Richard: Your electrician may well have the best solution. A 60 Hz to 50 Hz motor generator set is a common solution to your problem.
There are also solid state power converters available. In particular, Panel Components Corporation in Oskaloosa Iowa sells at least three models. Their Model 85510620 will handle a maximum of 1250 VA, which may be enough for one of your devices, but not four. The cost is about $3500, which you can compare to the MG approach. They will also rent on a monthly basis. Phone is 515 673 5000, fax is 515 673 5100. Consider this: 1) you may want to test at 50 Hz plus or minus a few Hertz, so the MG must have a variable speed drive. 2) you may want to test at 220, 230, and 240 volts, and plus or minus 5 to 10 percent about each. So you will need a big Variac, or tapped transformer. I hope this helps some. Jack Jacob Z. Schanker, P.E.
