Aclorol 5V 20A 100W Switching Power Supply 110V / 220V AC to DC 5V 20amp Universal Power Transformer Driver Converter Adaptor for WS2812B WS2813 LED Strip Pixel Lights CCTV

This has been running my Linux HTPC for years now. Clean, stable and reliable power. The PSU runs ice cold.

The input voltage switch is inside the cover, and there is a sticker saying "Don't open the cover". Fortunately I could see the switch through the cover holes and it was set to the correct input voltage. There is a POT to adjust the output voltage. I set to 5V and then started adding load. My PLC ran OK until I connected an LED strip, then my PLC smoked. I think the voltage jumped. I would not recommend connecting directly to digital circuits. It needs a voltage regulator. The power supply is lightweight and easy to connect AC cord and DC wires. 20A can drive a lot of LEDs.

Looks good. Works for what I needed it for.

I am using this supply to run some old electric tools which require 12 volts. It is very stable, and easy enough to set up (you have to connect a power cord and other wires). It is like a computer supply, in that it is just a metal box which is supposed to fit into existing equipment. There are no instructions with it, but you can find information about the set up on Youtube.

Product works as advertised. Warning: be careful not to connect the white lead of your power cord to the “live” terminal as depicted in one of the photos on the product description page
