SKU CH-MP75-7B6T4

Converts AC 110-265 V to regulated DC 12 V at 20 A with overload, over-voltage and short-circuit protection for CCTV cameras and LED strips

  • TypeAT
  • Reliable power for LED strips and CCTV with regulated 12V 20A output
  • Wide AC110-265V input works worldwide without a separate adapter
  • Built-in overload, over-voltage and short-circuit protection keeps connected devices safe
  • Compact 645g convection-cooled design fits tight enclosures and runs silently
  • Certified to CCC, FCC and CE standards for professional installations

12 V 20 A switching supply

This regulated power supply converts AC mains between 110 V and 265 V into a stable DC 12 V output at up to 20 A. It is built for professional installations such as LED lighting strips, CCTV cameras and security surveillance systems. Overload, over-voltage and short-circuit protections are integrated, and cooling is handled by free convection.

Installers needing 12 V DC up to 20 A

The unit suits electricians and system integrators who need a compact, wide-input supply for 3528, 2835, 3014, 5050, 5630 or 5730 LED strips and IP cameras. It is not intended for applications requiring adjustable voltage rails, higher current than 20 A, or voltages other than 12 V DC. Buyers needing multiple isolated outputs or rack-mount form factors should look elsewhere.

DC 12 V 20 A regulated output

The single specification that decides fit is the fixed 12 V DC output rated at 20 A with overload, over-voltage and short-circuit protection. The supply accepts 110–265 V AC at 50/60 Hz, operates from 0 °C to 40 °C and weighs approximately 645 g. Connection terminals are L and N for AC input, GND for DC negative and V for DC positive, with an ADJ point for fine voltage adjustment.

Questions about this item

What screw-terminal connections does the unit provide for AC input and DC output?

The unit has L and N terminals for AC input, GND for DC negative, V for DC positive, and an +V/ADJ terminal for output-voltage adjustment.

How do I connect the AC mains and DC load, and which step is most often missed?

Wire live and neutral to L and N, connect the load to V+ and GND, then verify the ADJ setting before powering on — skipping the voltage check is the common error.

What environmental limits and protections determine when the supply must be replaced?

It operates at 0 to 40 °C with up to 95 % non-condensing humidity, includes overload, over-voltage and short-circuit protection, and should be replaced if protection trips repeatedly or output drifts outside 12 V.
