NFC20 SERIES
Single and dual output
• 20 Watts output power
• Power density 13.6W/in
• 2:1 input voltage range
• Remote ON/OFF control
• UL, CSA and VDE safety approvals
• Overvoltage protection
• Extended operating temperature range
• Fixed switching frequency
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.
