple voltage control by setting a target value is possible without changing any other values.

3.5.3.3 Programming

Programming details for the interfaces, the communication protocols etc. are to be found in the documentation “Programming Guide ModBus & SCPI“ which is supplied on the included USB stick or which is available as download from the manufacturer’s website.

3.5.4 Remote control via the analog interface (AI)

3.5.4.1 General

The built-in, galvanically isolated, 15-pole analog interface (short: AI) is on the rear side of the device o󰀨ers the following possibilities:

• Remote control of current, voltage and power

• Remote status monitoring (CV, DC output)

• Remote alarm monitoring (OT, OVP, PF, OCP, OPP)

• Remote monitoring of actual values

• Remote on/o󰀨 switching of the DC output

Setting the three set values via the analog interface always takes place concurrently. It means, that for example the voltage can’t be given via the AI and current and power set by the rotary knobs, or vice versa.

The OVP set value and other supervision (events) and alarm thresholds can’t be set via the AI and therefore must be adapted to the given situation before the AI is put in operation. Analog set values can be fed in by an external voltage or generated by the reference voltage on pin 3. As soon as remote control via the analog interface is activated, the values displayed will be those provided by the interface.

The AI can be operated in the common voltage ranges 0...5 V and 0...10 V in each case 0...100% of the nominal value. The selection of the voltage range can be done in the device setup. See section „3.4.3. Conguration in the setup menu“ for details.

The reference voltage sent out from Pin 3 (VREF) will be adapted accordingly and is then: 0-5 V: Reference voltage = 5 V, 0...5 V set values (VSEL, CSEL, PSEL) correspond to 0...100% nominal values,

0...100% actual values correspond to 0...5 V at the actual value outputs (CMON, VMON).

0-10 V: Reference voltage = 10 V, 0...10 V set values (VSEL, CSEL, PSEL) correspond to 0...100% nominal values,

0...100% actual values correspond to 0...10 V at the actual value outputs (CMON, VMON).

Input of excess set values (e.g. >5 V in selected 5 V range or >10 V in the 10 V range) are clipped by setting the set value at 100%.

Before you begin, please read these important notes about the use of the interface:

After powering the device and during the start phase the AI signals undened statuses on the output pins such as ALARMS1. Those must be ignored until is ready to work.

• Analog remote control of the device must be activated by switching pin REMOTE (5) rst

• Before the hardware is connected that will control the analog interface, it shall be checked that it can’t provide

voltage to the pins higher than specied

• Set value input, such as VSEL, CSEL and PSEL, must not be left unconnected (i.e. oating)

• It is always required to provide all three set values at once. In case any of the set values isn’t used for adjustment,

it can be tied to a dened level or connected to pin VREF (solder bridge or di󰀨erent), so it gives 100%

3.5.4.2 Resolution and sample rate

The analog interface is internally sampled and processed by a digital microcontroller. This causes a limited resolution of analog steps. The resolution is the same for set values (VSEL etc.) and actual values (VMON/CMON) and is 26214. Due to tolerances, the truly achievable resolution can be slightly lower.

There is furthermore a max. sample rate of 500 Hz. It means, the device can acquire analog set values and states on digital pins 500 times per second.

3.5.4.3 Acknowledging device alarms

In case of a device alarm occurring during remote control via analog interface, the DC output will be switched o󰀨 the same way as in manual control. The device would indicate an alarm (see 3.6.2) in the front display and, if activated, acoustically and also signal most of them on the analog interface. Which alarms actually are signaled can be set up in the device conguration menu (see „3.4.3.1. Menu “General Settings”“).

Some device alarms (OVP, OCP and OPP) have to be acknowledged. Also see „3.6.2. Device alarm handling“. Acknowledgment is done with pin REM-SB switching the DC output o󰀨 and on again, means a HIGH-LOW-HIGH edge (min. 50ms for LOW), when using the default level setting for this pin.

sinking current.

