NFC20 SERIES
Single and dual output
* * * * * * * * 20 Watts output power Power density 13.6W/in3 2:1 input voltage range Remote ON/OFF control UL, CSA and VDE safety approvals Overvoltage protection Extended operating temperature range Fixed switching frequency
[ 2 YEAR WARRANTY ]
The NFC20 series of DC/DC converters offers 20 Watts of output power from the industry standard 2 x 1.6 x 0.46 inch case without a heatsink. Advantages of the NFC20 include increased power density, fixed switching frequency, tight line and load regulation, reduced board area requirements and many standard features. Among these features are remote on/off control, overvoltage protection, synchronization function and an extended operating temperature range option. Input voltage ranges of 18-36VDC and 36-72VDC mean that the NFC20 is ideally suited to process control, industrial automation, distributed power and telecommunications applications.

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, 56F/100V for the NFC20-48xxx and the Nippon Chemi-Con LXF series, 560F/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.
