Burned out my DSP1550 RuiDeng power supply
« on: February 10, 2019, 02:42:02 am »
I was testing an ESC and brushless motor at about 10 amps, power cut off, the screen went white to black.

One of the fets under the fan leaked a couple small solder balls through the vias and it smells burned.

Is it likely there is more damage? I'd expect the screen and micro to still function. I checked the fuses.

I know Dave did a video but I think his failure was a little different.

Anyway, I ordered another one so at least I can compare the two when I get to troubleshooting.

I'm also going to look for a real bench supply - there is a no frills single channel keysight on craigslist for $180, seems like a good deal.
