You are looking for the sixty.

So you are looking conventionally for a 50KVA transformer 480 volt input with three taps for 240 and 120 secondary outputs. It may have adjusting taps as well.

Or you can custom order a transformer with 240 volt input and 36 volt secondary output through either me or a local supplier, I don't know what your deal is there. I use the 36 volt in my furnace. That works out to two banks of three elements at 12V if wired in series.
What about welders? I thought I heard something about people using welders for their transformers.
