CHAPTER 3 INSTALLATION

3.1 GENERAL

This chapter contains instructions for initial inspection, preparation for use and repackaging for shipment. Connection to PC, linkingZUP units and setting the address are describedin chapter 5.

NOTE

ZUP series power supplies generate a magnetic field which might affect the

operation of other instruments. If your equipment is susceptible to magnetic fields,

do not position adjacent to the ZUP.

3.2 INITIAL INSPECTION

Prior to shipment this power supply was inspected and found free of mechanical or electrical defects. Upon unpacking of the power supply, inspect for any damage which may have occurred in transit. Keep all packing materials until inspection has been completed. If any damage is detected, file a claim with the carrier immediately and notifythe Nemic-Lambda sales or service facility nearest you.

3.2.1 Mechanical inspection

The mechanical inspectionshould confirm that there isno exterior damage to the power supply suchas broken knobs or connectors andthat the front panel and meterface are not scratched or cracked.

3.2.2 Preparation for use

In order to be operational the power supply must be connected to an appropriate AC source. The line voltage must be within the power supply specification. DO NOT apply power before reading paragraph

3.3.

3.3 AC SOURCE REQUIREMENTS

The ZUP series can be operated from a nominal 100V to 240V, single phase, 47 ~ 63Hz. The input voltage range and current required for each model is specified in chapter 2. Make sure that under heavy load, the AC voltage supplied to the power supply does notfall below “low limit” specifications.

3.4 COOLING & PLACEMENT

This power supply is fan cooled. Upon installation ensure sufficient space for air intake (front panel) and exhaust (rear panel). The power supply should be used in an area where the ambient temperature

does not exceed +50 C

3.5 RACK MOUNTING

ZUP models can be mounted in a standard 19” rack (3U height). The 200W and 400W models occupy 1/6 rack length. The 800W model occupies 1/3 rack length. The power supplies should be fixed by M4 screws replacing the rubber feet on the bottom of the power supply. The screws must not protrude more than 6mm into the powersupply. Refer to the outline drawingin this chapter for mounting details.

3.6 POWER CONNECTION

Connection of this power supply to an AC power source should

be made by an electrician or other qualified personnel.

CAUTION

This power supply is equipped with a three conductor power cable. The third conductor is the ground conductor. When the cable is plugged-in to an appropriate receptacle, the power supply is grounded. Under no circumstances should this power supply be operated without an adequate ground connection. If a two contact receptacle is encountered, it must be replaced by a three contact receptacle, properly grounded. This operation should be done by a qualified electrician. It is recommended to keep the AC input wires separate from the DC output and signal wires to avoid interference. To meet radiated EMI specification, the EMI suppressor clamp should be attached to the AC cable as close as possible to theAC inletof the power supply.

WARNING

Some components inside the power supply are at AC voltage even when the

On/Off switch is in the “Off” position. To avoid the hazard of electric shock,

disconnect line cord and load and wait 2 minutes before removing cover.

3.7 CONNECTING THE LOAD

WARNING

Turn off the AC input power before making or changing any rear panel connection. Make sure 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 40V. Use load wiring with a minimum insulation rating equivalent to the maximum output voltage of the power supply.

3.7.1 Selecting wire size

Twofactors must be considered in selecting wire size.

1. Wires should be at least heavy enough to avoid overheating while carrying the power supply load current at the rated load, or the current that would flow in the event the load wire were shorted, whichever is greater.

2. Wire size should be selected to enable voltagedrop per leadto be less than 0.5V at the rated current. It is recommended to minimize voltage drop on the wires to prevent excessive output power consumption from the power supply. Please refer to Tables 3-1 and 3-2 for maximum wire length to limit voltage drop by American and European measurements respectively.

3.7.2 Wire termination

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

CAUTION

At local sensing, short between +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

at local and remote sensing.

3.7.3 Single load connection, Local Sensing

Fig. 3-1 illustrates the connection of a single load to the power supply using local sensing. This connection is made via the “External Control Connector” located on the rear panel of the power supply. Local sensing is suitable for applications where load regulation is not critical.

