Johnson Controls 8 NET 16 power supply repair - help needed
« on: April 19, 2019, 10:03:00 am »
Hello,

I've bought a Johnson Controls power supply to mount in a 19"-Rack for Eurocard-type PCBs. I tried to switch it on outside of a case, which should work, but the only thing it did was creating some sparks and blowing the fuse. Typical magic smoke.
Taking it apart I found out that some SMD components are burned beyond recognition.
Does anyone have a similar power supply or even schematics of this one to help me fix it?
