CE-IJ03 -***SK-0.5
1 Overview
Thisdevice isa1-elementac currentisolation transducer.Using
theprincipleofelectromagneticisolation,cansamplingtheRMS
ofthesingle-phase ACcurrent,and isolatetheoutputofavariety
ofstandardsignals.Betweentheinputand outputtoachieve
electricalisolation,theoutputsignalandtheinputsignalhas a
completelinearrelationship.TheproductsarewidelyusedinAC
currentsignalreal-timemonitoring,electricity,railways,industrial
monitoringandotherfields.
Features:
ØHighaccuracy, lowdrift;
ØPressureresistance oftheproductsamongtheinput,output
and powersupplyreach2.5KV;
ØTheuse ofstandardrail mounting and screwmounting,easy
toinstall;
