1.2.1 General description

1.2.2 Configurations

1.2.4 Output connections

1.2.5 Analog voltage programming

1.2.6 Parallel operation

1.2.3 Control via the serial communication port

This user’s manual contains the operating instructions, installation instructions and specifications of the ZUP series. For information related to operation with GPIB control, refer to Nemic-Lambda GP485 user’s manual.

The ZUP series are wide range output switching power supplies with laboratory performance. The ZUP series is power factor corrected and operates from worldwide AC voltage range continuously. Output voltage and current are continuously displayed and LED indicators show the complete operating status of the power supply. The front panel controls allow the user to set the output parameters, the protection levels (over-voltage / under-voltage)and arm the foldback protection to disable the output if the unit switches from Constant-voltage mode to Constant-current mode.

The ZUP can be configured into a programmable power system of up to 31 DC outputs using the built-in RS232 or RS485 communication port in the power supply. In a GPIB system the GP485 controller can control up to 31 ZUP units in a single GPIB address.

Output connections are made to rear panel bus-bars for models up to 60V and connector for the 80V and 120V models. Either the positive or negative terminal may be grounded or the output may be floated. The maximum potential (including the output voltage) that either output terminal is from ground must not exceed the rated output voltage. Local or remote sense may be used. In remote sense, the maximum voltage drop on each wire is 0.5V for models up to 60V and 2V for the 80V and 120V models.

Analog inputs are provided at the rear panel for analog voltage programming of output voltage and current, and On/Off control. Inputs are provided for resistive programming of the output voltage and current.

Zup units of the same output voltage and current rating can be paralleled in master-slave configuration with automatic current sharing for power-up purposes.

The following parameters can be programmed via the serial communication port:

1. Output voltage setting

2. Output current setting

3. Output On/Off

NOTE

CAUTION

This chapter contains instructions for initial inspection, preparation for use and repackaging for shipment. Connection to PC, linking ZUP units and setting the address are described in chapter 5.

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 notify the Nemic-Lambda sales or service facility nearest you.

The mechanical inspection should confirm that there is no exterior damage to the power supply such as broken knobs or connectors and that the front panel and meter face are not scratched or cracked.

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.

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, theAC voltage supplied to the power supply does not fall below “low limit” specifications.

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

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 power supply. Refer to the outline drawing in this chapter for mounting details.

Connection of this power supply to an AC power source should

be made by

an electrician or other qualified personnel.

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.

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 inlet of 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.

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 CONNECTING THE LOAD

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 voltage drop per lead to 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.

3.7.3 Single load connection, Local Sensing

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

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.

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.

3.7.4 Single load connection, Remote Sensing

3.7.5 Multiple load connections, radial distribution method

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.

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 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.

3.8.1 General

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 or shielded wires. Each load should be separately connected to the remote distribution terminals. If Remote Sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load.

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

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 assignment is shown in Fig. 3-5 below.

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

4.4 LOCAL OPERATION

4.4.1 Introduction

4.4.2 Constant Voltage Operation

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 port usage, 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 change the operating mode to Local.

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

2. While the power supply is operating at constant voltage, the CV LED on 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.

3. For coarse output current adjustment, press V/Aconsecutively, until theA 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.

4.4.3 Constant Current Operation

NOTE

4. For fine adjustment of output voltage, press V/Aconsecutively until the V LED illuminates and the VOLTS display shows SL_V. TheAMPS display will show the output voltage setting value. Rotate theADJUST knob to set the output voltage. At this mode the adjustment resolution is maximal. Approx 3sec. after the adjustment, the display returns to show the actual voltage and current.

4. For fine adjustment of output current, press V/Aconsecutively until the A LED illuminates and

the VOLTS display shows SL_A. TheAMPS display will show the output current setting value. Rotate theADJUST knob to set the output current. At this mode the adjustment resolution is maximal. Approx 3sec. after the adjustment, the display returns to show the actual voltage and current.

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 supply is operating at constant current, the CC LED on the front panel illuminates.

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.

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.

4.4.4 Automatic Crossover

4.4.5 Over Voltage Protection (OVP)

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.

1.The OVP circuit monitors the voltage at the power supply sensing points thus guaranteeing the protection level at the load. Upon detection of Over Voltage condition, the power supply will shut down. To resume operation, the power switch should be turned off for approx. 30sec. Prior to turn-on, check carefully that the sense wires are connected correctly and secured.

2. OVP setting values are limited at the minimum and maximum levels.At minimum level, the OVP level is limited by the Output Voltage setting, therefore the OVPlevel cannot be adjusted below the Output Voltage.At maximum level, the OVP level is limited to the values shown in Table 4-1.

