Nominal input voltages are 24VDC and 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 capacitor, connected across the input is required for normal
operation. The capacitor should be capable of withstanding 600mA of
ripple current. Recommended capacitors: Nippon Chemi-Con SXE series,
56µF/100V for the NFC20-48xxx and the Nippon Chemi-Con LXF series,
560µF/50V for the NFC20-24xxx.
Extended operating temperature range is available on the following
models: NFC20-24S05, -24S12, -24S15, -48S05, -48S12 and -48S15.
The suffix –4 must be added to the NFC20 model number,
e.g. NFC20-48S05-4.
Long term continuous operation into a short circuit will compromise the
reliability of the unit.
