•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
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.
All specifications are typical at nominal input, full load and 25ºC otherwise noted