3.5.4.7 Application examples

a) Switching o󰀨 the DC output via the pin REM-SB

A digital output, e.g. from a PLC, may be unable to cleanly pull down the pin as it may not be of low enough resistance. Check the specication of the controlling

application. Also see pin diagrams above.

In remote control, pin REM-SB is used to switch the DC output of the device on and o󰀨. This function is also available without remote control being active and can on one hand block the DC output from being switched on in manual or digital remote control and on the other hand the pin can switch the DC output on or o󰀨, but not standalone. See below at “Remote control has not been activated”.

It is recommended that a low resistance contact such as a switch, relay or transistor is used to switch

the pin to ground (DGND). Following situations can occur:

• Remote control has been activated

During remote control via analog interface, only pin REM-SB determines the states of the DC output, according to the levels denitions in 3.5.4.4. The logical function and the default levels can be inverted by a parameter in the setup menu of the device. See 3.4.3.1.

If the pin is unconnected or the connected contact is open, the pin will be HIGH. With parameter

“Analog interface REM-SB” being set to “Normal”, it requests “DC output on”. So when activating

remote control, the DC output will instantly switch on.

b) Remote control of current and power

Requires remote control to be activated (Pin REMOTE = LOW) The set values PSEL CSEL are generated from, for example, the

reference voltage VREF using potentiometers for each. Hence the

power supply can selectively work in current limiting or power limit-

ing mode. According to the specication of max. 5 mA for the VREF output, potentiometers of at least 10 kΩ must be used.

The voltage set value VSEL is permanently assigned to VREF and will thus be permanently 100%.

If the control voltage is fed in from an external source it is necessary to consider the input voltage ranges for set values (0...5 V oder 0...10 V).

Use of the input voltage range 0...5 V for 0...100% set value halves the eective resolution.

c) Reading actual values

Via the AI the output values for current and voltage can be monitored. These can be read using a standard multimeter or similar.

3.6 Alarms and monitoring

3.6.1 Denition of terms

Device alarms (see „3.3. Alarm conditions“) are dened as conditions like overvoltage or overtemperature, signalled in any form to the user of the device in order to take notice.

Those alarms are always indicated in the front display as readable abbreviated text, as well as status readable via digital interface when controlling or just monitoring remotely and, if activated, emitted as audible signal (buzzer). Furthermore, the most important alarms are also signalled by output pins on the analog interface.

There is furthermore an alarm history available in the sub menu “Overview”. It counts alarms that occurred since the last time the unit was switched on, for statistics and later check.

3.6.2 Device alarm handling

A device alarm incident will usually lead to DC output switch-o󰀨. Some alarms must be acknowledged (see below), which can only happen if the cause of the alarm isn’t persistent anymore. Other alarms acknowledge themselves if the cause has vanished, like the OT and the PF alarm.

► How to acknowledge an alarm in the display (during manual control)

1. Push button once.

► How to acknowledge an alarm on the analog interface (during analog remote control)

1. Switch o󰀨 the DC output by pulling pin REM-SB to the level that corresponds to “DC output o󰀨” switch it on

again. See section „3.5.4.7. Application examples“ for levels and logic.

► How to acknowledge an alarm in the alarm bu󰀨er/status (during manual control)

1. Read the error bu󰀨er (SCPI protocol) or send a specic command to acknowledge, i.e. reset alarms (Mod-

Bus RTU).

Some device alarms are congurable by adjusting a threshold:

3.7 Control panel (HMI) lock

In order to avoid the accidental alteration of a value during manual operation the rotary knobs or the key strip of the control panel (HMI) can be locked so that no alteration will be accepted without prior unlocking. For additional safety, the panel lock can be secured by a PIN in order to only allow access from authorised personnel.

► How to lock the HMI

1. Switch o󰀨 the DC output and push button to call the setup menu.

2. In the menu navigate to “HMI Setup” and push . Then in the sub menu navigate to “HMI Lock” and

3.8 Loading and saving a user prole

The menu “Proles” serves to select between a default prole and up to 5 user proles. A prole is a collection of all settings and set values. Upon delivery, or after a reset, all 6 proles have the same settings and all set values are 0. If the user changes settings or sets target values then these create a work prole which can be saved to one of the 5 user proles. These proles or the default one can then be switched. The default prole is read-only.

