12V DC Power Supply 30A AC 96V-240V Converter Adapter Universal Regulated Switching Power Supply 12Volt 360W LED Power Supply for LED Strip,CCTV, Radio, Computer Project (12V 30A 360W)

its smelly when running like that distinct chinese electronics smell but very powerful. the fan is a nice touch but a bit loud . it delivers a consistent voltage about to 65% load then it starts to sag a bit. im seeing around a .3 to.5 volt sag at near full load. which is acceptable for my usage as i dont load it fully often or for very long. the next one is going to power a 3d printer so service life will be tested thoroughly then.

I use this power supply to power a 12v agricultural spray pump. Mounted it in a car battery box with a 35amp breaker and a cooling fan. Power leads go to the pump. The pump and tank are mounted on a pallet that stays in one spot and never moves. Works better than I hoped for

Works as advertised. Cooling fan is slightly loud but tolerable.

I bought this power supply as an experiment. I use it for amateur radio work, and it does a great job for that. It's had no issue putting out the rated power, it gets warm, but not hot, and was easy to work with. The only complaint I have is that it puts out noise in the 80m/3.5MHz band. The noise is comb shaped, and not broad band leaving a lot of the band open. It's a pain to work around, but it can be done. On all the other bands I've tested including 40m/7MHz, 20m/14MHz, 10m/28MHz and 6m/50MHz it's quiet. Even after the expense of putting it in a case, adding connectors, circuit protection and a meter, the whole project is still about half the price of comparable power supplies made specifically for amateur radio.

Needed these for an already active led light setup, was as easy as copying the wire setup from the old device.

It provided plenty of power but the EMI was so bad that a Digital Video Recorder on the same circuit was unusable. Pick another one.

Works great to power up my HAM radios on 12v. The adjusting screw allows me to fine tune the voltage to exactly what I want. My radios like 13.5 to 13.8 volts best so that is where I have it set now. Using my 25 watt radio heavily, I get very little heat out of this power supply. I just wish they would build in a digital volt meter so I could see at a glance what it is putting out. I have added a cheap voltmeter to the output side, but it would be nice if it was included.

I bought this power supply for my Anet A8 as a bigger replacement for the stock 20A and wow did it make a difference. So far, I’ve been using it for about a month and have had no problems yet EXCEPT for the fact that when it arrived, there was something loose and rattling inside. My friend had also purchased an Anet and opted for the same power supply from the same seller but his problems were worse. He had an entire electrolytic capacitors come lose off of the board. This was found right after unboxing it. I was fortunate enough to be able to orient and re-solder it back in place. His unit operated perfectly after that. Just be warned that things may be coming loose in these and inspect it before you install in anything.
