![]() I hope that only the PCB where i found the 3.3V is damaged and i can get a replacement from Eltek. Next time i post here the question before i do action. The only thing you might want to add is end of charge disconnect. Are you familiar with those? Their efficiency is high and they are adjustable in both CC and CV. This project will not be easy, is it worth the effort and risk? The Meanwell LED supplies are easier and very robust. How did you determine the 3.3V was isolated? Do we have a schematic of the "rectifier" module? Probably don't need to go quite that far here, but one could. ![]() In most designs that doesn't fit the definition of a "fail safe component".įor a safety system generally two independent circuits and separate controls are required. They are SCR or FET based and they fail shorted. Regular solid state relays are generally not allowed in safety systems. I was involved with a number of safety systems (accelerator controls, X ray machines, etc), there are safety rated relays, and they tend to fail open if properly selected for the application. At least the one I have wasn't cheap, but I bought it new. Sorry to hear about the "rectifier" failure. ![]()
