Side view? You have peaked my interest
Nope, only the one module on the massive heat sync the diagram shows two , maybe they are internal? What is it for?That module is Transistor pack Half bridge drive module.
Are there two of them? need two of them for full bridge drive topology.
What is the model of this UPS?
Boat anchor.I guess it is a MASSIVE inductor...
Only two wires on it.
Winding appears to be solid #6 varnished flat conductor.
Wood core, iron cage.
Weighs about 40Lbs...
I'm thinking door stop.Boat anchor.
That's my guess as well.. If those are the only 2 leads going into the thing, Then most likely a big chokeIs it a choke to limit inrush current?
