This is now well-liked even in The most affordable UPSes mainly because it can take advantage of factors now incorporated. The main 50/sixty Hz transformer utilised to convert between line voltage and battery voltage requires to supply two a bit distinct turns ratios: One to convert the battery output voltage (typically a several of 12 V) to line voltage, along with a next 1 to transform the line voltage to a slightly greater battery charging voltage (such as a a number of of fourteen V).

Here is where by the enjoyable starts, simply because you future have to look at just how long you wish the UPS to run if the power goes - which can take two paths...
