Title: Rigol DP832 service manual
Post by: jmibk on September 23, 2019, 09:02:41 am
I have some issues with a Rigol DP832 power supply, after a collegue tried to charge some batteries and switched the two outputs in parallel.
After he connected the batteries with false polarity (  |O  |O  |O ) the magic smoke escaped.

So a schematic would be useful to repair the thing... Anyone?

Check fuses, FETs, etc. Daves original repair video has some of this as well.
There is a service manual for DP1308A, but yeah, no schematics, I don't think you will find any.

This Rigol document (PDF) will help you understand what happened, and show you how to avoid this issue in the future.