Table 4-1: Maximum OVP setting levels.

4.4.6 Under Voltage Protection (UVP)

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 theADJUST knob to set the over voltage protection level.Approx. 3sec after the adjustment, the display returns to show the actual voltage and current.

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

At this time the display will show the OVP set value for 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.

1.The UVP prevents adjustment of the output voltage below a certain limit. The combination of UVP and OVP functions allows the user to create a protection window for sensitive loads circuitry.

2. For under voltage protection adjustment, press OVP/UVP consecutively until the UVPLED illuminates and the VOLTS display shows UUP. The AMPS display will show the under voltage protection setting value. Rotate theADJUST knob to set the under voltage protection level.

3. In order to see the set value of the UVP, press OVP/UVP pushbutton, so that the UVP LED illuminates.At this time the display will show the UVP set value for approx. 3sec.

4. The maximum under voltage level is approx. 95% of the output voltage set value. An attempt to

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

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

4.4.8 Output ON/OFF Control

4.4.7 Foldback Protection

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. Foldback protection will shut down the power supply output if the load current exceeds the current limit setting level. This protection is useful when the load circuitry is sensitive to over current condition.

2. To arm the Foldback protection, the FOLD pushbutton should be pressed so the FOLD LED

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

3. Activation of the Foldback protection disables the power supply’s output, turns on the ALM (alarm)

LED and flashes the FOLD LED.

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

1. Short press on FOLD pushbutton enables the output and re-arms the protection circuit. If the load

is smaller than the current limit level, the power supply will restore normal operation. If the load is greater than the current limit level, the output will be disabled again and Foldback indicators will be on.

2. Long press (approx. 3sec) on FOLD pushbutton will disable the Foldback protection circuit and

enable the output. The power supply will restore operation to Constant Voltage or Constant Current mode depending on the load characteristics and power supply setting.

1. Rear panel ON/OFF Control

2. Front 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 shown in Fig. 4-4.

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

4.4.9 Last Setting Memory

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 while AS 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.

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 of the power supply.

4.4.10 Output Voltage & Current programming by external resistor

In this mode, the power supply restores it’s last operation setting and sets the OUT 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.

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

supply 1mAcurrent through external programming resistors. The voltage across the programming resistors is used as a programming voltage for the power supply. Resistance of 0~4kohm programs

the output from 0 to full scale (full scale is 105% of the rated voltage or current). Avariable resistor can control the output over it’s entire range, or a combination of variable resistor and series/parallel resistors can control the output over a restricted portion of it’s range.Alternatively, a switch can be used to select fixed values of programming resistance to obtain a set of discrete voltages or currents. Care must be taken to avoid open circuit at the programming resistors, as it will cause over-voltage at the output. In this case, no damage to the power supply will be caused

however,it is recommended to set OVP limit to a level which is 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, with temperature coefficient of less than 25ppm and power rating of 1/4W or more.

3. Where external resistor programming is used, front panel control and computer control (via serial communication) of the output voltage and current are disabled.

4. OUTPUT VOLTAGE PROGRAMMING BY EXTERNALRESISTOR

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 0 and 4Kohm.

NOTE

Resistive programming is possible for local and remote sensing.

CAUTION

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 (via the serial communication) are disabled. Note: Full scale is 105% of the rated output voltage.

Fig. 4-8 shows the set-up for external voltage programming of the output current. A voltage source variable from 0 to 4V, programs the output current 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. Note: Full scale is 105% of the rated output current.

The Com pin at the external control connector is connected to the -Sense potential. NEVER

connect the Com pin (pin10) to any potential, as it may damage the power supply.

Avoid connection of resistors greater than 4kohm or voltage greater than 4V for external resistor

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

4.While operating in CV mode, the master unit regulates the output voltage and the slave units operate as controlled current source, following the master output current. It is recommended to design the power system so that each unit will supply up to 95% of it’s current rating, because of an imbalance which may be caused by cabling and connections voltage drop.

The master unit OVP should be adjusted to the desired OVP level.The OVP of the slave units should be adjusted higher than the Master OVP. When the master unit shuts down, it programs the slave units to zero output voltage. If a slave unit shuts down (when it’s OVP is set lower than the master output voltage), only that unit will shut down and remaining slave units will supply all the load current.

At auto-parallel mode, power supplies can be connected in local or remote sensing. Refer Fig. 4-9, 4-10 & 4-11 for typical connections of paralleled power supplies. The figure below shows connection of two units, however the same connection method applies for up to 5 units.

NOTE

With local sensing it is important to minimize the wire length and resistance. Also the wires

resistance should be as close as possible to achieve current balance between power supplies.

