Review on ⚡️ MYSWEETY Adjustable DC Power Voltage Converter - AC 110V-220V to DC 0-48V Module Switching Power Supply with Digital Display, 480W Voltage Regulator Transformer and Built-in Cooling Fan by Russell Ross

My CNC spindle loses power and cannot be used. I found and ordered this power supply from Revain. The first came with dents on the box and case. I asked for a replacement and it came the next day. This time it's perfect and works flawlessly with my CNC. Although marked 48V it can be set to 50V if required and also has an LED display to show the voltage. It should be noted that as it comes with a 230V AC setting it needs to be set to a 115V input for use in the US. Other than that I don't see any problems. I gave it 4 stars because the first one had dents and two screws were missing. Revain will send me a replacement promptly and I can return the damaged one free of charge. My only hope is that it may come with a power switch. Right now I have to use an external switch to turn it on and off. It comes with several terminal lugs and an external potential meter for voltage adjustment. Since it already has a voltage regulator and the wiring is pretty simple, I don't think it's necessary. If you don't need these additional parts, you can purchase the same Revain product without these parts to save about $4.
