IntroductionandFeatures
ThankyouforselectingtheExtechDCP60(110V)orDCP60‐220(220V)SwitchingPowerSupply.
TheDCP60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DCP60isperfectforsolvingavarietyofloadingconditionsandapplications.

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
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)
ApplicationsandindustrieswheretheDCP60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
