12V 20A Switching Power Supply

This switching power supply converts AC mains voltage into a regulated DC12V 20A output. It is intended for professional use with LED lighting, CCTV security cameras and surveillance systems. The unit accepts a wide input range of AC110-265V at 50/60Hz. Protections include overload, over-voltage and short-circuit safeguards.

DC12V 20A regulated output

The single specification that determines suitability is the DC12V 20A regulated output. Connected devices must operate at 12 volts and draw no more than 20 amps in total. The output voltage can be adjusted slightly via the +V/ADJ terminal. The supply delivers stable current without flicker to protect LED lifespan.

Screw-terminal wiring and free-convection cooling

Installation uses screw terminals labelled L and N for AC input, GND for DC negative and V for DC positive. No fan is fitted; cooling relies on free convection so adequate airflow around the 645g enclosure is required. The operating temperature range is 0~40°C and humidity tolerance is 0~95% non-condensing. Compatible LED strip types include 3528, 2835, 3014, 5050, 5630 and 5730. Not for buyers who need a higher voltage output or a unit rated for outdoor weather exposure.

Questions about this item

What does the 20 A output mean for my LED strips?

The unit delivers up to 20 A at 12 V, so you can power multiple 3528, 2835, 3014, 5050, 5630 or 5730 strips within that current limit.

How does the AC 110-265 V input range affect where I can use it?

It accepts any mains voltage from 110 V to 265 V at 50 or 60 Hz, making it suitable for worldwide use without a separate voltage selector.

What mounting or wiring does the supply need?

It uses screw terminals labelled L and N for AC input, GND and V for DC output, plus an ADJ trimmer for fine voltage adjustment; cooling is by free convection.
