Rigol DP832 Random Reboots
skrap:
Got a new one and this one is flawless, at least so far ;-) All the design quirks are still there of course but I can't really say I mind them much at all actually. Latest hw and software revisions really makes this a nice powersupply indeed.
At least until the dreaded reboot rears its ugly head once again... but hopefully no more.

At least the large heatsink but I can't confirm the new mosfets or not, firmware is the latest version and calibration was done in June. The supply works really well and is within spec. when it doesn't hang or reboot but this typically happens within a minute now no matter if the outputs are on or off. Since it's very repeatable I guess something on the digital side is overheating for some reason.

what is the latest revision ?
skrap:
It's DP8C 2.20 I beleive, I'm not sure about the number but it's the one with new heatsink and larger mosfet.

I just got a message from a friend who bought my 2016 (post regulator update) DP832 a couple months ago. He says it get stuck in a reboot loop especially when cold. It warms up then stops resetting and begins to work. Anyone see this?
RoGeorge:
If any electronics are doing strange things only when cold, then check for bad capacitors with high ESR.
