I have some automated pet stuff in my house. There were 2 power outages 2 days in a row. After each one, the pet electronics refused to turn back on even if I unpluged and replugged the power brick from the wall outlet side. They would only turn on if I unplugged the power brick on the electronics side and plugged it back in.
This is kind of a pain because of the cat stuff we own is a litter robot and where it’s placed is really tight. It’s a huge hassle to access the back side of it to unplug the power brick.
So my question is, why does this happen and are there any workarounds so I don’t need to unplug the power brick when it happens?
It’s hard to tell without a circuitry layout, but my best guess is that there’s probably capacitors in the power brick acting as an electrical filtration for the motors to make them operate smoothly and reliably.
The capacitors are probably discharging some electricity that are keeping some circuit protective device alive. Unplugging the power brick is probably the only true way to completely remove electricity from the unit.
Oh that does make sense. So if I unplug the unit from the wall outlet side and just wait it should also work? In theory I just need to wait long enough for the power brick to discharge completely. I’ll try that next time. Thank you!
