Review on 💡 Anmbest Constant Current CC CV Buck Converter Module - 1.2-36V 20A 300W Power Supply with Short Circuit Protection by John Patterson

I really like this machine. It serves its purpose well, ie as a desktop power supply made from an old 30VDC power supply that was gathering dust on mine. The output is easily adjustable and stable. The warming is noticeable, but not excessive. It has a pair of relatively massive aluminum heatsinks. The I and O terminals are easily accessible, well labeled and ensure a reliable connection. I used tinned stranded wire ends to make the connections and they work fine. With a piece of adhesive foam on the back, presumably to protect against accidental short circuits; It's easy to remove when not needed. The plan is to 3D print a housing for this with easy access to the adjustment potentiometers and an integrated digital V/A display. I'm still considering turning on the fan, but it probably isn't necessary. I wish there was better documentation (okay, no documentation at all), specifically on how to use the constant current function. I would give five stars if it included proper documentation.
