Lol nice to see that, I got a Yihua PS-3010D
It’s a 10A version without Low and High Amps limitation, I wrote something about it in another topic while I was testing the fan noise of my scope.
The power supply came out the box with burned plus banana plug inserts, they used some crappy 3A versions so I changed that to 16A versions, and the fan makes too much noise (it is always on).
There is a huge capacitor dangling around in the housing which they try to mount to the bottom with a tie-rap mount, but that was also loose of course.
Wiring inside is crap, there are 4 output transistors mounted inside the housing on a 2mm aluminum piece used as heat sink but it is not even close to one.
I just checked my phone there was some pictures of it which I took for my friend, I will post that below, also a movie with output noise on a scope.
I use the power supply for high current automotive lambs and other automotive things to test them out, so it is good enough for couple minutes using for me on not so fragile things.
But to be honest, I wouldn’t recommend this power supply to anyone who is doing some fine electronics projects.
I was going to review this power supply but I really need a bigger bench, I don’t have any room on my bench so I am heavily busy to make a new bench.
Anyways here are the pictures:
Sorry I guess my phone cam needs better focus
And I was testing its DC output noise here, you also hear the fan sound after switching:
