Name: DIN Rail Power Adapter 75W
Brand: ORing
SKU: SDR-75-48

Feeds 48 V DC loads in tight panels.

A switching power supply that converts mains voltage to 48 V DC. It works across the 88 ~ 264 V AC range and starts up in environments down to -30 °C. The 32 mm wide case takes little space on the DIN rail.

Key features

112.5W

Peak power capacity

Covers the start-up load for 3 seconds.

2.34A

Peak current capacity

Covers the extra current drawn at start-up.

90%

Conversion efficiency

Transfers most of the input power to the output.

32mm

Body width

Takes little space on the DIN rail.

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.
