12V 20A switching supply for LED and CCTV

This unit converts AC mains between 110V and 265V into a regulated 12V DC output rated at 20A. It is intended for professional installations such as LED strip lighting, security cameras and CCTV systems. Overload, over-voltage and short-circuit protections are built in.

Free-convection cooling limits continuous load

The supply relies on passive free-convection cooling rather than a fan. Operation is specified from 0 to 40 degrees Celsius with up to 95 percent non-condensing humidity. Sustained full-load use in confined spaces or above the rated ambient temperature can trigger thermal protection and reduce available current.

Replaces open-frame or lower-current LED drivers

It upgrades from unregulated transformers or smaller drivers that cannot maintain steady voltage across long LED runs. The wide input range and regulated output eliminate flicker and extend LED lifespan. Buyers who need adjustable voltage beyond the fixed 12V rail or who require redundant hot-swap modules should look elsewhere.

Perguntas sobre este artigo

Which version should I choose for my LED strip project?

This model provides a single DC 12 V output rated at 20 A; select it when your total LED strip current draw stays within that limit.

What does the 20 A rating mean once the supply is installed?

It can continuously deliver up to 20 A at 12 V to power LED strips, CCTV cameras or similar loads without exceeding its rated current.

What input voltage range does the AC connector accept?

The supply accepts AC 110 V to 265 V at 50 Hz or 60 Hz, so it works on most mains voltages worldwide.