3.7.4 Single load connection, Remote Sensing

Remote Sensing is used in cases where, 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 the power supply chassis or the load ground. The optimal point for the shield ground should be determined by experimentation. At Remote Sensing, the maximum voltage drop allowed at the load wires is 0.5V per wire for 6V to 60V models and 2V per wire for 80V and 120V models.

3.7.5 Multiple load connections, radial distribution method

In cases of 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 recommendedthat 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.

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

WARNING

The maximum potential (including output voltage) that either output terminal is from ground, must not exceed the specified voltage on the front panel.

3.8 EXTERNAL CONTROL CONNECTOR

3.8.1 General

The external control connector, used for analog programming of the power supply, is located on the rear panel of the unit,(Fig. 4-2, item 4). The pin assignmentis shown in Fig. 3-5 below.

WARNING

The External Control Connector signals are connected to the negative output terminal. If the negative output terminal is floated with respectto chassis ground , thosesignals will also float at the same potential. Use appropriate safety measures to prevent a shock hazard.

4.4 LOCAL OPERATION

4.4.1 Introduction

This paragraph describes the operating modes not involved in programming the power supply via it’s serial communication port. Operation utilizing the front and rear panel are described in this paragraph. For information regarding serial portusage, please refer to chapter 5. The REM LED on the front panel indicates whether the power supply is in Local or Remote mode. The extinguished LED indicates Local operation. If the LED illuminates, the REM pushbutton (fig.4-1, item

8),should be pressed to changethe operating mode to Local.

4.4.2 Constant Voltage Operation

1. In constant voltage mode, the power supply maintains the output voltage at the selected value while the load current varies asrequired by the load.

2. While the power supplyis operating at constant voltage, the CV LEDon the front panel illuminates.

3. For coarse output voltage adjustment, press V/A consecutively, until the V LED illuminates, and

the VOLTS display shows FA_V. The AMPS display will show the output voltage setting value. Rotate the ADJUST knob to set the output voltage. At this mode, approx. 6 turns are required to adjust the entire range. Approx. 3sec after the adjustment, the display returns to show the actual voltage and current.

4. For fine adjustment ofoutput voltage, press V/Aconsecutively untilthe V LED illuminates and the VOLTS displayshows SL_V. The AMPS display willshow the output voltage setting value.Rotate theADJUST knob to setthe output voltage.At this mode the adjustment resolutionis maximal.

Approx 3sec. after the adjustment, the display returns toshow the actual voltage and current.

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 and

under voltage protection settings. Refer to par. 4.4.5 and 4.4.6 for details.

4.4.3 Constant Current Operation

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

2. While the power supplyis operating at constant current, theCC LED on the front panel illuminates.

3. For coarse output currentadjustment, press V/Aconsecutively, until the A LED illuminates, and the VOLTS display shows FA_A. The AMPS display will show the output current setting value. Rotate the ADJUST knob to set the output current. At this mode, approx. 6 turns are required to adjust the entire range. Approx. 3sec after the adjustment, the display returns to show the actual voltage and current.

4. For fine adjustment ofoutput current, press V/A consecutively until the A LED illuminates and the

VOLTS displayshows SL_A. The AMPS display will show the outputcurrent setting value. Rotate theADJUST knob to setthe output current.At this mode theadjustment resolution is maximal.

Approx 3sec. after the adjustment, the display returns toshow the actual voltage and current.

4.4.4 Automatic Crossover

If 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.

4.4.5 Over Voltage Protection (OVP)

1.The OVP circuit monitors the voltage at the power supply sensingpoints thus guaranteeing the

protection level at the load.Upon detection of Over Voltage condition, the power supply will shut down. To resume operation, thepower switch should be turned off for approx. 30sec. Prior to turn-on, check carefully that the sensewires are connected correctly and secured.

