2. Adjust the Current encoder to set the current limit to approx. 10% of the unit rating.

3. Set Foldback to CC MODE.

4. Short the output terminals momentarily (approx. 0.5 sec.). Ensure that the output voltage falls
to zero, the Voltage display shows ”FOd ”, Current display shows ”FA I ” and the PROT red LED blinks.

5. Set Foldback to OFF. The output voltage remains zero.

6. Press OUTPUT button. Ensure that the output voltage returns to it’s last setting.

7. Turn the output off by pressing OUTPUT button. Ensure that the Voltage display shows ”

OFF

3.9 Connecting the Load

Turn off the AC input power before making or changing any rear panel connection. Ensure that
all connections are securely tightened before applying power. There is a potential shock hazard
when using a power supply with a rated output greater than 60VDC.

”.

WARNING:

There is a potential shock hazard when using a power supply with an output voltage greater than
60VDC. Turn off the AC input power before making or changing any rear panel connection.
Ensure that the protection of output bus-bars and output connectors is mounted and properly
assembled when output voltage exceed 60VDC. Ensure that all connections are securely tightened
before applying power.

WARNUNG:

Bei Einsatz einer Stromversorgung von über 60VDC Nennspannung besteht eine potentielle
Gesundheitsgefahr durch elektrischen Schlag. Schalten Sie die Stromversorgung AUS, bevor Sie Anschlüsse
auf der Rückseite vornehmen oder verändern. Stellen Sie sicher, dass die Schutzabdeckungen der
Ausgangs-Stromschienen und Ausgangsstecker zuverlässig montiert sind, wenn die Ausgangsspannung
60VDC übersteigt. Stellen Sie sicher, dass alle Verbindungen fest angezogen sind, bevor Sie das Gerät
mit Netzspannung verbinden.

3.9.1 Load Wiring

The following considerations should be made to select wiring for connecting the load to the
power supply:

• Current carrying capacity of the wire (refer to 3.9.2)

• Insulation rating of the wire should be at least equivalent to the maximum output voltage
of the power supply.

• Maximum wire length and voltage drop (refer to 3.9.2)

• Noise and impedance effects of the load wiring (refer to 3.9.4).

39

3.9.2 Current Carrying Capacity

Two factors must be considered when selecting the wire size:

1. Wires should be at least heavy enough not to overheat while carrying the power supply load
current at the rated load, or the current that would flow in the event the load wires were
shorted, whichever is greater.

2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated
current. Although units will compensate higher voltage drop in each load wire (refer to the
specifications). It is recommended to minimize the voltage drop (1V maximum) to prevent
excessive output power consumption from the power supply and poor dynamic response
to load changes. Please refer to Tables 3-2 and 3-3 for maximum wire length to limit voltage
drop in American and European dimensions respectively.

Where current is expressed in amperes and resistivity in ohms/km or ohms/1000ft.

40

3.9.3 Wire Termination

The wires should be properly terminated with terminals securely attached. DO NOT use non
terminated wires for load connection at the power supply.

CAUTION:

When local sensing, a short from +LS or +S to -V or -S or -LS, will cause damage to the power supply.
Reversing the sense wires might cause damage to the power supply in local and remote sensing.
(Do not connect -S to +V or +S to -V.)

3.9.4 Noise and Impedance Effects

To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted
pairs to the shortest possible length. Shielding of sense leads may be necessary in high noise
environments. Where shielding is used, connect the shield to the chassis via a rear panel Ground
screw. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to
reduce coupling, which might impact the stability of power supply. The sense leads should be
separated from the power leads.

Twisting the load wires reduces the parasitic inductance of the cable which could produce high
frequency voltage spikes at the load and the output of power supply, because of current variation
in the load itself.
The impedance introduced between the power supply output and the load could make the ripple
and noise at the load worse than the noise at the power supply rear panel output. Additional
filtering with bypass capacitors at the load terminals may be required to bypass the high frequency
load current.

