KEHIPI 5V 40A 200W Power Adapter

5V 40A switching supply for high-current LED

This unit converts 110V or 220V AC into a stable 5V DC rail rated at 40 amps and 200 watts. It is built for indoor installations that demand sustained current, such as long WS2812B, WS2813, WS2811 or WS2801 pixel strips, CCTV arrays or security systems. The metal enclosure uses convection cooling through multiple vents, so it runs silently without an internal fan. Dual output channels simplify wiring for parallel loads.

Sustained 200W delivery with 15% voltage adjustment

Continuous operation at the full 40A rating is supported by pure copper inductors, high-performance transformers and dual electrolytic capacitors. Over-voltage, overload, over-temperature and short-circuit protections engage automatically to protect connected hardware during extended runs. The output voltage can be trimmed by 15% via the onboard adjuster to compensate for voltage drop across long cable runs. An input-voltage selector switch must be set to 110V or 220V before power is applied.

2.5 mm mounting holes fix the chassis in place

Four screw holes with a 2.5 mm diameter secure the 5.4 × 20.0 × 11.5 inch metal case to a panel or enclosure. The unit weighs 0.64 kilograms and operates from -10 to 50 degrees Celsius in 10–95% humidity. It is not rated for outdoor or wet environments and provides no isolation beyond the standard AC-to-DC conversion. Buyers needing weather-sealed enclosures, higher voltages or redundant hot-swap modules should look elsewhere.