2. OVP setting values are limited at the minimumand maximum levels.At minimum level, the OVP level

is limited by the OutputVoltage setting, therefore the OVP level cannot be adjusted below the Output Voltage.At maximum level, the OVP level is limitedto the values shown in Table 4-1.

MODEL (by output voltage) 6V

Maximum OVP

Table 4-1: MaximumOVP setting levels.

3.For over voltage protection adjustment, press OVP/UVP consecutively, until the OVP LED

illuminates and the VOLTS display shows OUP. The AMPS display will show the over voltage protection setting value. Rotate the ADJUST knob to setthe over voltage protection level.Approx. 3sec after the adjustment, the display returns to showthe actual voltage and current.

4. In order to seethe value of the OVP, press OVP/UVP pushbutton, so that the OVP LED illuminates.

At this time the displaywill show the OVP set valuefor approx. 3sec.

5. The minimum over voltage level is approx. 105% of the output voltage set value. Attempting to

adjust the over voltage protection below this value will result in no response to the adjustment attempt.

6. In case the OVP is triggered, the front panel control is disabled unitl the AC input is recycled by

turning the AC ON/OFF switch to OFF and after approx. 30 sec. to ON.

4.4.6 Under Voltage Protection (UVP)

1.The UVP prevents adjustment of theoutput voltage below acertain limit. The combination of UVP

and OVP functions allows the user to create aprotection window for sensitive loads circuitry.

2. For under voltage protection adjustment, press OVP/UVP consecutively until theUVP LED

illuminates and the VOLTS display shows UUP. The AMPS display will show the undervoltage protection setting value. Rotate the ADJUST knob to setthe under voltage protection level.

3. In order to seethe set value of the UVP, press OVP/UVP pushbutton, so that the UVPLED

illuminates.At this time the display will show the UVPset value for approx.3sec.

4. The maximum under voltage level is approx. 95% of theoutput voltage set value.An attemptto

adjust the under voltage protection above this value willresult in no response to the adjustment attempt.

5.The under voltage protection is a software protection only.

4.4.7 Foldback Protection

1. Foldback protection will shutdown the power supply output if the load currentexceeds the current

limit setting level. This protection is useful when theload circuitry is sensitive to over current condition.

2. To arm the Foldbackprotection, the FOLD pushbutton should be pressed so theFOLD LED

illuminates.At this condition transition from Constant Voltage to Constant Current mode willactivate the Foldback protection.

3. Activation of the Foldback protection disables thepower supply’s output, turnson the ALM (alarm)

LED and flashes the FOLDLED.

4. There are 2 modes of releasing an activated Foldback protection.

1. Short press on FOLDpushbutton enables the output and re-arms the protection circuit.If the load is smaller than the current limit level, the power supplywill restore normal operation. If theload is greater than the current limit level, the output will be disabledagain and Foldback indicators will be on.

2. Long press (approx. 3sec)on FOLD pushbutton will disable the Foldback protection circuitand enable the output. The power supply will restore operationto Constant Voltage or Constant Current mode depending on theload characteristics and power supply setting.

4.4.8 Output ON/OFF Control

The ON/OFF circuit has two controls; a front panel pushbutton and a rear panel connection. priority is given to the rear panel connection.

1. Rear panel ON/OFF Control

Contacts 9, 10 at the rear panel External Control connector (fig. 4-2, item 4) serve as ON/OFF terminals. Either short circuit or TTL‘0’level enables the power supply output and open circuit or TTL ‘1’ level disables the power supply’s output. An open collector transistor can be used for the ON/OFF control as shown in fig. 4-3, with sink current ability of more than 2.5mA. Please note that pin 10 (COM) is internally connected to the - Sense potential, therefore for floating ON/OFF Control a photocoupler should be used as shownin Fig. 4-4.

The Front Panel ON/OFF is controlled by the OUT pushbutton.To enable the output, OUT pushbutton should be pressed so thatOUT LED illuminates. The operation ofOUT pushbutton is enabledonly if the rear panel ON/OFF is configured to ‘ON’.