3.9.5 Inductive Loads

Inductive loads can produce voltage spikes that may be harmful to the power supply. A diode
should be connected across the output. The diode voltage and current rating should be greater
than the power supply maximum output voltage and current rating. Connect the cathode to the
positive output and the anode to the negative output of the power supply.
Where positive load transients such as back EMF from a motor may occur, connect a surge suppressor
across the output to protect the power supply. The breakdown voltage rating of the suppressor
must be approximately 10% higher than the maximum output voltage of the power supply.

3.9.6 Making the Load Connections

WARNING:

There is a potential shock hazard when using a power supply with an output voltage greater than
60VDC. To protect personnel against accidental contact with hazardous voltages, ensure that the
protection of output bus-bars and output connectors is mounted and properly assembled. Ensure
that the load and its connections have no accessible live parts. Ensure that the load wiring insulation
rating is greater than or equal to the maximum output voltage of the power supply.

WARNUNG:

Bei Einsatz einer Stromversorgung von über 60VDC Nennspannung besteht eine potentielle
Gesundheitsgefahr durch elektrischen Schlag. Stellen Sie sicher, dass die Schutzabdeckungen der
Ausgangs-Stromschienen und Ausgangsstecker zuverlässig montiert sind, um Anwender vor einem
unbeabsichtigten Kontakt mit gefährlicher Spannung zu schützen. Stellen Sie sicher, dass keine
spannungsführenden Teile an der Last und ihren Anschlüssen berührt werden können. Stellen Sie
sicher, dass die Isolatiosspannung der Lastleitungen mindestens gleich oder größer als die maximale
Ausgangsspannung der Stromversorgung ist.

41

CAUTION:

Ensure that the load wiring mounting hardware does not short the output terminals. Heavy connecting
cables must have some form of strain relief to prevent loosening the connections or bending the
bus-bars.

10V to 100V Models

Refer to Fig.3-4 for connection of the load wires to the power supply bus-bars and to Fig.3-5 for
mounting the bus-bars shield to the chassis.

and output connectors protection assembled.
Ensure that the protection of output bus-bars and output connectors is mounted and properly assembled,
and that the bus bar protection is locked by two PT type screws as described in Fig. 3.5

WARNUNG:

Bei Einsatz einer Stromversorgung von über 60VDC Nennspannung besteht eine potentielle
Gesundheitsgefahr durch elektrischen Schlag. Schalten Sie keine Stromversorgung mit
einer Ausgangsspannung von über 60VDC EIN, ohne dass die Schutzabdeckungen der
Ausgangsstecker oder Ausgangs-Stromschienen montiert sind. Stellen Sie sicher, dass die
Schutzabdeckungen des Ausgangssteckers bzw. der Ausgangs-Stromschienen fachgerecht
montiert wurden und wie in Bild 3.5. dargestellt mit 2 PT-Typ Schrauben gesichert sind.

3.9.7 Connecting Single Loads, Local Sensing (default)

3.9.8 Connecting Single Loads, Remote Sensing

Fig.3-7 shows recommended remote sensing connection for single loads. Remote sensing is
used when, in Constant Voltage mode, the load regulation is important at the load terminals. Use
twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should
be connected to the ground at one point, either at the power supply chassis or the load ground.
The optimal point for the shield ground should be determined by experimentation.

3.9.9 Connecting Multiple Loads, Radial Distribution Method

Fig.3-8 shows multiple loads connected to one supply. Each load should be connected to the
power supply’s output terminals using separate pairs of wires. It is recommended that each pair of
wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation.
The sense wires should be connected to the power supply output terminals or to the load with
the most critical load regulation requirement.

If remotely located output distribution terminals are used, the power supply output terminals
should be connected to the distribution terminals by a pair of twisted and/or shielded wires. Each
load should be separately connected to the remote distribution terminals (see Fig.3-9).
If remote sensing is required, the sensing wires should be connected to the distribution terminals
or at the most critical load.

3.9.11 Grounding Outputs

Either the positive or negative output terminals can be grounded. To avoid noise problems caused
by common-mode current flowing from the load to ground, it is recommended to ground the
output terminal as close as possible to the power supply chassis ground.

Always use two wires to connect the load to the power supply regardless of how the system is
grounded.

WARNING:

The power supllies shall not float outputs more than +/- 100VDC above/below chassis ground.

WARNUNG:

Die Ausgänge der Netzgeräte dürfen nicht mit einen Potentialunterschied zur Gehäuse - Erdung von
mehr als +/- 100VDC betrieben werden.

3.10 Local and Remote Sensing

The rear panel J2 sense connector is used to configure the power supply for local or remote sensing
of the output voltage. Refer to Fig.3-10 for sense connector location.

3.10.1 Sense Wiring

WARNING:

There is a potential shock hazard at the sense connector when using a power supply with an output
voltage greater than 60VDC. Local sense and remote sense wires should have a minimum insulation
rating equivalent or greater than the maximum output voltage of the power supply. Ensure that the
connections at the load end are shielded to prevent accidental contact with hazardous voltages.

WARNUNG:

Bei Stromversorgungen mit einer Ausgangsspannung von über 60VDC besteht an den Sense-Anschlüssen
die Gefahr eines elektrischen Schlags. Die Senseleitungen sollten mit einer Isolationsspannung
klassifiziert sein, die höher als die maximale Ausgangsspannung der Stromversorgung ist. Stellen Sie
sicher, dass die Anschlüsse an der Last abgedeckt sind, um versehentlichen Kontakt mit gefährlichen
Spannungen zu verhindern.

45

3.10.2 Local Sensing

The power supply is shipped with the rear panel J2 sense connector wired for local sensing of
the output voltage. Refer to Table 3-4 for J2 terminals assignment. With local sensing, the output
voltage regulation is made at the output terminals. This method does not compensate for voltage
drop on the load wires, therefore it is recommended only for low load current applications or
where the load regulation is less critical.

Fig.3-10: Sense connector location

Terminal Function

J2-1 Local negative sense. Connected internally to the negative output terminal (-LS).
J2-2 Remote negative sense (-S).
J2-3 Remote positive sense (+S).

J2-4 Local positive sense. Connected internally to the positive output terminal (+LS).

Table 3-4: J2 terminals

3.10.3 Remote Sensing

WARNING:

There is a potential shock hazard at the sense point when using power supply with an output voltage
greater than 60VDC. Ensure that the connections at the load end are shielded to prevent accidental
contact with hazardous voltages.

WARNUNG:

Bei Einsatz einer Stromversorgung mit einer Ausgangsspannung von über 60VDC besteht am lastseitigen
Sense-Punkt die potentielle Gefahr eines elektrischen Schlags. Stellen Sie sicher, dass die Anschlüsse
an der Last abgedeckt sind, um versehentlichen Kontakt mit gefährlicher Spannung zu vermeiden.

WARNING:

Do not operate the Power Supply with remote sense wire connected to the load without connecting
load wire to the output terminal. Make sure that the connection is reliable to avoid disconnection
during operation. Disconection may cause damage to the power supply.

WARNUNG:

Betreiben Sie die Stromversorgung niemals mit zur Last angeschlossenen Senseleitungen, wenn
nicht gleichzeitig auch die Lastleitungen angeschlossen sind. Stellen Sie sicher, dass die Leitungen
fest verbunden sind, um eine Unterbrechung im Betrieb zu verhindern. Eine Unterbrechung kann
zu Schäden an der Stromversorgung führen.

46

CAUTION:

When using shielded sense wires, ground the shield in one place only. The location can be the power
supply chassis or one of the output terminals.

Use remote sense where the load regulation at the load end is critical. In remote sense, the power
supply will compensate for voltage drop on the load wires. Refer to the specifications for the
maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage available
at the output. Follow the instructions below to configure the power supply for remote sensing:

1. Ensure that the AC On/Off is in the Off position.

2. Remove the local sense jumpers from J2.

3. Connect the negative sense lead to terminal J2-2 (-S) and the positive sense lead to terminal
J2-3(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely
into the rear panel sense connector, J2.

4. Turn On the power supply.

NOTES:

1. If the power supply is operating in remote sense and either the positive or negative load wire
is not connected, an internal protection circuit will activate and shut down the power supply.
To resume operation, turn the AC On/Off to the Off position, connect the open load wire, and
turn On the power supply.

2. If the power supply is operated without the remote sense lines or local sense jumpers, it will
continue to work, but the output voltage regulation will be degraded. Also, the OVP circuit
may activate and shut down the power supply.

CHAPTER 5: LOCAL OPERATION

5.1 Introduction

This Chapter describes the operating modes that do not require programming and monitoring the
power supply via its communication interface. USB or RS232/RS485 or by remote analog signals.
Ensure that the REM LED on the front panel is Off, (indicating Local mode). If the REM LED is On,
press the front panel REM button to change the operating mode to local.

- For information regarding remote analog programming refer to Chapter 6.

- For information regarding usage of the serial communication port refer to Chapter 7.

5.2 Standard Operation

The power supply has two basic operating modes: Constant Voltage mode and Constant Current
mode. The mode in which the power supply operates at any given time depends on the output
voltage setting, output current limit setting and the load resistance.

5.2.1 Constant Voltage Mode and Voltage Setting

1. In constant voltage mode, the power supply regulates the output voltage at the selected
value, while the load current varies as required by the load.

2. While the power supply operates in constant voltage mode, the CV LED on the front panel
illuminates.

3. Adjustment of the output voltage can be made when the power supply output is enabled
(Output On) or disabled (Output Off). When the output is enabled, simply rotate the Voltage
encoder knob to program the output voltage. When the output is disabled, press the PREV
button and then rotate the Voltage encoder to required value. The Voltage display will show
the programmed output voltage for 5 seconds. Then ”OFF” will appear on the Vol tage d ispl ay.

4. Resolution can be set to Coarse or Fine adjustment. Press FINE button to select between the
lower and higher resolution. The FINE LED illuminates when the resolution is set to Fine.

NOTE:

If after completing the adjustment, the display shows a different value than the setting, the power
supply may be at current limit. Check the load condition and the power supply current limit setting.

NOTE:

The maximum and minimum setting values of the output voltage are limited by the Over Voltage
protection and Under Voltage limit setting. Refer to sections 5.3.2 and 5.3.3 for more details.

5.2.2 Constant Current Mode and Current Setting

1. In constant current mode, the power supply regulates the output current at the selected value, while
the voltage varies with the load requirement.

2. While the power supply is operating in Constant Current mode, the CC LED illuminates.

3. Adjustment of the output current can be made when the power supply output is enabled
(Output On) or disabled (Output Off). When the output is enabled, simply rotate the Current
encoder knob to program the output current. When the output is disabled, press the PREV
button and then rotate the Current encoder to required value. The Current display will show
the programmed output current for 5 seconds. Then ”OFF” will appear on the Vol tage displ ay.

4. Resolution can be set to Coarse or Fine adjustment. Press the FINE button to select between the
Coarse and Fine adjustment. The FINE LED illuminates when the resolution is set to Fine.

58

5.2.3 Automatic Crossover

When the power supply operates in Constant Voltage mode, while the load current is increased
to greater than the current limit setting, the power supply will automatically switch to Constant
Current mode. If the load is decreased to less than the current limit setting, the power supply will
automatically switch back to Constant Voltage mode.

5.2.4 Output On/Off Control

The Output On/Off enables or disables the power supply output. The Output On/Off can be
activated from the front panel using the OUTPUT button or from the communication interface.
The OUTPUT button can be pressed at any time (except in Front Panel Lock mode or when a Fault
condition exists). When the output is disabled, the output voltage and current fall to zero and the
Voltage display shows ”OFF”. Press the OUTPUT button to recover from Faults such as: OVP, UVP
and FOLD faults, after the Fault conditions have been removed.

5.2.5 Safe Start and Auto-Restart Modes

At turn on, the power supply AC On/Off can start at last setting of Output Voltage and Current
limit with the output enabled (Auto-restart), or it can start with the output disabled (Safe mode).
Press and hold the OUTPUT button to toggle between Safe start and Auto-restart modes. The
Voltage display will continuously cycle between ”SAFE” and ”ATO” every 3 seconds. Releasing
OUTPUT button while one of the modes is displayed, selects that mode. The default setting at
shipment is in Safe mode.

• Automatic Start Mode (ATO)
The power supply is restored to last operation setting. Upon start-up, the output is enabled
or disabled according to the last setting.

• Safe Start Mode (SA FE)

5.3 Alarms and Protective Functions

5.3.1 Introduction

There are several conditions that cause alarm (RED LED blinks). All alarms affect the output. When
an alarm occurs, the respective fault will appear on the display and the alarm LED illuminates. It
is possible that more than one fault (alarm) may be triggered but only the first will be shown on
the display. If the second fault is still active when the first fault is removed, then the second fault
will be displayed.
The following protective functions are incorporated in the power supply:

• OVP - Over Voltage Protection

• UVP - Under Voltage Protection

• ILC - Interlock

• FOLD - Fold Back Constant Current or Constant Voltage

• AC FAIL - AC Power shut down

• OTP - Over Temperature Protection

5.3.2 Over Voltage Protection

The OVP circuit protects the load in the event of a remote or local programming error or a power
supply failure. The protection circuit monitors the voltage at the power supply sense points thus
providing the protection level at the load. Upon detection of an Over Voltage condition, the power
supply output will shut down.

5.3.2.1 Setting the OVP Level

The OVP can be set when the power supply output is Enabled (On) or Disabled (Off ). The minimum
setting level is 5% above the output voltage, or the value in Table 5-1, whichever is higher.
The maximum setting level is shown in Table 5-1.

1. Press PROT button. PROT (GREEN) LED illuminates. ”O” message appears on the Voltage
display.

2. Press Voltage encoder. ”O” message appears on the Voltage display and the Current display

• Press OUTPUT button.

• AC recycle.

• On/Off recycle by analog control (Interlock).

• Send communication command to enable output.

5.3.3 Under Voltage Protection and Under Voltage Limit

The UVL function prevents output voltage setting below UVL set value. The UVP function prevents
power supply operation if output voltage is below UVP set value. Upon detection of an Under
Voltage condition, the power supply output will shut down. The UVL prevents adjustment of the
output voltage below a certain limit. The combination of UVP/UVL and OVP functions, allows the
user to create a protection window for sensitive load circuitry.

5.3.3.1 Setting the UVP/UVL Mode and Level

The UVP/UVL can be set when the power supply output is Enabled (On) or Disabled (Off ). UVL
and UVP setting values are limited at the maximum level to approximately 5% below the Output
Voltage setting. Attempting to adjust the value above this limit will result in no response to the

adjustment attempt. The minimum value setting is zero. If UVP setting is below 5% of rated output
voltage, UVP will act as UVL. When UVP is selected, UVL will be disabled and Vice Versa.

5.4 Series Operation

Power supplies of the same model can be connected in series to obtain increased output voltage.
Split connection of the power supplies gives positive and negative output voltage.

WARNING:

When power supplies are connected in series, and the load or one of the output terminals is grounded,
no point may be at a greater potential of +/- 100VDC from ground.

WARNUNG:

Bei Reihenschaltung mehrerer Geräte und Verbindung der Last bz w. eines Ausgangspoles mit System­Masse, sollte kein Potential von über +/- 100VDC zwischen Ausgang und System-Masse anliegen.

5.4.1 Series Connection for Increased Output Voltage

Two units are connected so that their outputs are summed. Set the current limit of each power
supply to the maximum that the load can handle without damage. It is recommended that diodes
be connected in parallel with each unit output to prevent reverse voltage during start up sequence
or in case one of the units shuts down. Each diode should be rated to at least the power supply
rated output voltage and output current. Refer to Fig.5-1 and Fig.5-2 for series operation with
local and remote sensing.

