An installation currently has two effects projectors and wishes to add a third. All three projectors are 240V. The two currently in use have this transformer Model T-1-81052 Acme AT1471 - Buck Boost Transformer - 120 x 240 pri - 12/24 secondary - 0.75kVA , to boost the voltage from 120 to 240. The transformer is identical to this one, and the core is potted, with just the eight wires coming out.
Unlike in the picture, on mine, all the wires are the same guage.
There is no 240V service anywhere convenient.
So I bought an identical transformer, ACME T-1-81052 Primary: 120X240, Secondary: 12X24. It has eight wires labeled H1, H2, H3, H4, X1, X2, X3, and X4. How do I connect the inputs and outputs to make this go from 120 to 240?
I tried looking at how the others were wired, but the genius who installed them some years ago cut off or removed the wire labels. I know this transformer is sold as a buck/boost, and is often used to step up 208V to 230V. None of the wiring diagrams provide for what I am wanting to do, but I know it can be done as the other two do exactly that.
Oh, by the way, in case anyone is thinking Consult a Professional Electrician, (normally very prudent advice), I did, and his suggestion resulted in 64V output when I input 120V. So I'm hoping [USER]STEVETERRY[/USER], epimetheus, Dionysus, et al can help me.
