be rewired to operate on 220 3phase, or do i need a stepup transformer and what rating |

I have a 1966 10ee that is set up for 460 volts. Prior to its
delivery I contacted Monarch to see what needed changing to get down to 230. The helpful tech send me a fax copy of the schematic and indicated where changes needed to be made. He said that the two filament transformers might need to be replaced, and they were a couple hundred dollars each. Not to mention, there are two shunts that need to be custom made for the lower voltage. After I looked at the job and the cost, I got cold feet. Long story short I bought a nice new 7.5kv step-up transformer (about $250) and run the machine on the 460v for which it is configured. Runs real nice. You might be able to find one cheaper, but I didn't want to play russian roulette with this one. Neil P.S. Either way, if you care, you'll need to resolve how to run the 3-phase coolant pump. A small VFD or static convertor would do fine. I haven't run mine yet...

For most 10EEs, the best course is a 240:480 transformer. There is more to it than the two filament transformers (Modular) or the filament transformer and field anode transformer (WiaD). The C-H contactor, the pilot light transformer and the work light transformer, for example. |
