LRS-450 Switching Power Supply 450W 12V 15V 24V 36V 48V Power Supply IP20

The LRS-450W series adopt an outward FAN cooling dissipation design. This design greatly improves the stability of the product.

This product complies with complete international safety regulations such as CE/BIS and others.

At WEHO, we are adamant about maintaining quality power supplies with a maximum efficiency of 92%.

In addition, the LRS-450W&500W implements 3 seconds constant current limit for overload protection and enhances greater flexibility when dealing with inductance and capacitance loads.

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.
