JOYNANO480W Switching Power Supply 24V 20A AC-DC Converter Transformer for 3D Printer CCTV Surveillance LED Display Industrial Automation Stepper Motor and More [Upgraded Version]

This is my CNC go-to power supply. I have several.

It works very well for my 3D printer. Only issue is the fan is very loud and always on. It would ne nice if it sensed load or temperature to control the speed.Update, because I want to leave this power supply always on but not leave the fan screaming when not needed I pulled the cover (which has big letters saying the fan is thermally controlled.) The thermal controller was not populated and was bypassed to be always on. If they are going to cheap out and exclude the temp controller from the fan they could at least skip on the cover stand that says "NOTICE: This power supply is built-in fan on/off control circuit. fan automatically works according to working temperature."Anyway... if you wonder why the fan isn't thermal controlled its because the didn't install the components.

Works great, would buy for other projects

It hums all the time. It didn’t do it at first but now it is. Even when the lights are off it’s humming away.

worked Great thanks

Would have been nice to see a mounting template, or at least spec drawing of mounting dimensions; other than that, this seems to be ok so far. Haven't pulled more than a few hundred mA out of it yet, but it seems stable. The voltage adjust trimpot is a bit awkward to reach, but not terrible.I'd recommend this, especially for the price.

Thanks

Power supply works as listed but the cooling fan is very loud and cycles on for 20 seconds and then off for 40 seconds. Do not install in living area.

Avec cette pièce j’étais heureux de faire mes modifications une machine à souder qui était possible de réparer merci cinq étoiles

Just as Advertised

Für Netzteile dieser Bauart gibt es viele Hersteller, leider meist in sehr durchwachsener Qualität. Nach einigem stöbern hab ich mich für dieses Netzteil entschieden. Es soll in einem Geeetech A30 als als Ersatz für das defekte Original-Netzteil zum Einsatz kommen. Der erste Eindruck bezüglich Qualität nach dem Auspacken ist sehr gut. Das Netzteil kommt in Folie eingeschweisst und in Umverpackung plus einem Datenblatt. Kein losen Schrauben zu hören, wie das häufig der Fall ist, auch das Finish macht einen guten Eindruck, was auf ein sorgsame Herstellung schliessen lässt. Beim einem Ersten kurzen Check meisterte das Netzteil seinen Job problemlos. Wunderbar :)

Non fonctionnel pour la u20Erreur de ma part

Si è rotto dopo poche settimane di funzionamento si è bruciato il fusibile 220v 5A che alimenta il primario, non ho aperto la griglia per non rimuovere la protezione e perdere la garanzia inoltre il fusibile è saldato sulla scheda dell'alimentatore.
