Universal Regulated Switching Converter - SUPERNIGHT 12V 30A DC Power Supply Driver Adapter for 3D Printer, CCTV, Radio, Computer Project, Industrial Automation, LED Strip - 360W AC 110V/220V Transformer Review

I bought this power supply to power my 12V LED strips. In my experience, the horse power that came with my tapes was not sufficient for this task. From a pure performance standpoint, this device seems to perform well. My headlights now work as they should. However, it is very noisy when the fan kicks in, which is most of the time since I'm running it near its rated power.

So the price was right, I've bought one of these before - that's for another 3D printer. The overall packaging is as expected and I took it as it is UL CE and SA certified - but that's unlikely - half…

I suggest you take some time to take it apart and check the soldering work, make sure all points are touching. Helps wipe away the factory thick heatsink paste smeared on the aluminum walls and replace it with something more thermally conductive (which is pretty much it) if you want the device to run cooler and last longer. Cheap CPU lube works great. I used a spare computer cable with one end cut…

I'm a radio amateur. I have read reviews from other radio amateurs regarding the noise generated by this power supply. But for the price I still decided to give it a try. Of course, PS produces hash and tone spikes on all ranges. However, after some research and measurements I was able to get rid of most if not all of the noise and the like. First and foremost, the DC mass floats. It is not connected to AC ground. This is normal, but a major source of noise. To give the PS an RF path to ground…
