    UPS Transformer

    Good morning, I just found this big transformer from an old small UPS, so I was wondering on how to use it, and how to understand its operation and wiring as well thanks in advance

    Looking at the thickness of that secondary winding it's going to deliver high current at very low voltage on the output. Is there any kind of printed info on it? I'd guess it's going to give 20 or 30 Amps at maybe 5 or 10 volts. What do you want to use it for? Maybe make a spotwelder out of it if you've got time for a project.

    It doesn't have any print, and still think about where to use it, any idea from your side?

    Didn't get the chance to see info, but what I saw is that it didn't have a battery in it, and its an old type.
