in NA the standard voltage is 115v if its a little higher or lower its not a big deal, ie +/-5v. i would not concern your self specially on the slightly lower side. if it goes much lower or higher I'd contact your provider.
What is the lowest voltage acceptable ?
I live in an apartment building and the AC voltage is usually 121 VAC. Lately with the hot weather Con Edison has had problems in Northern Queens , New York. My voltage has been lower and fluctuating between 119 and as low as 109. Right now it’s 115. What is the lowest to safely power my system?
