1. IntroductionandFeatures
ThankyouforselectingtheExtechDCP42SwitchingModePowerSupply.Thisnewlyre‐designed
laboratorygradepowersupplydiffersfromaconventionalpowersupplyinthatitcancalculate
andchangethevoltageandcurrentlimitpointsaccordingtotheavailablemaximumpower.
Thereforethemaximumlimitsofthevoltageandcurrentarechangeableaccordingtotherated
power.Aconventionalpowersupplyhasonlyasetmaximumvoltageandcurrentsuchthatallof
theoperatingV&Amustfallwithintheselimits.TheDCP42offerscostsavingandspacesaving
advantagesasoneconstant‐powerpowersupplycandotheworkofseveralconventionalpower
supplies.

TheDCP42ishighlyefficient,incorporatesupgradedSMPScircuitrywithsmallformfactor,benefits
fromanautomaticcross‐overforCCandCV,hasthree(3)Voltage/Currentpresets,andcanbe
remotecontrolled.TheDCP42isperfectforsolvingavarietyofloadingconditionsandapplications.
Featuresincludethefollowing:

Dualaction(Course/Fine)tuningprovidessmooth,accurate,andquicksettingof
Voltage/Current
Setting,changing,andverifyingthecurrentlimitlevelisconvenientandcanbe
performedwithoutoutputpolespiking
TheRemoteControlfeaturepermitsoutputON/OFFandVoltage/Currentadjustments
withouttheneedtotouchthefrontpanelofthepowersupply
TheUSBportoffersPCconnectivityforprogrammingandrunningramp/soakcycleswith
20programmablesetsofVoltage/Currentandvaryingtestdurations(upto999cycles)
TheDCrampandwaveformgeneratorcaneitherbepanelsetorsetbythesupplied
softwarewhichpreviewsthefinalwaveform.
ApplicationsandindustrieswheretheDCP42canbeemployedincludelaboratory,
telecommunications,productiontesting,fieldtesting,DCnetworkpowering,andmore
Three(3)userprogrammableVoltage/Currentsettingsofferquickrecalloffrequently
usedtestsettings.

Thisdeviceisshippedfullytestedandcalibratedand,withproperuse,willprovideyearsofreliable

11.Troubleshooting
OUP:OverVoltageProtection
Thisunithasabuilt‐intrackingovervoltageprotectionfeature.Intheeventofoutputvoltage
becominggreaterthanthesetvalue(seespecifiedrangefromspecificationstable),protection
willbetriggeredandtheoutputpowerwillbecutoffandOUPwarningappearsasbelow.

Toresetthewarning,switchofftheunitandremoveallloading.
Switchtheunitbackonagainanditshouldresumenormaloperation.
Ifthisproblempersists,pleasecontactthecustomercaredepartmentorthepointofpurchase.

OTP:OverTemperatureProtection
Thereisathermosensorinsidetheunittomonitorandpreventtheunitfromundulyheating
internally.WhenanOTPerroroccurs,thereisnooutputandthefollowingwarningwillappear
ontheLEDdisplay.

Whenthiswarningappears,switchofftheunitandremoveallloading.
Checktheloadandoutputsetting.Allowtheunittocoolforatleast30minutes.
Checktoseeifanyventilationholesareblocked,alsocheckthatthereissufficientclearance
aroundthepowersupply.
Listencarefullyfortheshortwindsoundemanatingfromthecoolingfanwhentheunitis
switchedONagain.Ifthewindsoundisnotdetected,thefanmaybefaulty;donotusethe
powersupplyinthiscase,contactthecustomercaredepartmentortheagentfromthepointof
purchase.

OCP:OverCurrentProtection
NormallytheoverloadprotectionissustainedbytheCCconstantcurrentmode.WhentheCC
modefailsandgoesundetected,seriousdamagetothetestpieceorloadmayoccur.TheOCPis
usedtominimizetheextentofdamagetotheloadsintheeventofpowersupplyfailure.
Switchoffthepowersupplyassoonasthiswarningisseen(asshownbelow).

Toresetthiswarning,removeallloadingandpresstheOUTPUTON/OFFbutton.
Switchtheunitbackonagainanddoublecheckwithcaution.
Ifthisproblempersists,pleasecontactthecustomercaredepartmentorconsultwiththeagent
atthepointofpurchase.
