A UPS is a transformer, a rectifier, a filter, a regulator, a battery, a charging circuit, a DC-AC inverter, and an AC sensor.

In order to construct a more concrete example we need to define some requirements. Do you have any in mind?

Thanks.

He gave you the stages, try and figure out what is what. A detailed overall schematic will be a waste of time as nobody probably has the model you are looking at.

I probably replace 50 UPS units a year, from 550-BEST 4 car battery models.

I would guess 9 out of 10 if not more are dead batteries.

What is it doing? Does it power up, see AC power? Or does it power up and beep? What brand is it. For $120 US (or less) you can have a nice new one.

I'm sorry but my extra sensory powers are unable to pentrate the fog that is preventing me from seeing the UPS in question. I think replacing the battery if you can is a good first start.
