Hi!
I have got one og those cheap Chinese SMPS from eBay. A 24v 3a. The annoying thing with it is that the transformer is squeeking like a rat having its tail trodden on. My attempt to reduce that noise was to put a larger capacitor on the line in. The original one is a 47u 450v. So I put in a 470u. That blews op the Fuse And three of the four rectifier diodes.
So my question is, why they blew up? Cant they cope with a larger capacitor?
Regards
Axel