4.4.9 Last Setting Memory

The ZUP series is equipped with Last Setting Memory which stores all power supply parameters at each ac turn-off sequence of the power supply. The OUT parameter storage is determined prior to the ac turn-off to allow two modes of re-start ofthe power supply.

1. Automatic start mode

In this mode the power supply restores it’s last operation setting and sets the OUT to ‘ON’ state. Upon start-up, the output is enabled and the power supply delivers power to the output terminals. To select this mode press and hold OUT pushbutton. After approx. 3sec., the display will continuously cycle between AS ON (auto-start on) and AS OFF (auto-start off), approx. every 3sec. Releasing the OUT pushbutton whileAS ON is displayed, will set the power supply to automatic start mode. (holding OUT depressed for more than 1sec. does not change the output on/off status). In cases where the Over Voltage or Over Temperature or Foldback protection has been activated , the unit will automatically change to safe start mode after theAC voltage recycling.

2. Safe start mode

In this mode,the power supply restores it’s last operation setting and sets theOUT to the ‘OFF’state.To select this mode, press and hold OUT pushbutton. After approx. 3sec., the display will continuously cycle between AS ON (auto-start on) and AS OFF (auto-start off), approx. every 3sec. Releasing the OUT pushbutton while AS OFF is displayed will set the power supply to safe start mode. At startup, the output is disabled and the output voltage and current are zero. To enable the output and restore the last output voltage and current values, OUT pushbutton should be momentarily pressed.

4.4.10 Output Voltage & Current programming by external resistor

1. For resistive programming, internalcurrent sources, for output voltage and/or output current control,

supply 1mA current through external programming resistors. The voltage across the programming resistors is used as aprogramming voltage for thepower supply.Resistance of 0~4kohm programs

the output from 0 tofull scale (full scale is 105% of the ratedvoltage or current).

Avariable resistor can control the output over it’s entire range, ora combination of variable resistor

and series/parallel resistors can control the output over arestricted portion of it’s range.Alternatively, a switch can be usedto select fixed values of programming resistance to obtain a set of discrete voltages or currents. Care must be taken to avoid open circuit at theprogramming resistors, as it will cause over-voltage at the output. In this case, nodamage to the power supply will becaused however,it is recommended to set OVP limit to a level whichis safe for the load circuitry.

2. To maintain the temperature stability specification of the power supply, the resistors used for

programming should be stable and low noise resistors, withtemperature coefficient of lessthan 25ppm and power rating of1/4W or more.

3. Where external resistor programmingis used, front panel control and computer control (via serial

communication) of the output voltage andcurrent are disabled.

4. OUTPUT VOLTAGE PROGRAMMING BY EXTERNAL RESISTOR

Fig 4-5 shows a typical set-up for programming the output voltage. A variable programming resistor, 0~4Kohm produces a proportional output voltage from zero to full scale. In order to set the low limit, a series resistor can be connected to the programming resistor. For example; a 1kohm series resistor will set the lower limit to 25% of full scale. In order to set the upper limit, a resistor can be connected in parallel to the programming resistor. The resultant programming resistance of the series/parallel resistors must be between 0and 4Kohm.

NOTE

Resistive programming is possible for local and remote sensing.

Fig. 4-7 shows the set-up for external voltage programming of the output voltage. A voltage source variable from 0 to 4V, programs the output voltage proportionally from zero to full scale. The static load current on the programming source is less than 2uA. The source resistance should be less than 10Kohm to avoid degradation of offset and drift specifications. When external voltage is used for programming the front panel and the computer control (viathe serial communication) are disabled. Note: Full scale is 105%of the rated output voltage.

or voltage programming, as it may cause the output voltage and current to exceed the power

supply rating. The display will NOT show the actual voltage and current when such resistor

or voltage is applied for programming.

