Startup and operation
a) Connection and startup procedure
• Placethelaboratorypowersupplyonastable,evensurface.
• Theon/offswitch(8)shouldbeturnedto“OFF”.
• Connectthemainsplugoftheincludedmainscabletothemainssocket(14)onthebackofthedeviceandthepowerplug
toapoweroutletwith230V/AC,50Hzalternatingcurrent.
• Turnonthelaboratorypowersupplybypushingtheon/offswitch(8)to“ON”.
• BothLEDdisplays(1and2)lightupandshowthecurrentlysetcurrentandvoltagevalues.
• Dependingonthesettingofthecontroldial“CURRENT”(9)foroutputcurrentlimit,eithertheLEDdisplay“CV”(10)for
outputvoltageregulationortheLEDdisplay“CC”(11)foroutputcurrentregulationwilllightup.
• Thelaboratorypowersupplyisnowreadytosettheoutputvoltageandcurrentlimit.
b) Setting the output voltage
Inorderforthecorrectoutputvoltagetobeset,thelaboratorypowersupply’soutputmustbeoperatedinavoltage-controlled
state.
• Turnthecontroldial“CURRENT”(9)foroutputcurrentlimitfromtheleftpositionclockwiseuntiltheredLEDdisplay“CC”(11)for
outputcurrentregulationgoesoutandthegreenLEDdisplay“CV”(10)foroutputvoltageregulationlightsup.
• Checkthecontroldial“FINE”(4)forexactvoltageadjustment.Itshouldbeatthemiddleposition.
• Then,usethecontroldial“COARSE”(3)toroughlysetthedesiredoutputvoltage.Thecurrentlysetvoltagecanbeviewed
ontheLEDdisplay“V”(2).Turnthedialclockwisetoincrease,counter-clockwisetodecreasevoltage.
• Thenusethecontroldial“FINE”(4)toexactlysettheoutputvoltage.
Ifyouhavetoturnthecontroldial“FINE”(4)untilitstops,returnittothemiddlepositionandadjustthesetting
withthecontroldial“COARSE”(3)beforemakingnalexactadjustments.
c) Setting the current limit
Readthesection“d)Connectingunits”beforeundertakingadjustmentsforthecurrentlimit.Foranexactcurrent
limitsetting,aunitmustbeconnectedandturnedon,andthelaboratorypowersupplymustalsobeturnedon.
ThelimitedcurrentvaluecanbeviewedontheLEDdisplay“A”(1)onlyduringuse.
First,usethecontroldials“COARSE”(3)and“FINE”(4)tosetthepermissibleoperatingvoltageoftheunittobe
connected(seesection“b)Settingtheoutputvoltage”).
• Withthecontroldial“CURRENT”(9)foroutputcurrentlimit,approximatelysettherequiredamperage.
• Turnthedialclockwisetoincrease,counter-clockwisetodecreaseamperage.
Whenbothcontroldialsforvoltageadjustment(3and4)areallthewaytotheleft,thevoltagedisplayshows
“00.0”volts.
Ifyouthenturnthecontroldial“CURRENT”(9)foroutputcurrentlimitallthewaytotheleft,thelaboratorypower
supplyswitchestocurrent-controlledmodeandthevoltagedisplayshowsaminimumvalue.Thisisduetothe
electricalstructureofthelaboratorypowersupplyandisnotasignofmalfunction.
d) Connecting units
First,verifythatthetotaloutputofallunitstogetherdoesnotexceedthelaboratorypowersupply’smaximumcapacity.
• Turnoffallunitswhenconnectingthemtothelaboratorypowersupply.Otherwise,sparksmayoccur,andthesocketsand
plugsmaybedamaged.
• Turnoffthelaboratorypowersupply.
• Connecttheunit’splusterminal(+)tothelaboratorypowersupply’splussocket(5)andtheminusterminal(-)tothepower
supply’sminussocket(7).Usecablesofappropriatedimensionswith4mmbananaplugsorusestandardizedlabcables.
• Groundtheunitsusingthelaboratorypowersupply’sprovidedgroundconnection(6).
• Turnonthelaboratorypowersupplyandtheunit.
Oncevoltageisappliedtotheoutputsocketsandtheunithasbeenturnedon,thecurrentvaluesforthecurrentlimit
andvoltageareshownontheLEDdisplays(1and2).
Dependingonthelaboratorypowersupply’soperationmode(current-orvoltage-controlled),theLEDdisplay
“CC”(11)foroutputcurrentregulationor“CV”(10)foroutputvoltageregulationlightsup.
• Ifnecessary,youcanalsoreadjustthevaluesforthecurrentlimitoroutputvoltageforactivatedoutputsockets.
• Turnofftheunitandthelaboratorypowersupplybeforedisconnectingaunit.
Caution!
Thelaboratorypowersupplyhasaprotectivecircuitthatlimitsthecurrentintheevenofashortcircuit.Toprevent
thelaboratorypowersupplyfromoverheating,alwaysturnitoffimmediatelyanddisconnectallconnectedunits
intheeventofashortcircuit.Allowthelaboratorypowersupply tocooldownandmakesurethatitiswell
ventilated.Theairvents(12)mustbecleanandfreeofdust,donotcoverthehousingopenings.
Thelaboratorypowersupply‘smaximumcontinuousoperatingtimeis8hours.Afterthisperiod,turnoffthe
deviceandletitcooldowntoroomtemperature.
Maintenance and cleaning
a) General care
• Neveruseaggressiveorabrasivecleaningagents,rubbingalcoholorotherchemicalsolvents,asthosecandamagethe
housingorevenaffecttheoperationoftheproduct.
• Theproductdoesnotrequireanymaintenance,donotdisassembleit.
• Disconnecttheproductfromthehouseholdpoweroutletandanyconnecteddevicesbeforecleaning.
• Tocleantheproduct,adry,softandcleanclothissufcient.Donotapplytoomuchpressuretothehousingtoprevent
scratching.Youcaneasilyremovedustusingalong-haired,softandcleanbrush.
b) Changing the fuse
Caution!
First,turnoffthelaboratorypowersupplyanddisconnectallcables.Thenunplugthedevice.
• Useaslottedscrewdrivertoslightlypushinthefuseholder(13)onthebackandopenthebayonetconnectorbyturningit
counter-clockwiseaquarterturn.Aspringwillautomaticallypushoutthefuseholder.
• Replacethedefectivefusewithanewoneofthesametypeandsamenominalrating(see“Technicaldata”).
• Replacethefuseholder,pushitinslightlyandusethescrewdrivertofastenitinplace.Checktoseeifthelaboratorypower
supplyworksproperly.
Troubleshooting
The laboratory power supply does not function, the displays do not light up.
• Checkthepowerswitch.
• Checkwhetherthemainsplugiscorrectlyconnectedtothemainssocket(14)onthebackofthedevice.
• Checkthefunctionalityofthepowersupplyline(outlets,fuses,circuitbreakers,etc.).
• Checkwhetherthecorrectmainsvoltageispresent.
The connected units do not function.
• Checkthepolarityoftheconnectionsockets(5and7).
• Checkwhetheracurrentlimitisactivated.
• Reducethechargetothelaboratorypowersupplyfromtheconnectedunits.
• Checktheconnectedunits’technicaldata.
