This happens to be well known even in The most affordable UPSes as it can take advantage of factors by now involved. The key fifty/60 Hz transformer employed to transform concerning line voltage and battery voltage demands to provide two a little bit distinctive turns ratios: Just one to convert the battery output voltage (commonly a numerous of twelve V) to line voltage, in addition to a second a person to convert the line voltage to a rather increased battery charging voltage (such as a a number of of 14 V).
The big peak within the left edge of the spectrum plot will great site be the 60 Hz essential. The big harmonic peaks you see show that my wall power here isn't Tremendous-clean.
