KEHIPI 20050 Adjustable Power Adapter

The KEHIPI 20050 is a buck converter that accepts AC 110V or 220V input and delivers a continuously adjustable DC output from 0 to 12V at up to 17A and 200W. An integrated LED display shows the set voltage with 0.1V precision. A heatsink and temperature-controlled fan keep the unit cool under load.

Suitability and limits

This adapter suits hobbyists, technicians and installers who need a bench-top or fixed-mount supply for 3V, 5V, 6V, 9V or 12V loads such as CCTV cameras, RV accessories or lab prototypes. It is not for buyers who require a regulated current limit, remote sensing or programmable voltage ramps. The fixed 17A ceiling also rules out applications that demand higher peak currents.

Deciding specification

The single figure that decides fit is the 17A maximum output current, which cannot be adjusted and must exceed the connected device's draw. If your load ever needs more than 17A, this unit will not suffice.

Questions about this item

What AC mains voltage must I have available to run the KEHIPI 20050?

The unit accepts AC 110V or 220V input; set the selector switch to match your local mains before powering it on.

Will the adapter safely power a legacy 5 V device that draws 10 A?

Yes — the output adjusts down to 5 V and the 17 A limit covers a 10 A load, while overload, over-voltage and short-circuit protection guard the older hardware.

How can I confirm the KEHIPI 20050 is delivering the voltage I set?

The built-in LED display shows the actual output voltage in 0.1 V steps so you can verify the setting at a glance.
