What this adapter does

The KEHIPI PHEVOS unit converts 110V or 240V AC mains into a regulated 5V DC output rated at 8A and 40W. A physical switch selects the input range. It is built for 5V projects such as Raspberry Pi boards, CCTV cameras, WS2811, WS2801, WS2812B, APA102 and SK6812 LED strips, radios and general computer projects.

Installing and common issues

Mount the supply in a ventilated enclosure and set the input selector to match local mains before connecting power. Screw terminals accept stripped wire for the DC side. The unit includes short-circuit, overload and over-voltage protection (115%-135%) with auto-reset or fuse action. Typical problems are forgetting to flip the voltage selector or running cables too long for the 5V rail, which causes voltage drop at the load.

Who should buy this and who should not

Makers, installers and hobbyists powering 5V LED pixels, security cameras or single-board computers from a single 40W source will find it a direct fit. Buyers who need more than 8A of 5V current, who require a different output voltage, or who want a supply with a standard IEC inlet and detachable cord should look at other options.

Questions about this item

How can I verify the adapter is delivering 5 V 8 A after I wire it up?

Measure the output terminals with a multimeter under load; you should read 5 V DC and the connected project should draw up to 8 A without the overload protection cutting off at 115 % to 135 % of rated current.

What comes in the box and what must I supply myself?

The unit includes the switching power supply with a selectable 110 V or 240 V AC input switch; you must provide the AC mains cord, output wiring and any connectors for your LED strips or Raspberry Pi.

Which version should I choose for a WS2812B strip that needs 40 W?

The single 5 V 8 A 40 W model listed covers that requirement; no other capacity or voltage versions are offered for this product.