The purpose of a prole is to load a set of set values, settings limits and monitoring thresholds quickly without having to readjust these. As all HMI settings are saved in the prole, including language, a prole change can also be accompanied by a change in HMI language.

On calling up the menu page and selecting a prole the most important settings can be seen, but not changed.

3.9 Other applications

3.9.1 Parallel operation in Share bus mode

Multiple devices of same kind and model can be connected in parallel in order to create a system with higher total current and hence higher power. To achieve that, the units have to be connected on their DC outputs and their Share Bus. The Share Bus will balance the units in their internal voltage regulation and thus current regulation, which will result in a balanced load distribution. It means that the Share bus is only e󰀨ective in constant voltage operation.

In the parallel operation, a specic unit, a “Share Bus master”, has to be picked as leading unit which drives the “Share Bus slaves”. The master unit will remain fully controllable, also via analog or digital interface. The slaves, however, are restricted regarding set value adjustment. Their set values are just limits for the units while it is controlled via the Share Bus. A slave unit still can be controlled remotely, but not regarding output voltage. All slaves can be monitored (actual values,status), no matter via analog or digital interface.

The Share Bus only control the process variable U (voltage). It means, the DC outputs of slave units have to be switched on or o either manually or remotely, which is very easy in analog remote control, because the related pins REM-SB could simply be connected in parallel, too. Furthermore, the Share Bus makes the set values of current and power ineective on the slave

units, so it is recommended to carefully set the protection thresholds OCP and OPP.

3.9.1.1 Wiring the DC outputs

The DC output of every unit in the parallel operation is simply connected to the next unit using cables with cross section according to the maximum current and with short as possible length.

3.9.1.2 Wiring the Share bus

The Share bus is wired from unit to unit with an ideally twisted pair of cables with non-critical cross section. We recommend to use 0.5 mm² to 1.0 mm².

The Share bus is poled. Take care for correct polarity of the wiring!

A max. of 16 units can be connected via Share bus.

3.9.1.3 Conguring units for Share Bus operation

For correct Share Bus operation in parallel connection, the formerly picked master unit has to be configured as “Share Bus master”. By default, these power supplies are set as “Share Bus slaves”, so that this configuration step isn’t necessary for all slave units.

Only one unit in the Share Bus connection must be congured as Share Bus master, else the Share Bus won’t work.

► How to configure a device as Share Bus master

1. Switch o󰀨 the DC output and push button to call the setup menu. Push again to enter sub

menu “Settings”.

2. In the sub menu navigate to “General Settings” and push once again.

3. Use arrow button to navigate to item “Share Bus mode” on the 2nd page and switch to setting “Mas-

ter” by using the right-hand rotary knob.

4. Accept the settings with or discard them with .

3.9.1.4 Operating the Share Bus system

After successful conguration and initialisation of the master and slave units, it is recommended to check all set values and protection settings of all slaves and possibly adjust to identical values.

The slaves can be controlled manually as usual or remotely via the analog or via digital interfaces, but they don’t react to voltage set values changes the same way as the master. They can, if needed, be monitored by reading actual values and status.

The master unit isn’t restricted and can be used like a stand-alone unit.

