I want to repair a 27VDC (MPS-45-27) power supply but cannot find any schematics. Already bought a new one but would like to play around with the old one. Have looked and looked for it but no joy, any ideas?
This block diagram is probably all you are going to find. You will probably have to do what the rest of us do, draw out the diagram. You havent said what is wrong with it? You start by checking the mains fuse on the board, then move along, if the fuse is blown check for shorts on bridge rectifier& power switching device & capacitors.
