I recently installed a step up transformer to convert our 3Ø - 120/208V service to a 3Ø - 277/480V. It works like a charm, our service at the shop runs a little 'hot' ... typically 126/215V. I can adjust the taps on the transformer primary up to that and out comes perfect 277/480V.
However... I just acquired an older Solberga drill that I want to power up. The nameplate says 3Ø - 440V.
Our transformer, set on it's highest primary taps, still leaves us with ~271V-275V on each phase/leg and roughly 471V-475V phase-to-phase. What is the most practical way to lower the voltage to ~440V? Buck and boost? If so, do I need 3ea single phase buck and boost?
Thanks!