3.9.1.5 Alarms and other problem situations

Parallel operation, due to the connection of multiple units and their interaction, can cause additional problem situations which do not occur when operating individual units. For such occurrences the following regulations have been dened:

• If one or more slave units are switched o󰀨 on the AC side (power switch, supply undervoltage) and come back later, they’re automatically included again in the system. The remaining units will continue to work without interruption, but the entire system will provide less power

• If the DC output of the master unit is switched o󰀨 due to a defect or overheating, then the total parallel system

can provide no output power

• If accidentally multiple or no units are dened as master the Share Bus parallel system can’t be initialised

In situations where one or multiple units generate a device alarm like OV, PF or OT following applies:

• Any alarm of a slave is indicated on the slave’s display only

3.9.2 Series connection

Series connection of two or multiple devices is basically possible. But for reasons of safety and isolation, some restrictions apply:

• Both, negative (DC-) and positive (DC+) output poles, are connected to PE via type X capacitors

• None DC minus pole of any unit in the series connection must have a potential against ground

(PE) higher than specied in the technical data! The maximum allowed potential shift varies from model to model and is di󰀨erent for DC plus and DC minus

• The Share Bus must not be wired and used!

• Remote sensing must not be used!

• Series connection is only allowed with devices of the same kind and model, i.e. power supply with

power supply, like for example PS/PSI 9080-170 3U with PSI 9080-170 3U or PS 9080-170 3U

Series connection in Master-Slave mode isn’t supported. It means, all units have to controlled separately regarding set values and DC output status, whether it is manual control or remote control (digital or analog). Due to the max. allowed potential shift on the DC output certain models are not allowed for series connection at all.

Analog interfaces on the units in serial connection can be connected in parallel, because they are galvanically isolated. It is also allowed to ground the GND pins of the analog interfaces connected in parallel, which may happen automatically, when connecting them to a controlling device such as a PC, where grounds are directly tied to PE.

In digital remote control, an almost synchronous control can be achieved by using any available Ethernet interface module and sending message as broadcast, so they address multiple units at once.

3.9.3 Operation as battery charger

A power supply can be used as a battery charger, but with some restrictions, because it misses a battery supervision and a physical separation from the load in form of a relay or contactor, which is featured with some real

battery chargers as a protection. Following has to be considered:

• No false polarity protection inside! Connecting a battery with false polarity will damage the power supply severely, even if it isn’t powered.

• Models from 200 V rating feature an internal discharge circuit for faster down-ramping of the output voltage after switching the output o󰀨. This small load can discharge the battery more or less slowly while the DC output is switched on and the power supply’s output voltage is set to be lower than the battery voltage. This would, however, not occur when the power supply isn’t powered at all. It is thus recommended to leave the DC output switched o󰀨 as long as the battery isn’t supposed to be charged.

3.9.4 Two quadrants operation (2QO)

3.9.4.1 Introduction

This way of operating refers to the use of a source, in this case a power supply

of series PS 9000 3U (only from revision 2, see type label), and a sink, in this case a series ELR 9000 or series EL 9000 B electronic load. The source and the sink function alternatingly in order to test a device, such as a battery, by deliberately charging and discharging it as part of a functional or nal test.

The user can decide whether the system is operated manually or the power

supply only as the dominant unit or both devices should be controlled by PC. We recommend to focus on the power supply, which is intended to control the load via the Share Bus connection. The two quadrants operation is only suitable for constant voltage operation (CV).

3.9.4.2 Connecting devices to a 2QO

There are a number of possibilities to connect source(s) and sink(s) to make a 2QO:

U-

E-LOAD PSU

Share-Bus

E.U.T

I+

A combination of source and sink can only map the quadrants I + II. This means that only positive voltages are possible. The positive current is generated by the source or application and the negative current ows into the load..

The maximum approved limits for the application should be set in the power supply. This can be done via the interface. The electronic load should preferably be in operating mode CV. The load will then, using the Share Bus, control the output voltage of the power supply.

Typical applications:

• Fuel cells

• Capacitor tests

• Motor driven applications

• Electronic tests where a high dynamic discharge is required.

Conguration A:

1 e-load and 1 power supply, plus 1 test object (E.U.T). This is he most common conguration for 2QO. The nominal

values for U,I and P of the two devices should match, such as ELR 9080-170 and PS 9080-170 3U. The system is controlled by the power supply, which has to be set to “Master” in the setup menu (parameter “Share Bus mode”).

