Hello anyone,
I've got a faulty power supply from and outdoor LED unit that I'd like to try to repair. I replaced this power supply with one from a working unit to test and this one definitely has a problem. The unit is an outdoor LED PAR with 48 LED's, 12 red, green, blue and amber and the working power supply that was tested outputs 48VDC and 12VDC from the terminals. The defective power supply outputs 48VDC from both terminals so I believe it's overdriving the main circuit board with the LED drivers. I'll be grateful for any assistance. I uploaded a picture of the power supply and a drawing showing the part numbers for the main rectifiers etc. I dabble a bit in repairs but as far as identifying parts by name, well..........
Thanks,
