Key features

76.8W

Continuous output capacity

Runs without interruption at rated power.

48V DC

Fixed supply voltage

Adjusts the output between 48 ~ 53 V.

81%

Conversion efficiency

Transfers most of the input power to the output.

3KVAC

Input-output isolation

Separates the input side voltage from the output circuit.

123.1Khours

Mean time between failures

Based on the MIL-HDBK-217F calculation.

IN DAILY USE

Fanless coolingCools by free air convection and uses no fan.

Protected outputShuts down the output on overload, overvoltage, over temperature and short circuit.

Simple mountingClips directly onto the DIN rail.