Conguration B:

For adapting the total power of the power supply device to the

possibly higher input power of the load, the power supplies are connected via Master-Slave and the load’s current is shared across the power supplies when wiring the Share bus to gain a balanced load distribution. The system is controlled by one of the power supplies, which has to be set to “Master” in the setup menu (parameter “Share Bus mode”).

3.9.4.3 Settings on the devices

The master-slave settings in the MENU of the load device(s) also a󰀨ect the Share bus. For correct 2QO operation, all involved load units must be slaves on the Share bus. This is achieved by setting the master-slave mode to OFF or SLAVE, depending on if there is digital master-slave in use or not. For the one load that is master (setting: MASTER) in the master-slave system the additional parameter “PSI/ELR system” resp. “PSI/EL system” has to be activated.

On any of the power supplies, you need set parameter “Share bus mode” to MASTER. Also see 3.4.3.1. For safety of the connected E.U.T / D.U.T and to prevent damage, we recommend to adjust supervision thresholds

like OVP, OCP or OPP on all units to the desired levels, which will then switch o󰀨 the DC output resp. the DC input in case of excess.

3.9.4.4 Restrictions

After all electronic loads have been connected to the Sharebus with one power supply as master, they can’t limit their input voltage anymore to what you adjust as “U set” on the device. The correct voltage level comes from the 2QO master unit (power supply) and has to be adjusted there.

If the applications requires to use the remote sensing feature in order to achieve a higher voltage accuracy on the E.U.T. only the master must be wired its Sense connector.

Using the Sense input must be considered with caution, because it could increase the tendency

of oscillation.

3.9.4.5 Application example

Charging and discharging a battery with 24 V / 400 Ah, using conguration A from above.

• Power supply PS 9080-170 3U with: I

• Electronic load ELR 9080-170 set to: I

plus probably UVD = 20 V with event type “Alarm” to stop discharging at a certain low voltage threshold

• Assumption: battery has a voltage of 26 V at test start

• DC input(s) and DC output(s) of all units switched o󰀨

= 40 A (charging current, 1/10 of capacity), P

Set

= max. discharging current of the battery (eg. 100 A), P

Set

= 5000 W

Set

= 3500 W,

Set

In this combination of devices it is recommended to always switch on the DC output of the

source rst and then the DC input of the sink.

1. Discharge of the battery to 24 V

Setup: Voltage on the power supply set to 24 V, DC output of power supply and DC input of load activated Reaction: the e-load will load the battery with a maximum current of 40 A in order to discharge it to 24 V. The power

supply delivers no current at this moment, because the battery voltage is still higher than what is adjusted on the power supply. The load will gradually reduce the input current in order to maintain the battery voltage at 24 V. Once the battery voltage has reached 24 V with a discharge current of approx. 0 A, the voltage will be maintained at this level by charging from the power supply.

The power supply determines the voltage setting of the load via the Share bus. In order to avoid deep discharge of the battery due to accidentally setting the voltage on the power to a very low

value, it is recommended to congure the undervoltage detection feature (UVD) of the load, so it will switch o the DC input when reaching the discharge voltage. The settings of the load, as given via the Share bus, can’t be read from the load’s display.

2. Charging the battery to 27 V

Setup: Voltage on the power supply set to 27 V Reaction: the power supply will charge the battery with a maximum current of 40 A, which will gradually reduce

with increasing voltage as a reaction to the changing internal resistance of the battery. The load absorbs no current at this charging phase, because it is controlled via the Share bus and set to a certain voltage, which is still higher than the actual battery voltage and the actual output voltage of the power supply. When reaching 27 V, the power supply will deliver only the current needed to maintain the battery voltage.

4. Service and maintenance

4.1 Maintenance / cleaning

The device needs no maintenance. Cleaning may be needed for the internal fans, the frequency of cleanse is depending on the ambient conditions. The fans serve to cool the components which are heated by the inherent power loss. Heavily dirt lled fans can lead to insu󰀩cient airow and therefore the DC output would switch o󰀨 too early due to overheating or possibly lead to defects.

