Trying to help a mate who services industrial equipment get this SMPS going again, otherwise the whole machine is a write off. Replacement boards not available from supplier.
This is an industrial power supply from a commercial machine; I think it's a dishwasher. Lightning strike. Mt mate had a first go and assumed it was diodes or caps that had failed. He said the coupling capacitor had actually melted the solder pads.
Measurements with meter showed nothing seemingly failed on the primary side other than the big electro which seems to be reading low. Very suspicious about the transformer, which when you look very closely (not visible in pictures) looks like there could be a burn mark through the yellow plastic insulation. I'm making an assumption of shorted turns. Which caused the primary side to overheat as it was driving into a shorted load.
Anyway, would like to replace the transformer with either a direct replacement or substitute transformer. It has a part number (?) EPCOS 4310 P8910. Google search doesn't throw up a direct match anywhere.
Was thinking I could maybe substitute a small transformer from the 5V supply of TV SMPS I have hanging around. Any clues as to the specs I should be looking at trying to emulate?
