Hi all, I have some high-power battery chargers which run on 480V 3 phase power. I need to be able to make them work in England, where I believe the standard 3 phase service voltage is 410V (please correct me if I'm wrong). These chargers can handle 50Hz instead of 60Hz, but they cannot work down at 410 V. So, I need a transformer which takes 410V and gives me 480V. Does anyone here know of a company which makes such devices? I'd be looking at around 20 amps in each phase. Thanks very much!
