What this adapter delivers

The KEHIPI A12V16.5A converts 110V or 220V AC input to a regulated 12V DC output capable of 16.5A and 198W maximum. A built-in selector switch sets the input voltage before power-on. The unit includes automatic overload, over-voltage, thermal and short-circuit protection. It is rated for indoor use only.

Who should use it and who should not

Installers powering 12V LED strips such as WS2811, WS2815, 5050RGB or 5630 types, CCTV cameras or security systems will find the voltage and current a direct match. Buyers needing outdoor-rated enclosures, a bundled AC cord, mounting hardware or an on/off switch must source those separately. Professional wiring by a qualified electrician is strongly advised.

Fitting it into a project

The white metal case measures 20.7in x 10.24in x 5.3in and weighs 30 grams, with a porous shell for passive cooling. Output voltage can be trimmed from 11.5V to 12.5V to compensate for cable drop. To maximise lifespan, run the supply at no more than 80% of its 198W rating — about 158.4W continuous. No power cord or installation instructions are included.

Questions about this item

What input-voltage selector must I set on this 110V/220V switchable unit before connecting it to my local mains?

Slide the built-in selector to 110V or 220V to match your local supply before powering on; the adapter ships set to 220V.

Will my existing 12V LED strips that draw up to 16.5A work with the ±10% adjustable output of this supply?

Yes — the output can be trimmed from 11.5V to 12.5V, so any 12V strip rated at 16.5A or less will operate within specification.

How can I confirm the adapter is delivering a stable 12V after installation?

Measure the DC output with a multimeter; it should read between 11.5V and 12.5V under load, and the metal case should stay warm but not hot thanks to the built-in thermal cut-off.
