1. OUTLINE
2. FEATURES
The PWR Series isa fullyremote-controllable, multiple-output
DC constant-voltage/currentpowersupply.The series incor-
porates a LISTENER function,whichallowsremotecontrolof
all thefunctionsofthePW Series, anda TALKER function,
which allowsread-backofallpresetconditionsand output cur-
rent/voltage values.
Equipped witha computer-controlledmeasurementsystemand
numerous programmablefunctions,thePWR Series isa ver-
satile machinewhichisusefulfora widerangeofapplications.

• Expansion to System-Level PowerSupplyvia
GP-IB Control
The PWRcanbecombinedwiththe GP-IB adapter (GP-620,
sold separately)toenableusewithautomationmeasurement
systems, andisequippedwitha LISTENER/TALKER function
thatenablescontrolofalltheunit'sfunctionsandenables read-
back ofall output voltage/current values. UsingIDrecognition,
allows constructionofhigh-security systems capableofcon-
trolling uptofourunits.
• Expansion toProgrammablePowerSupplyvia

1. MASTEROperation
During MASTER Operation,the MASTER unitoperatesin
TALK ONLY mode,andthe SLAVE unitsoperatein LISTEN
ONLY mode.
Therefore, thereshouldbenointermixingofmachinetypes,
and machinesofallthesamemodelshouldbe used.
©Interconnectingmachineswiththeconnecting cords.
Turn thepowerswitchesofallthemachinesto "OFF" and,us-
ingtheconnectingcordsprovided,connectthemachinesas
shown below.BesuretoconnectonlyINterminalstoOUTter-
minals, andneverconnectINtoIN.
(DDesignatingthe MASTER Unit.
1) Turnthe POWER switchofPWR# 1 to"ON"whiledepress-
ingtheA key.WhentheV.Adisplayappearsasshowninthe

(3) Designatingthe SLAVE units.
1) Asintheprocedurefordesignatingthe MASTER unit, when
designatinga SLAVE unit, turn the POWER switchto"ON"
whiledepressingtheA key,andsetthe ADDRESS NO.us-
ingtherotaryencoder.Whensetting SLAVE unit address-
es, usethenumbers from 1 to26,butdonotuse"0".
2) WhentheA keyis depressed, the unit willreturntothestate
describedin (T), whichoccursbeforethe POWER isturned

3) Setthe ADDRESS NO.'softheother SLAVE unitsinthe
same way.
TheADDRESS NO.ofeach slave unit canbeselected
from amongthenumbers1 through 26.However,to
avoidconfusion,assigna unique ADDRESS NO.toeach
ofthe slave units.
