The massive peak in the left edge of the spectrum plot is definitely the 60 Hz essential. The big harmonic peaks the thing is show that my wall electric power right here isn't Tremendous-clear.

I have an APC Again-UPS RS 550G which I have been employing in my home Workplace for approximately a 12 months. It observed me through a several electricity outages for which I used to be rather glad. Even so, I've dropped quite a bit of time to an peculiarly high incidence of system failure in excess of the training course in the 12 months.
Having said that, if the utility electricity is not sufficiently protected against lightning, even that might not be more than enough to shield versus a serious lightning strike.

The opposite downside is that there's no computerized voltage regulation, so you will miss out on out on staying protected from electric power fluctuations.
While which is lots much better than the output we have been bring about count on by fixer1234's submit, it is not quite. Not just is there lots of wide-band sound and distortion on this UPS's output, Individuals two back-hitches the thing is on Each individual cycle can annoy circuits that think the AC input voltage usually increases or decreases steadily.
– Aryeh Leib Taurog Commented Jun 4, 2015 at nine:37 PSUs frequently either perform or Really don't; I have never observed or heard about one failing in a way the place it outputs the incorrect voltage. It could also likely be the first thing to fall short. I have hardly ever noticed a situation in which a surge fried a lot of inside components but left the PSU unscathed.