1.Up to five units of the same rating can be connected in an auto-parallel combination to provide up to five times the output current capability. One of the power supplies operates as a master and the remaining units as slaves. The slave units are analog programmed by the master unit. At remote operation, only the master unit can be programmed by the computer while the slave units may be connected to the computer for actual voltage and current readback only.

2. 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.

3. Setting the voltage and current: The output voltage of the slave units should be programmed higher than the output and the master to avoid interference with the master CV control. Output voltage of the master should be programmed to the desired voltage, and the current limit to the desired load current divided by the number of

parallel units. During operation, the master unit operates at CV mode and the slave units at CC mode.

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.

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.

4.4.14 Series Operation

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

2. Series connection for increased output 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 4-13 for this operating mode.

2.2 Remote programming at series operation for increased output voltage:

1. Programming by external voltage; The analog programming circuits of the ZUP power supply are referenced to the - Sense potential. Therefore, the circuits used to control each unit must be separated and floated from each other.

2. Programming by external resistor: Programming by external resistor is possible. Refer to Fig. 4-5 and Fig. 4-6 for details.

3. Programming via the communication port (RS232/RS485): The communication port is isolated from the output voltage, therefore power supplies connected in series, can be chained using the Remote-in and Remote-out connectors.

4.4.15 Output Good Signal

Typical applications of 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 10mAand the maximum voltage is 40VDC.

1. In multiple power supply systems, it is possible to disable all the units when a critical unit fails. Refer to Fig 4-15 for typical connection diagram.

2. Hierarchical structure in multiple supply systems:It is possible to define a hierarchy in multiple supply systems by enabling any N+1 unit by the Output Good signal of the N unit. In this structure, failure of the N unit will cause all the following units to be disabled. Refer to Fig 4-16 for typical connections diagram.

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.

Fig. 4-15: Disabling multiple supply systems.

- V

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.

This chapter describes the operation of the ZUP series via the serial communication port. details of the initial set-up, operation via RS232 or RS485, the command set and the communication protocol are described in this chapter.

The ZUP addresses can be set to any address between 01 and 31. Follow the procedure described below to set the address.

1. Momentarily press theADDR pushbutton on the front panel so the ADDR LED illuminates and the VOLTS display shows ‘Addr’.

2. Rotate the front panel knob. While rotating the knob the AMPS display will show the selected address. When the rotation is stopped, the address shown will be the selected address. The display will return to show the actual voltage and current approx. 3 sec. from termination of rotating knob.

3. While the unit is in operation, depressing theADDR pushbutton will cause the display to show the

selected address.

To select between RS232 or RS485 serial communication the following steps should be taken.

1. Press and hold REM pushbutton.(holding REM depressed for more than 1sec does not change the local/remote status).

2. Press and hold REM pushbutton.After approx. 3sec. the display will continuously cycle between

‘rs232’ and ‘rs485’ approx. every 3sec.

3. To select RS232, release the REM pushbutton while ‘rs232 is displayed. To select RS485, release

the REM pushbutton while ‘rs485 is displayed.

4.Approx. 3sec after releasing the REM, the display returns to show the actual voltage and current.

Six optional rates are possible:300, 600, 1200, 2400, 4800, 9600. To select the desired rate, the following steps should be taken. The power supply should be at Local operation mode during the following procedure:

1. Press and hold ADDR pushbutton. After approx. 3 sec. the display will continuously cycle between

the six optional rates approx. every 2 seconds.

2. To select the desired rate, release ADDR while that rate is displayed.

3.After releasing ADDR the display will return to show the actual voltage and current.

To enable the operation via RS232 or RS485, the power supply should be at Remote mode. At this mode, all the front panel functions are disabled except Local/Remote pushbutton.

Transition from Local to Remote control:

1. Via the front panel: Momentarily press REM pushbutton

so the REM LED illuminates. To return from

Remote to Local control, momentarily press REM pushbutton so the REM LED extinguishes.

2. Via the serial communication port (RS232/RS485): By sending a :RMTn; command to the power supply. Refer to par.5.5.2.

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.

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

5.6 COMMUNICATION PROTOCOL

5.6.1 General Information

5.6.2 Accessing a ZUP Unit

5.6.3 End of Message

The average command processing time of the ZUP Series is 15mSec. It is not recommended to send strings of commands to the ZUP power supply without considering the processing time. For query commands ( ? , ! ) , wait until the ZUP reply message has been completed , before sending a new command.

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 be sent 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.

The messages generated by the ZUP are terminated by an end of message: < CR > carriage return character < LF > line feed character

When sending a message to the ZUP, there is no need for the end of message characters.

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.

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.
