Power Supply for 12V Equipment

This 250W switching power supply converts AC mains input to a regulated 12V DC output rated at 20.835A. It is intended for installers and technicians powering surveillance cameras, LED strips or similar 12V industrial equipment.

Input Voltage Selector and Efficiency

A manual 110V/220V selector switch lets the unit operate on supplies from 100V to 240V AC. The converter runs at 84% efficiency with an output voltage tolerance of ±1%, reducing heat and keeping connected devices within spec.

Wiring and Installation Notes

The supply uses screw-terminal connections for both AC input and DC output; no plug-and-play cables are included. Installers must verify the selector matches local mains voltage before applying power, as an incorrect setting will damage the unit.

Questions about this item

Does the internal fan or any other part of the 250 W unit need periodic replacement?

The supply has no user-serviceable parts; the fan and capacitors are sealed inside the chassis and are not designed for owner replacement.

What limits continuous full-load operation of the 20.385 A output?

Thermal protection will shut the unit down if internal temperature exceeds its safe threshold during sustained 250 W delivery.

How much heat and fan noise should I expect when the supply runs at 250 W all day?

At 84 % efficiency roughly 40 W becomes heat, so the built-in fan runs continuously and produces audible airflow in a quiet room.
