This has become preferred even in The most cost effective UPSes as it normally takes advantage of factors previously integrated. The leading 50/sixty Hz transformer applied to transform in between เครื่องสํารองไฟ apc line voltage and battery voltage requires to supply two somewhat various turns ratios: One particular to transform the battery output voltage (normally a various of twelve V) to line voltage, and also a 2nd a person to convert the road voltage to a slightly increased battery charging voltage (for instance a multiple of 14 V).
If using power cords to unfold UPS power across a substantial place then anything apart from a pure sine wave can actually distort worse on account of impedance outcomes alongside the power cable.
