Features

The power switch is equipped with a series of short circuit/overload/overvoltage/overtemperature protection functions.

The power consumption of a switching power supply is <0.75W when it is idle.

The series as a whole accepts 115VAC or 230VAC input (depending on switch selection) and provides output voltage lines of 12V, 15V, 24V, 36V, and 48V.

This switching power supply can tolerate a 300VAC surge input for a duration of 5 seconds.

Our product can provide a cost-effective power supply for various industrial applications.
