• 3 WATTS REGULATED OUTPUT POWER • 2:1 WIDE INPUT VOLTAGE RANGE • INTERNATIONAL SAFETY STANDARD APPROVAL • OVER CURRENT PROTECTION • HIGH EFFICIENCY UP TO 80% • STANDARD 24 PIN DIP PACKAGE & SMD TYPE PACKAGE
UL E193009 TUV R50008270 CB JPTUV-003680 CE MARK
The PFKC03 series offer 3 watts of output power from a package in an IC compatible 24 pin DIP configuration without derating to 71ºC ambient temperature and pin to pin compatible to PFKC05,FKC03,FKC05 series.
PFKC03 series have 2:1 wide input voltage of 4.
5-6, 9-18, 18-36 and 36-75VDC.
PFKC03 features 1600VDC of isolation and, short-circuit protection and suffix “H” can get 3000VDC isolation.
All models are particularly suited to telecommunications, industrial, mobile telecom and test equipment applications.
