This happens to be preferred even in The most affordable UPSes since it takes benefit of elements currently included. The most crucial fifty/60 Hz transformer used to transform in between line voltage and battery voltage requirements to deliver two marginally different turns ratios: A person to transform the battery output voltage (usually a various of 12 V) to line voltage, in addition to a 2nd one to convert the line voltage to a rather increased battery charging voltage (for instance a several of fourteen V).
