Hello everybody,
My 220v 12v 1600w power supply just failed, my best guess is due to overheating, I wasn't at the place when it failed. Now I checked every component I could do with my dmm (caps, inductors, resistors, diodes, relay) and except for the 100c thermal fuse (edit: even that was doing fine) every item was OK, replaced the fuse but it still doesn't work. Its relay doesn't click and output is 0.00 volts.
Also, the filtering capacitors get charged up after I plug it in, so I think the bridge rectifier is also ok.
There's also a NCP1399 IC which the thermal fuse was connected to its SKIP pin, and I don't know any way to test this guy.
Any guesses which would be the cause?
I could post the pics if needed.
