The FEC15 series offer 15 watts of output power from a 2 x 1 x 0.4 inch package. The
FEC15 series with 2:1 wide input voltage of 9-18, 18-36 and 36-75VDC. The FEC15
features 1600VDC of isolation, short-circuit and over-voltage protection, as well as six
sided shielding. A safety approval to EN60950-1 and UL60950-1. All models are
particularly suited to telecommunications, industrial, mobile telecom and test equipment
applications.
