The fan on the Meanwell Power Supply is not spinning but the power supply is otherwise working normally. Is the fan thermally controlled or just not working? Thanks.
Yes, it is thermally controlled: See datasheet: https://www.meanwell.com/Upload/PDF/LRS-350/LRS-350-SPEC.PDF page 2, about halfway down: Function: FAN: On at 50degC, off at 40degC