Cleaning the internal fans can be performed with a vacuum cleaner or similar. For this the device needs to be opened.

4.2 Fault nding / diagnosis / repair

If the equipment suddenly performs in an unexpected way, which indicates a fault, or it has an obvious defect, this can’t and must not be repaired by the user. Contact the supplier in case of suspicion and elicit the steps to be taken.

It will then usually be necessary to return the device to the supplier (with or without guarantee). If a return for checking or repair is to be carried out, ensure that:

• the supplier has been contacted and it is claried how and where the equipment should be sent.

• the device is in fully assembled state and in suitable transport packaging, ideally the original packaging.

• a fault description in as much detail as possible is attached.

• if shipping destination is abroad, the necessary customs papers are attached.

4.2.1 Firmware updates

Firmware updates should only be installed when they can eliminate existing bugs in the rmware in the device or contain new features.

The rmware of the control panel (HMI), of the communication unit (KE) and the digital controller (DR), if necessary, is updated via the rear side USB port. For this the software EA Power Control is needed which is included with the device or available as download from our website together with the rmware update, or upon request.

However, be advised not to install updates promptly. Every update includes the risk of an inoperable device or system. We recommend to install updates only if...

• an imminent problem with your device can directly be solved, especially if we suggested to install an update

during a support case

• a new feature has been added which you denitely want to use. In this case, the full responsibility is transferred to you.

Following also applies in connection with rmware updates:

• Simple changes in rmwares can have crucial e󰀨ects on the application the devices are use in. We thus recommend to study the list of changes in the rmware history very thoroughly.

• Newly implemented features may require an updated documentation (user manual and/or programming guide, as well as LabView VIs), which is often delivered only later, sometimes signicantly later

PS 9000 3U Series

4.3 Calibration (readjustment)

4.3.1 Preface

The devices of series PS 9000 feature a function to re-adjust the most important DC output related values, which can help in case these values are out of tolerance. The procedure is limited to compensate small di󰀨erences of up to 1% or 2% of the ratings. There are several reasons which could make it necessary to readjust a unit: component aging, component deterioration, extreme ambient conditions, high frequent use.

In order to determine if a value is out of tolerance, the parameter must be veried rst with measurement tools of high accuracy and with at least half the error of the PS device. Only then a comparison between values displayed on the PS device and true DC output values is possible.

For example, if you want to verify and possibly readjust the output current of model PS 9080-510 3U which has 510 A maximum current, stated with a max. error of 0.2%, you can only do that by using a high current shunt with max. 0.1% error or less. Also, when measuring such high currents, it is recommended to keep the process short, in order to avoid the shunt heating up too much. It is furthermore recommended to use a shunt with at least 25% reserve.

When measuring the current with a shunt, the measurement error of the multimeter on the shunt adds to the error of the shunt and the sum of both must not exceed the max. error of the device under calibration.

4.3.2 Preparation

For a successful calibration and readjustment, a few tools and certain ambient conditions are required:

• A measurement device (multimeter) for voltage, with a max. error of half the PS’s voltage error. That measurement device can also be used to measure the shunt voltage when readjusting the current

• If the current is also going to be calibrated: a suitable DC current shunt, ideally specied for at least 1.25 times the max. output current of the PS and with a max. error that is half or less than the max. current error of the PS device

• Normal ambient temperature of approx. 20-25°C (68-77°F)

• An adjustable load, such as an electronic load, which is capable of consuming at least 102% of the max. voltage

and current of the PS device

Before you can start calibrating, a few measures have to be taken:

• Let the PS device warm up in connection with the voltage / current source

• In case the remote sensing input is going to be calibrated, prepare a cable for the remote sensing connector to

DC output, but leave it yet unconnected

• Abort any form of remote control, deactivate master-slave mode, set device to U/I mode

• Install the shunt between PS device and load and make sure the shunt is cooled somehow

• Connect external measurement device to the DC output or to the shunt, depending on whether the voltage is

going to be calibrated rst or the current

4.3.3 Calibration procedure

After the preparation, the device is ready to be calibrated. From now on, a certain sequence of parameter calibration is important. Generally, you don’t need to calibrate all three parameters, but it is recommended to do so.

