400 WATT POWER FACTOR CORRECTED SUPPLIES

DESCRIPTION

The PFC400 series of AC/DC switching power supplies are capable of

delivering 400 watts of continuous power and incorporate active power

factor correction. Three outputs in each unit are equipped with current

sharing and oring diode for redundant applications. Other features

include remote sense, Power Fail Detect signal and isolated outputs.

The units are constructed on a printed circuit board with a U-bracket

for mechanical support and heat sinking. The series is designed for use

in medium-power data networking, telecom, industrial, test and office

equipment.

at 112-132﹪ of its nominal

output voltage

Overcurrent protection：

All outputs protected to short

circuit conditions

Temperature coefficient：
