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.