5.4.3 Remote Programming in Series Operation

Programming by external voltage: The analog programming circuits of this power supply are referenced

to the negative Sense potential. Therefore, the circuits used to control
each series connected unit must be separated and floated from each
other. Refer to section 6.4

Using the SO function and PS_OK signal : The Shut Off and PS_OK circuits are referenced to the isolated interface

common, IFC_COM (J3-7). The IFC_COM terminals of the units can be
connected to obtain a single control circuit for the power supplies
connected in series.

Programming by external resistor : Programming by external resistor is possible. Refer to section 6.5 for

details.

Programming via the Serial Communication
port (RS232/RS485, USB):

The Communication port is referenced to the IFC_COM which is
isolated from the power supply output potential. Therefore power
supplies connected in series can be chained using the Remote-In and
Remote-Out connectors. Refer to Chapter 7 for details.

64

5.5 Parallel Operation

5.5.1 Introduction

Up to six units of the same Voltage and Current rating can be connected in parallel to provide up
to six times the output current capability. One of the units operates as a master and the remaining
units are slaves. The slave units are analog programmed by the master unit. In remote digital
operation, only the master unit can be programmed by the computer while the slave units may
be connected to the computer for voltage, current and status readback only.

The Master and Slave modes are stored in the power supply EEPROM when the AC power is turned
off. The system will return to the Master/Slave mode upon re-application of AC power.
There are two methods to configure multiple supplies for parallel operation (basic and advanced).
Refer to Section 5.5.2 and to Section 5.5.3 for detailed explanation. Parallel modes are selected
via Front Panel menu. Refer to table 5-2.

5.5.2 Basic Parallel Operation

In this method, setting the units as Master and Slaves is made by the rear panel J1 connections
and setup via Front Panel. Each unit displays its own output current and voltage. To program the
load current, the Master unit should be programmed to the total load current divided by the
number of units in the system. The master and slave units operate in a Daisy-Chain connection
configuration. For further details about Daisy-chain connection refer to section 5.6. Refer to the
following procedure to configure multiple supplies for basic parallel operation.

5.5.2.1 Master Unit Set Up

During operation, the master unit operates in CV mode, regulating the load voltage at the
programmed output voltage. Connect the sensing circuit to local or remote sensing as shown in
Fig.5-4 or Fig.5-5. Front Panel Main Menu Parallel mode is ”H1” as default.

1. Press MENU button.

2. Rotate Voltage encoder until ”r” appears on Voltage display, then press Voltage encoder.

3. Rotate Current encoder until ”H1 ” appears.
Press Current encoder to select ”H1 ”, the display blinks once and returns to previous menu level.

4.

5. Set the master unit output voltage to the desired voltage. Program the current limit to the
desired load current limit, divided by the number of parallel units.

6. If there is more than one Slave unit connected to the Master, then set the PS_OK signal delay
of the Master to 200msec. Refer to section 5.7.4 Power Supply OK Signal.

65

5.5.2.2 Slave Unit Set Up

When Slave mode is selected the power supply enters Current programming mode via external
Voltage. Voltage and Current programming setting values are set to 105% of range. During operation
the slave units operate as a controlled current source following the master output current. It is
recommended that the power system is designed so that each unit supplies up to 95% of its current
rating. This helps reduce imbalance which may occur by cabling and connections voltage drop.

1. Press MENU button

2. Rotate Voltage encoder until ”r” appears on Voltage display, then press Voltage encoder.

3. Rotate Current encoder until ”S” appears.

4. Press Current encoder to select ”S”. Display blinks once and returns to previous display.

5. For wiring instructions, refer to Fig.5-4: Parallel connection with local sensing or Fig.5-5:
Parallel connection with remote sensing.

5.5.2.3 Setting Over Voltage Protection

The master unit OVP should be programmed to the desired OVP level. In slave mode, the power
supply is set to maximum as default.

5.5.2.4 Setting Foldback Protection

Foldback protection, if desired, may only be used with the master unit. When the master unit shuts
down it programs the slave units to zero output voltage.

5.5.2.5 Connection to Load

In parallel operation, power supplies can be connected in local or remote sensing. Refer to Fig.5-4
and 5-5 for typical connections of parallel power supplies. The figures show connection of two
units, however the same connection method applies for up to 6 units.

