That's a brown out dude.
Some switching power supplies might deal with that. Probably equipment
dependent, but I would not expect most things to work that low.

So Ohio's power grid is getting taken advantage of from behind. The
snow in spring I guess is just too much.
Power company is having issues and our sites been without power for a
bit over 2 hours. I drove out there to take a look at things and the
lights did come on, but they buzz and only partially illuminate. The
batteries are at charging voltage. I measure the AC input at our
rectifier (AD-155B, spec below) at 67 volts. That seems like it's
working perfectly fine - is that possible??? The two 12v batteries
are charged at 27.3v (set on the unit). There's no way after 2 hours
they'd supply ~80 watts and still be >24v without getting power from
the utility.
Is it as simple as the AD-155B works at 67 vac?
