■ Description

LCM-25KNseriesisa25WAC/DCconstantcurrentmodeoutputLEDdriverfeaturing

themultiplelevelsselectablebydipswitchandtheKNXinterfacetoavoidusingthe

complicatedKNX-DALIgateway.LCM-25KNoperatesfrom180～277VACandoffers

differentcurrentlevelsrangingbetween350mAand1050mA.Thankstotheefficiency

upto85%,withthefanlessdesign,theentireseriesisabletooperatefor-30℃~+85℃

casetemperatureunderfreeairconvection.Inaddition,LCM-25KNisequippedwith

pushdimmingandsynchronizationsoastoprovidetheoptimaldesignflexibilityfor

Built-inKNXinterface
