This has grown to be common even in the cheapest UPSes mainly because it requires benefit of elements now involved. The main 50/sixty Hz transformer applied to convert concerning line voltage and battery voltage desires to supply two somewhat different turns ratios: 1 to transform the battery output voltage (commonly a a number of of twelve V) to line voltage, as well as a next one to transform the road voltage to a slightly greater battery charging voltage (for instance a several of fourteen V).

The explanation is usually that pip listing --outdated outputs a listing of each of the out-of-date deals Within this format:
