12V 30A Switching Supply for Industrial Projects

This regulated switching power supply converts AC 110V or 220V input to a steady 12V DC output rated at 30A and 360W. It suits CCTV installations, radio equipment, computer projects, LED strip lighting and 3D printer builds. The aluminium enclosure measures 215 by 114 by 50mm and weighs 660g. Indoor use only; the unit is not waterproof.

Check Input Voltage Switch Before Powering On

The supply features a physical selector for 115V or 230V AC input; you must set it to match your mains voltage before connecting power. Verify that your load does not exceed the 29.2A maximum output current. Ensure the installation location provides ventilation for the aluminium case and that wiring to the L, N, COM, V and +V/ADJ terminals follows the labelled polarity.

Adjustable Output and Protection Features

A built-in potentiometer allows roughly 10% output voltage adjustment via the +V/ADJ terminal for fine-tuning connected devices. Protection circuits cover short-circuit, overload and over-voltage conditions at 115% to 135% of nominal, with automatic reset or fuse intervention. The unit carries FCC and CE safety compliance for regulated environments.

Questions about this item

Does the supply ship with a power cord or only the bare unit?

The unit arrives as the bare supply; an AC mains lead for the L and N terminals must be sourced separately.

Should I pick the 115 V or 230 V input setting for UK mains?

UK mains run at 230 V, so slide the selector switch to the 230 V position before applying power.

The label says 30 A but the spec sheet lists 29.2 A — which figure will I actually get?

The continuous rating is 29.2 A at 12 V DC; the 30 A figure is the nominal design target.
