NFC15 SERIES
Single and dual output
* * * * * * * * 4:1 input voltage range Low profile 0.46 inch 10.2 Watts/cubic inch 80% efficiency UL, CSA and VDE safety approvals Inhibit/sync function Overvoltage protection Fixed frequency operation
The NFC15 series of DC/DC converters are economical 15 Watt, hybrid DC/DC converters that accept input voltages ranging from 20VDC to 72VDC. A constant efficiency of 80% is maintained over the entire input voltage range. The isolated floating output can be referenced as either positive or negative, or stacked in series for higher output voltages. All models include current limited outputs, overvoltage protection and remote on/off. Packaged in a low profile 2.0 x 1.6 x 0.46 inch case, the NFC15 is ideal for space critical applications in telecommunications, data communications and distributed power networks.

Nominal input voltage is 48VDC. Maximum figure, at full load. Measured from low line to high line at full load. Measured from full load to no load. An external filter capacitor, connected across the inputs, is required for normal operation. Capacitor should be capable of handling 600mA ripple current. Suitable capacitor: Nippon Chemi-Con SXE series, 56F, 100V. As a factory added option, the NFC15-48S15 can be operated down to -40C. The suffix `-4' should be added to the model number when ordering, e.g. NFC15-48S15-4. Maximum case temperature must not be exceeded. Derating curve may be extended or restricted depending on cooling. Long term continuous operation into a short circuit will compromise the reliability of the unit.
