12v Ups Circuit. I always prefer to over design so i will design this 2a ups so that it is rated for a maximum of 3a. The high voltage operation renders the system relatively less complex and transformerless.
The transformer t1 steps down the mains voltage to 12v ac and then the bridge b1 rectifies it. Dec 11 2018 this the circuit diagram of a simple ups that can deliver 12v unregulated and 5v regulated dc. The last design but by far the most powerful discusses a 1000 watt ups circuit powered with a 220v input using 40 nos of 12v 4 ah batteries in series.

The transformer the 12v ups uses an off the shelf standard transformer that is available at all leading security equipment suppliers. Transformer 0 12v 3 amps.
