That's a funny spec... I don't think that's standard for anyone.
Most of the world uses 220-230v, and IIRC, 50Hz is more common than 60Hz.
The USA being the big 60Hz fan, although I'd have thought they'd be terrified of the idea of the 240 volts.
I hope they at least have an option for 50Hz, or all our European desk fans are going to get turbo charged! (AC induction motors).
