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.
