Hi there, no its not a production item, just a homebrew psu. But as the other capacitors temperature are or seem ok tested with a thermocouple and circuit heavily loaded, I will keep them in and watch and see. It was a sloppy mistake, I should have looked closer into the first blown fuse, maybe it would have prevented and venting of capacitors. Peak would be 20 Volts DC at 15 Amps on the capacitors string, continuous 50% duty cycle more like 8 - 10 Amps, same voltage.