Fig.5-4: Parallel connection with local sensing

66

Fig.5-5: Parallel operation with remote sensing

CAUTION:

Make sure that the connection between - Vo terminals is reliable to avoid disconnection during
operation. Disconnection may cause damage to the power supply.

NOTE:

With local sensing it is important to minimize the wire length and resistance. Also the positive and
negative wire resistance should be as close as possible to each other to achieve current balance
between power supplies.

67

5.5.3 Advanced Parallel Operation

5.6 Daisy-Chain Connection

It is possible to configure a multiple power supply system to shut down all units when a fault
condition occurs in one of the units. When the fault is removed, the system recovers according to
a preset state: Safe start mode or Automatic restart.

Set signal ”SO” to positive logic via Front panel (refer to section 5.7.1) . If a fault occurs in one of
the units it’s ”PS_OK” signal will be set to low level and the display will indicate the fault. The other
units will shut off and their displays will indicate ”SO”. When the fault condition is removed, the
units will recover to their last setting according to their respective Safe start or Auto-restart setting.

Fig.5-6 shows connection of three units, however the same connection method applies to systems
with more units.

5.7.1 External Shut Off Function

SO signal serves as Output Shut Off . It is an optically isolated signal from the power supply output.
Connection to the signal is made via pin J3-5 (Shut Off ) and pin J3-7 (IFC_COM). The SO pin accepts
a 4V to 15V signal or Open-Short contact to disable or enable the power supply output. The SO
function will be activated only when a transition from On to Off is detected after applying AC
power to the unit. Thus, in Auto start mode, the output will be enabled after applying AC power,
even if SO is in Off level. After On to Off transition is detected, the SO will enable or disable the
power supply output according to the signal level or the short/open applied to J3. When the
external SO is triggered, the power supply will display ”SO”on the voltage display but the PROT
LED will not illuminate.

The external shutdown is useful when using the power supply as part of a larger test system in
which digital or analog control is required or in ”Daisy-Chain”.
The SO control logic can be selected via the Front panel as follows:

1. Press MENU button. MENU (GREEN) LED illuminates. ”set” message appears on the Voltage

7.7.1 Data Format

Serial data format is 8 bit, one start bit and one stop bit. No parity bit.

7.7.2 End of Message

The end of message is the Carriage Return character (ASCII 13, 0x0D). The power supply ignores
the Line Feed (ASCII 10, 0x0A) character.

7.7.3 Command Repeat

The backslash character ”\” will cause the last command to be repeated.

7.7.4 Checksum

The user may optionally add a checksum to the end of the command. The checksum is ”$” followed
by two hex characters. If a command or a query has checksum, the response will also have one.
There is no CR between the command string and the ”$” sign. Example: STT?$3A STAT?$7B

7.7.5 Acknowledge

The power supply acknowledges received commands by returning ”OK” message. If an error is
detected, the power supply will return an error message. The rules for checksum also apply to
the acknowledge feature.

7.10.4 Checksum

The user may optionally add a checksum to the end of the command. The checksum is ”$” followed
by two hex characters. If a command or a query has checksum, the response will also have one.
There is no CR between the command string and the ”$” sign.

7.10.5 SCPI Requirements

The power supply conforms to the following SCPI requirements:

1. SCPI common commands.

2. SCPI Command Tree.
3 Subsystem commands.

4. The ROOT level.

5. The power supply is powered On

6. A device clear (DCL) is sent to the power supply

7. The SCPI interface encounters a root specifier (:)

8. Questionable Status Register (QSR), Condition, Event, Enable

9. Operation Status Register (OSR), Condition, Event, Enable

10. Status Byte Register (SBR)

11. Standard Event Status Register (SESR)

12. Using the MIN and MAX Parameters.

13. Suffix and Multipliers.

14. Boolean data. 1 | 0 or ON | OFF

7.10.6 SCPI Command Hierarchy

SCPI is an ASCII-based command language designed for use in test and measurement equipment.
The command structure is organized around common roots, or nodes, which are the building
blocks of SCPI subsystems. An example of a common root is OUTPut, and some of the commands
that reside in the OUTPut subsystem are:

OUTPut
[:STATe]<bool>
:PON
[:STATe]<bool>
:PROTection
:CLEar
:FOLDback
[:MODE]
A colon (:) is used to separate a command keyword from a lower-level keyword.

