Prior to shipment this powersupply was inspected and foundfree of mechanical or electricaldefects. Uponunpacking ofthepower supply,inspectforany damage whichmayhave occurredintransit.Keep all packing materials until inspection has been completed.If any damage is detected,file a claim with thecarrierimmediatelyand notifytheNemic-Lambda salesor servicefacilitynearest you.

Themechanical inspectionshouldconfirm thatthereis noexteriordamage tothepower supplysuchas brokenknobsorconnectors andthatthefrontpanel andmeterfacearenot scratchedorcracked.

In order tobe operational the power supplymust be connected to an appropriate AC source.The line voltagemustbewithinthe 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 heavyload,theAC voltagesuppliedtothepower supplydoesnotfallbelow “lowlimit”specifications.

This power supply is fan cooled. Upon installation ensure sufficient space for air intake (front panel) andexhaust(rearpanel).Thepowersupplyshouldbeusedinanarea wherethe ambient temperature

doesnotexceed+50 C

ZUP models can be mountedin a standard19” rack(3U height).The 200W and400W models occupy 1/6 rack length. The 800Wmodel occupies1/3 racklength. Thepower suppliesshould befixed byM4 screwsreplacing therubberfeetonthe bottomofthe powersupply.Thescrewsmust notprotrudemore than6mmintothe powersupply.Refertothe outlinedrawinginthischapter formounting 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 athree conductorpower cable. The third conductor is the ground conductor.When the cable is plugged-in to anappropriate 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. Tomeet radiated EMIspecification, the EMI suppressor clampshould be attachedto the ACcable as closeas possibleto theACinlet ofthe powersupply.

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.

3.7 CONNECTING THE LOAD

3.7.1 Selecting wire size

Twofactorsmustbeconsidered inselectingwiresize.

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, whicheverisgreater.

2.Wire sizeshouldbe selected toenablevoltage dropperleadto belessthan 0.5Vattherated current. It is recommended to minimize voltage drop on the wires to prevent excessive output power consumptionfrom thepower supply. Please refer to Tables 3-1 and 3-2 for maximum wire length to limit voltage drop by American and Europeanmeasurements respectively.

CAUTION

At local sensing, short between +LS or +S to -V or -S or -LS will cause damage to the

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 usedin cases where, inConstant Voltagemode the loadregulation isimportant at the load terminals. Use twisted orshielded wires tominimize noise pick-up.If shielded wiresare used, the shield should beconnected to the groundat onepoint, eitherthe power supply chassisor the load ground. The optimalpoint forthe shield groundshould be determinedby experimentation. AtRemote Sensing,the maximumvoltage dropallowedat theload wiresis0.5Vperwire.

In cases of multiple loads connected to one supply, each load should be connected to the power supply’s output terminals using separatepairs of wires. It is recommended thateach pair of wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation. The sense wiresshouldbe connectedtothepower supply outputterminalsorto the loadwiththe most criticalload regulationrequirement.

3.8.1 General

Ifremotely located output distribution terminals areused, the power supplyoutput terminals shouldbe connected to the distribution terminals by a pair of twisted or shielded wires. Each load should be separately connected tothe remote distribution terminals. If Remote Sensing isrequired, the sensing wiresshouldbeconnected tothedistribution terminalsor atthemostcriticalload.

Either the positive or negativeoutput terminals can be grounded. Toavoid noise problems caused by common-mode current flowing from the load to ground, it is recommended to ground the output terminalascloseas possibletothepowersupply 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 rearpanelofthe unit,(Fig.4-2,item4).The pinassignmentisshownin Fig.3-5 below.

4.OUTPUTVOLTAGEPROGRAMMINGBYEXTERNAL RESISTOR

Fig 4-5 shows a typical set-up for programming the output voltage. A variable programming resistor, 0~4Kohm produces aproportional output voltagefrom zero tofull scale. Inorder to setthe low limit, a seriesresistor canbeconnected to theprogrammingresistor.For example; a1kohmseries resistorwill 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 resistorsmustbebetween 0and4Kohm.

CAUTION

Fig. 4-7 shows the set-up for external voltage programming of the output voltage. A voltage source variablefrom0 to 4V,programs the output voltage proportionally from zero tofull 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 programmingthe frontpanel andthecomputer control(via theserialcommunication) aredisabled. Note:Full scaleis 105%oftheratedoutput 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 outputcurrent proportionally fromzero to fullscale. The staticload current on the programming source is less than 2uA. The source resistance should be less than 10Kohmto avoiddegradation ofoffsetanddriftspecifications. Note:Full scaleis 105%oftheratedoutput 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.

4.4.15 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 supplyoperates normally,the Output Good islow (0~0.8V). When the powersupply 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 currentis10mAand themaximumvoltageis40VDC.

1.In multiplepower supplysystems,it ispossible todisablealltheunits whenacriticalunitfails. Refer toFig4-15for typicalconnectiondiagram.

2.Hierarchicalstructurein multiplesupplysystems:It ispossible todefineahierarchyinmultiplesupply systemsby enablinganyN+1unitbytheOutput Goodsignalof theN unit.Inthisstructure,failure of theN unitwill causeallthefollowingunits tobedisabled.Referto Fig4-16fortypicalconnections 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.

1.Operational StatusRegister: The operational status register recordssignals that are partof the powersupply’s normal operation. In addition to the normal operation data, the register holds an alarm bit which indicates that one of the alarm(fault) registerbitsis set.Theregister isautomaticallyupdated andreadingit does notchange it’s content.Clearing the register is done by DCL command. See table 5-5for Operational Status Register content.

Note: *1In caseof ACfail,thealarmstatus register‘ACfail’bitwill beset butwillnot setthe alarmbit.

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 timeof the ZUP Series is15mSec. Itis not recommended to send stringsofcommands to theZUPpowersupplywithout consideringtheprocessing time. Forquery commands ( ? , ! ), wait until theZUP reply message hasbeen completed , beforesending a new command.

The default condition of the ZUP series isListen 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’saddress becomesactive and can communicate with the hostcontroller.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’sstate to Listen mode and theaddressed unitbecomes active.

Eachmessage sentby theZUPisterminatedby anendofmessage. <CR> carriage returncharacter <LF> line feedcharacter

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.
