NFC10 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• 10 Watts output power

• 2:1 input voltage range

• UL, CSA and VDE safety approvals (48V input units)

• Overvoltage protection

• Extended operating temperature range

• Fixed switching frequency

The NFC10 offers 10 Watts of output power from a 2 x 1 x 0.375 inch package

without derating to 71°C. A range of 15 models with 2:1 wide input voltages of

9–18, 18–36 and 36–72VDC and single and dual outputs are offered. Features of

the NFC10 series include fixed frequency operation, high MTBF, overvoltage

protection and tight load regulation. All of the models have been designed to

meet EN60950 (Vin <60VDC) safety requirements. Typical applications are

telecommunications, industrial automation and distributed power.
