My power in (from a 10hp rotary phase converter) is 229/245/233; working on getting a manual for the machine. This is not a 208v transformer as it has a data plate on the transformer itself that says "230/460 in, 70-80v out", everything I've read says I need 63 v max out....do all the other t2's out there say 54 to 63 v out on the transformer data plate? will the machine automatically blow transistors with 72v at t2:11/12 if I replace them even if all I do is jog the machine with no load, not cutting? I would like to see this thing at least move before I address the voltage issue if possible, if not I will have to figure out how to reduce the input voltage to 187v to get my 76v (my at the moment highest voltage of the 3 outputs on t2) down to 62v. this seems very strange and I would have said something was wrong with t2 if it wasn't placarded 70-80v out. I'm measuring this t2 output voltage with the machine stationary I assume...I'm obvously not an electronics wiz(!) but maybe the voltage drops to the recommended range when there is a load, which I am not able to apply because the machine is not moving?
I'll order a set of transistors and manuals, do you know the value of the little diodes?
