Edac/Drobo Power Supply Fuse

[vletr]

Hello,

Looking for next steps on troubleshooting for an external power supply made by EDAC, model EA11011H-120. The power supply was dropped onto a tile floor and initially and briefly worked but the led power indicator light faded out and the power supply showed no signs of life since.

In disassembly, I found that the large capacitor had leaked and was reading open when measured. The fuse nearest to the AC in had also blown, with no continuity. I ordered a new capacitor and fuse and replaced both, but on power-up with no load the fuse immediately blew.

I'm curious for recommendations on what to test next. Photos attached, though I desoldered a couple other capacitors nearest to the large cap in order to test them which thus aren't in the photo. Both of those tested fine.

Re: Edac/Drobo Power Supply Fuse

when it was dropped it probably cracked a solder joint or 2,

but about the fuse,
check the bridge rectifier, the mosfet on the heatsink near the main cap, and those 2 small brown ceramics for shorts

and explain why you desoldered atleast 2 polyester caps!
