In US, I think everything is 60Hz. But I mean 208v single phase.
(Which is what you get when you combine two 120v single phase legs out
of three phase, I believe. I am not an expert on AC...)

I have even been looking at USB HD AC adapter and all other odd ball
equipment and I always see the label say "100~240v AC". Dell's old
rack mount monitor/KB from 5 years ago even supports 208v (Just wrong
connector.)