Important:

• It is recommended to do the calibration of current before any voltage calibration

• When calibrating the voltage, the input “Sense” on the rear of the device must be disconnected

• During the calibration, the user is asked to enter measured values. If these value dier too much from the value measured by the device or wrong values are entered, the calibration fails and has to be repeated.

The calibration procedure, as explained below, is an example with model PS 9080-170 3U. Other models are treated the same way, with values according to the particular PS model and the required load.

4.3.3.1 Calibrating the set values

► How to calibrate the DC output voltage

1. Connect a multimeter to the DC output. Connect a load

and set it to approx. 5% of the nominal current of the power supply as load current, in this example ≈8 A.

2. In the display enter the setup menu with , then push

button . In the sub menu navigate to “Calibrate Device”. Push again.

3. In the next screen select “Voltage calibration” + , then “Calibrate output value” + 2x . The

power supply will switch the DC output on, set a certain output voltage and start to measure it (U-mon).

4. The next screen requests you to enter the measured output voltage from the multimeter at Measured

data=. Enter it using the right-hand rotary knob, just like would adjust a set value. Assure yourself the value

is correct and submit with .

5. Repeat point 4. for the next three steps (total of four steps).

► How to calibrate the DC output current

1. Set the load to >100% nominal current of the PS device, for the sample model with 170 A let’s say 173 A.

2. In the display enter the setup menu with , then push button . In the sub menu navigate to “Cal-

ibrate Device”. Push again.

3. In the next screen select “Current calibration” + , then “Calibrate output value” + 2x . The

device will switch on the DC output, set a certain current limit while loaded by the load or sink and start to

measure the output current (I-mon).

4. The next screen requests you to enter the output current Measured data= measured with the shunt. Enter

it using the right-hand rotary knob, just like would adjust a set value. Assure yourself the value is correct

and submit with .

5. Repeat point 4. for the next three steps (total of four steps).

4.3.3.2 Calibrating the remote sensing

In case you are generally using the remote sensing feature, no matter if in sink or source mode, it is recommended

to also calibrate it for best results. The procedure is identical to the calibration of voltage, except for it requires to have the sensing connector (Sense) on the rear to be plugged and connected with correct polarity to the DC output of the PS.

► How to calibrate the DC output voltage for remote sensing

1. Connect a load and set it to approx. 3% of the nominal current of the power supply as load current, in this

example ≈5 A. Connect the remote sensing input (Sense) to the load with correct polarity.

2. Connect an external multimeter to the DC terminal of the load.

3. In the display enter the setup menu with , then push button . In the sub menu navigate to “Cal-

ibrate Device”. Push again.

4. In the next screen select “Sense volt. calibration” + , then “Calibrate output value” + 2x .

5. The next screen requests you to enter the measured sensing voltage at Measured data=. Enter it using the

right-hand rotary knob, just like would adjust a set value. Assure yourself the value is correct and submit with .

6. Repeat point 5. for the next three steps (total of four steps).

4.3.3.3 Calibrating the actual values

Actual values of output voltage (with and without remote sensing) and output current are calibrated almost the same way as the set values, but here you don’t need to enter anything, just conrm the displayed values. Please proceed the above steps and instead of “Calibrate output value” select “Calibrate actual value” in the submenus. After the device shows measured values on display, wait at least 2s for measured value to settle and then simply

conrm with , until you are through all steps.

4.3.3.4 Save calibration data

After calibration you may furthermore enter the current date. To do so, navigate to menu item “Calibration date”

and enter the date in format YYYY / MM / DD and submit with .

Last but not least save the calibration data permanently conrming menu item “Save and exit” with .

Leaving the calibration selection menu without saving via “Save and exit” will discard calibration data and the procedure would have to be repeated!