4.4.13 Auto Parallel Operation

1.Up to five units of the same rating canbe connected in an auto-parallel combination to provide up to five times the output currentcapability. One of the power supplies operates asa master and the remaining units as slaves. The slaveunits are analog programmedby the master unit. At remote operation, only the master unitcan be programmed by the computer while the slaveunits may be connected to the computer foractual voltage and currentreadback only.

2. Foldback protection if desired,may only be used with the master unit. Whenthe master unit shuts down it programs the slaveunits to zero outputvoltage.

3. Setting the voltage and current:

The output voltage of the slave units should be programmed higherthan the output and the master to

avoid interference with the masterCV control. Output voltage of themaster should be programmed to the desired voltage, and the current limitto the desired load current divided bythe number of

parallel units. During operation,the master unit operates at CV mode and theslave units at CCmode.

4.While operating in CV mode,the master unit regulates the output voltage and the slave units operate as controlled current source, followingthe master output current. It is recommended to designthe power system so that eachunit will supply up to 95% of it’s current rating, because of animbalance which may be caused bycabling and connections voltage drop.

5. Over Voltage Protection:

OVP of the slave units should be adjusted higher than theMaster OVP. When the master unit shuts down, it programs the slaveunits to zero outputvoltage. If a slaveunit shuts down (whenit’s OVP is set lower than the master output voltage), only that unit will shutdown and remaining slave units will supply all the loadcurrent.

6. Connection to the Load:

4.4.14 Series Operation

1. GENERAL: Two power supplies of thesame rating can be connected in series to increasethe output voltage or to provide bipolar output voltage.

CAUTION

When two power supplies are connected in series, they should be programmed to the same output

voltage to prevent damage to the lower voltage supply at short circuit condition.

2. Series connection for increasedoutput voltage:

2.1 General: At this operation mode, two units are connected so their outputs are summed. Set the

current limits of each power supply to the maximum that the load can handle without damage. It is recommended to connect diodes in parallel to each unit output to prevent reverse voltage during startup condition or in case one of the units shuts down. Each diode should be rated to at least the power supply’s output current. Refer to Fig: 4-12 and 4-13for this operating mode.

CAUTION

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(+or-)from ground than that specified

on the front panel marking.

3. Series connection for bipolaroutput voltage:

3.1 General: At this operation mode, two units are configured as a bipolar voltage/current source. Set the current limits of each power supply to the maximum that the load can handle without damage. It is recommended to connect diodes in parallel to each unit output to prevent reverse voltage during startup condition or in case one of the units shuts down. Each diode should be rated to at least the power supply’s output current. Refer to Fig. 4-14 for thisoperating mode.

4.4.15 Output Good Signal

Output Good Signal is an open collector output, referenced to COM potential, indicating the status of the power supply output. While the power supply operates normally, the Output Good is low (0~0.8V). When the power supply output is disabled due to activated OVP, OTP or FOLD protection, or by OUT set to off, or by ac ON/OFF set to off, then the output signal stops conducting. The maximum sink current is 10mA and the maximum voltage is 40VDC.

CAUTION

The Output Good Signal is referenced to the COM potential, therefore pay attention NOT to

short it to another potential as it may damage the unit.

Typical applications of Output Good Signal

1. In multiple power supplysystems, it is possible to disable all the units whena critical unit fails. Refer to Fig 4-15 for typicalconnection diagram.

For models with output voltage rating greater than 40V use

a Zener diode to limit the Output Good voltage below 40V. The resistor and Zener power rating must be greater than the maximum actual power dissipation.

5.5.4 Status control

5.5.4.1 Registers structure

1. Operational StatusRegister: The operational status register records signals that are part of the power supply’s normal operation. In addition to the normal operation data, the register holds an alarm bit which indicates that one of the alarm (fault) register bits is set. The register is automatically updated and reading it does not change it’s content. Clearing the register is done by DCL command. See table 5-5 for Operational Status Register content.

Bit Name cc/cv fold ast out srf srv

srt alarm

Table 5-5: Operational status register content.

Note: *1 In case of AC fail, the alarm status register ‘AC fail’bitwill be set but will not setthe alarm bit.

