Rigol DP832 Random Reboots
taydin:
Just saw the reboot on my DP832A. I have this unit for several years, and I think I saw this spontaneous reboot only two times, including this latest reboot. Firmware version is 1.13.00.1
When this happened, only CH1 was on, set at 12V and supplying around 150 mA current. Temperature is 30 degrees celsius right now, after reboot.
I don't know what the status is with the heatsink, I will check this.

I was using my DP832 to charge a battery, came back a few hours later and it turned off channel 1.
OVP or OCP were disabled... So I guess it did a reboot.
Do we know the cause, or is there a fix? A power supply that reboots isn't very reliable imho.
Smokey:
Bummer. My DP832 just starting this whole reboot thing. Happens intermittently now about every 20-45 seconds. I've had it for a couple years with no problems until now. That sucks.
Just as another data point, I outfitted all the technician benches at my last place with these supplies. Probably around 10 in total, doing daily work in a production environment. Out of the original order, one unit had this reboot issue out of the box. We sent it back for a replacement and had zero problems with any of the supplies since.
:EDIT: Its not one of original batch with questionable linear regulator.
Smokey:
Well shit. That went downhill fast. I was just about to post that I have the 1.14 firmware and it got worse.
Within the day it went from rebooting once every hour, to every minute, and now it's mostly in an infinite reboot loop where as soon as it comes up it reboots. I can hear the fan spin up sometimes, but not every time.
Of course this happens when I'm in the middle of an actual project. Fun.
