Lasever Power Supply ground issue
Recently I have had my projector disassembled to replace a failed Scanner amp board. I took this opportunity to chase down a ground fault potential, measured at 4.2 VDC I had between where the lasers heads and drivers are mounted and the level where the power supplies are located. I should note that I have a three (3) level design…each level being an Aluminum plate.
The leakage is sourced from BOTH Lasever Green and Lasever Blue power supply. See the attached pics. My bet is that the insulation between the power Mosfet and PS Aluminum case is split. The Mosfet and case are now in contact…causing the problem ( Buffo also sez this is likely).
My fix was to electrically isolate the PS mounting plate from the Aluminum bottom level plate. I used 8-32 Nylon bolts and 1” Nylon washers to secure both Power Supplies. This is one way to do it. I suppose you could redo the Mosfet insulation….but I went for a quick and sure fix. If you have any Lasever Power Supplies…you may have a ground issue. See pics of the Green PS interior and the bolt/washer combo’s securing the Blue Laser PS.
