FIXED SWITCHING FREQUENCY
The FEC40 series offer 40 watts of output power from a 2 x 2 x 0.4 inch package. The FEC40 series
with 2:1 wide input voltage of 9-18VDC,18-36VDC and 36-75VDC and features 1600VDC of
isolation, short-circuit and over-voltage protection, as well as six sided shielding. All models are
particularly suited to telecommunications, industrial, mobile telecom and test equipment applications.