7.10.7 Header

Headers are instructions recognized by the power supply. Headers (which are sometimes known
as ”keywords”) may be either in long or short form.

Long form The header is completely spelled out, such as VOLTAGE, STATUS, and DELAY
Short form The header has only the first three or four letters, such as VOLT, STAT, and DEL.

The SCPI interface is not sensitive to case. It will recognize any case mixture, such as TRIGGER,
Trigger, TRIGger. Short form headers result in faster program execution.

7.12 SCPI Subsystem Commands

Subsystem commands are specific to power supply functions. They can be a single command
or a group of commands. Groups are comprised of commands that extend one or more levels
below the root.
Commands followed by a question mark (?) take only the query form. Except as noted in the syntax
descriptions, all other commands take both the command and query form.

7.12.1 Output Subsystem

OUTPut

This command enables or disables the power supply output. When output is turned off, voltage
display shows ”OFF”.

SCPI Command Syntax OUTPut[:STATe] <bool>
GEN Command Syntax OUT <bool>
Parameters 0|OFF 1|ON
*RST Value OFF
Examples OUTP 1 OUTP:STAT ON
Query Syntax OUTPut[:STATe]?
Returned Parameters 0|1

OUTPut:PON[:STATe]

• AUTO - The power supply output will return to its previous value when the latching fault
condition is removed or to the stored value after AC recycle.

• SAFE - The power supply output will remain Off after the fault condition is removed or after
AC recycle.

SCPI Command Syntax OUTPut:PON[:STATe] <bool>
GEN Command Syntax AST <bool>
Parameters 0|OFF 1|ON
*RST Value OFF
Examples OUTPut:PON 1
Query Syntax OUTPut:PON[:STATe]?
Returned Parameters 0|1

OUTPut:PROTection:CLEar

This command clears the latch that disables the output when an over voltage (OVP), under voltage
(UVP), or foldback (FOLD) fault condition is detected. All conditions that generate a fault must
be removed before the latch can be cleared. The output is then restored to the state before the
fault condition occurred.

SCPI Command Syntax OUTPut:PROTection:CLEar
GEN Command Syntax None
Parameters None

OUTPut:PROTection:FOLDback

Foldback mode is used to disable the output when a transition is made between the operation
modes. The power supply will turn off the output after a specified delay if the power supply makes
transition into CV mode or into CC mode. This feature is particularly useful for protecting current
or voltage sensitive loads.

SCPI Command Syntax OUTPut:PROT:FOLDback[:MODE] <CRD>
GEN Command Syntax FLD <CRD>
Parameters OFF|0, CC|1, CV|2 .
*RST Value OFF
Examples OUTPut:PROT:FOLDback[:MODE] CC
Query Syntax OUTPut:PROT:FOLDback[:MODE]?
Returned Parameters <CRD>

OUTPut:PROTection:DELay

Sets the delay time between the programming of an output change that produces a CV or CC
status condition. This command applies to UVP and Foldback functions.

SCPI Command Syntax OUTPut:PROTection:DELay <NRf+>
GEN Command Syntax FBD
Parameters 0.1 to 25.5|MIN|MAX (step 0.1s)
Unit S (second)
*RST Value 0mS
Examples OUTPut:PROTection:DELay 2E-1
Query Syntax OUTPut:PROTection:DELay?
Returned Parameters <NR3>

OUTPut:ILC:MODE

Selects the mode of operation of the Remote Inhibit protection. In OFF mode the power supply
ignores J3-4 (ILC) status.

SCPI Command Syntax OUTPut:ILC:MODE <CRD>
GEN Command Syntax RIE
Parameters 0|OFF 1|ON
*RST Value OFF
Examples OUTPut:ILC:MODE ON
Query Syntax OUTPut:ILC:MODE?
Returned Parameters ON/OFF
