The FKC08 series offer 8 watts of output power from a package in an IC compatible 24pin

DIP configuration. FKC08 series have 2:1 wide input voltage of 9-18, 18-36 and 36-75VDC.

The FKC08 features 1600VDC of isolation, short circuit protection and as well as five sided

shielding. All models are particularly suited to telecommunications, industrial, mobile

telecom and test equipment applications.
