NFC10 SERIES
Single and dual output
[ 2 YEAR WARRANTY ]
10 Watts output power
Power density 13.3W/in3
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.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
