Yes, the PP20 power pack can be operated at 220VAC and 50 hz. Frequency has very little affect on the operation of the power pack, but the voltage does have a large effect. The PP20 is designed to operate at 277VAC, so operating at a lower voltage will lower the current output on the low voltage side.