Bit No Meaning

‘0’ - Indicates constant voltage, ‘1’ - constant current.

‘1’ - Indicates foldback protection is armed.

2 3

‘1’ - Indicates auto-restart is on, ‘0’ - auto-restart is off. ‘1’ - Indicates output is on , ‘0’ -output is off.

‘0’ - Indicates foldback protection SRQ is disabled , ‘1’ - enabled.

‘0’ - Indicates over voltage protection SRQ is disabled , ‘1’ - enabled.

6 7

‘0’ - Indicates over temp. protection SRQ is disabled , ‘1’ - enabled. ‘1’ - Indicates that an alarm register bit is set. (note*1)

2.Alarm Status Register: The alarm status register records fault conditions occurring during power supply operation. Any set bit in this register causes the ‘alarm’ bit in the operational status register to be set. Reading the register does not change it’s content. The register is cleared by :DCL; command.

Bit Name

‘1’ - Indicates that the over-voltage protection was tripped ‘1’ - Indicates that the over-temperature protection was tripped

‘1’ - Indicates that a failure occurred at the input voltage supply

‘1’ - Indicates that the foldback protection was activated

‘1’ - Indicates a programming error has occurred

(*3) (*3) (*1) (*2) (*3)

Notes: (*1) Since at eachAC turnoff theAC fail bit is generated and stored,it is recommended to

send a :DCL; command followingapplication of AC voltage to the power supply, to clear the

alarm status register. (*2) FOLD bit is automaticallyreset upon cancellation of FOLD protection. (*3) OVP, OTP and ‘prog’ bits reset atAC turn-off or by:DCL; command.

In case the OTP or OVP is triggered, the front panel control is disabled untiltheAC input is recycled by turning the AC ON/OFF switch to OFF andafter approx. 10 sec.to ON.

3. Error Codes Register: The error codes register records errors that occurred during the programming of the power supply. Any set bit in this register causes the ‘prog’ bit in the alarm status register to be set. Reading the register does not change it’s content. The register is cleared by :DCL; command.

Bit Name not used wrong command buffer overflow wrong voltage

5.6 COMMUNICATION PROTOCOL

5.6.1 General Information

The average command processing time of the ZUP Series is 15mSec. It is not recommended to send

strings of commands to theZUP power supply withoutconsidering the processing time.

For query commands (?,!),wait until the ZUP reply message has been completed , before sending a

new command.

5.6.2 Accessing a ZUP Unit

The default condition of the ZUP series is Listen mode. In order to access a ZUP unit, for sending a command or query,the address of that unit should besent by the host controller (:ADRn;). The ZUP that recognizes it’s address becomes active and can communicate with the host controller. The other units remain in Listen mode, waiting to receive their address. To access another unit, the controller should send the address of that unit. The previously active unit changes it’s state to Listen mode and the addressed unit becomes active.

5.6.3 End of Message

The messages generated by theZUP are terminated by an endof message: < CR > carriage returncharacter < LF > line feedcharacter

When sending a message tothe ZUP, there is no need for the endof message characters.

5.7 SERVICE REQUEST

5.7.1 Service Request (SRQ)

Service request is a message generated by the ZUP power supply to interrupt the controller. SRQ can be generated by a power supply fault condition. Each of the following conditions can generate SRQ message:

1. Over Voltage Protection (OVP).

2. Over Temperature Protection (OTP).

3. Foldback Protection. The operator decides which of the conditions are defined as faults. Enabling or disabling a condition from generating SRQ message does not affect the condition within the power supply.

5.7.2 Service Request message

The service request message consists of three characters terminated by EOS<CR><LF>. The first character identifies the SRQ cause: 1-Foldback , 2-OVP , 3-OTP. The 2’nd and 3’rd characters identify the ZUP power supply address.

Example: String generated by a ZUP unit :120<CR><LF> , means foldback protection was activated

in power supply address 20.

5.7.3. Service request enable/disable commands
