Hi Piclisters,

I have a project at work that I need to test while powered from 120Vac 50Hz.
All I have available in the USA (Cleveland, Ohio) is 60Hz. Does anyone have
any clever and inexpensive ideas for how to generate 120Vac 50Hz? I need
about 4 amps to do my testing.

So far my thought is to buy a "Modified Sine" inverter ($100) that runs off
12Vdc and produces 220Vac at 50Hz. Then I could step down the 220Vac using a
transformer (which we already have). It's not very elegant, and not ideal,
but this is only needed for a few days of testing and then will probably sit
on a shelf for 20 years getting dusty.

Anybody have any other ideas besides a really long extension cord to a
country that uses 50Hz.
