NFC15 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• 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.

Notes

1 Nominal input voltage is 48VDC.

2 Maximum figure, at full load.

3 Measured from low line to high line at full load.

4 Measured from full load to no load.

5 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, 56µF, 100V.

6 As a factory added option, the NFC15-48S15 can be operated down to

–40°C. The suffix ‘–4’ should be added to the model number when

ordering, e.g. NFC15-48S15-4.

7 Maximum case temperature must not be exceeded. Derating curve may

be extended or restricted depending on cooling.

8 Long term continuous operation into a short circuit will compromise the

reliability of the unit.
