[ 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.
