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, 56F, 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.
