This is becoming popular even in The most cost effective UPSes since it takes benefit of parts presently bundled. The principle fifty/60 Hz transformer used to convert between line voltage and battery voltage wants to provide two try these out a little bit diverse turns ratios: 1 to transform the battery output voltage (usually a various of 12 V) to line voltage, and also a next one particular to transform the line voltage to a slightly higher battery charging voltage (like a multiple of 14 V).
