Unholy relay wiring
These two relays have the same switch state when the whole power supply is of or if it is in offline current set mode. If the control logic looses power (blown fuse), the relays internally short + to - and all the power gets pumped into the power transistors. A lot of heat...
I thought fuses were used to make stuff safer, but here... Once the fuse for the control logic has blow, 75W get pumped into the heatsink. I call that a possible cause of fire and or burned fingers. I don't want to think about that it was running in this condition for several hours - unnoticed.
