This is becoming well-known even in The most affordable UPSes since it usually takes advantage of factors already involved. The key fifty/60 Hz transformer utilized to transform in between line voltage and battery voltage desires to supply two somewhat distinctive turns ratios: A single to transform the battery output voltage (normally a several of twelve V) to line voltage, plus a next 1 to convert the line voltage to a slightly bigger battery charging voltage (such as a many of 14 V).
When you are creating a Computer, and this is an element of one's setting up procedure, Examine our power materials guideline in addition.
