DC 48V 5A Switching Power Supply 240W AC-DC Converter Transformer for Brake Machine Industrial Automation CNC Stepper Motor and More [Upgraded Version]

Exactly what I expected, next day delivery and works very well

I was skeptical, so many negative reviews on PSUs , (Including this one). I already had to return a Digi.... brick style DOA. I tend to think PSUs are fragile, especially in transit, and at these voltages, more so. JoyNano DC 48V 7.5A Switching Power Supply- Arrived in new condion promptly. I plugged in, no arc at outlet, good, measured before anything else, 50.1v no load, I dialed back less than 1/8 turn to 47.5v, good, turned off to drain, then turned on, measured 44v then 47.4 no load, soft starting?, good. I connected my device and all good. Fan hasn't turned on but my load is slight, if quits Ill edit review.

My only dislike was the fact that it didn't come with mounting tabs to secure it ...???Other than that it works excellent !

Packaged nicely, got them in the mail very quickly. Quite happy with my purchase

Pretty bad, opened the box and the aluminum frame was bent in two places. Picked it up and felt like something heavy was floating in there, ended being the big toroid ... anyways, surprising as it was plastic wrapped and had the 'inspected' sticker on it. Being $40, didn't want to waste the time trying to return it, and managed to solder the toroid back on, tested, and appears to work, though the high side of the adjustment on thus 48v 10amp supply was 59v .. so hopefully it works when I put it in my machine under load....

I had to repair the unit myself After I repaired the unit It seems to be working ok but for how long I don't know?

Arrived with something loose inside rattling and knocking around. Only the fan came on when powered up, no green light. I was buying this to use with an Aiyama A07 amp. I sent this back and I’m now using a Drok 0-48v 10a adjustable power supply which works fantastic.
