I am trying to run a European instrument in the United States. The instrument consists of a three phase turbine and a three phase pump, and two heating elements that are single phase. The turbine in the pump is designed to operate on 3-phase 380 V, 50 Hz electricity. The heating elements are wired in such a way that they utilize 220 V, 50 Hz electricity. The problem is that our power in the United States is three phase 480 V, 60 Hz. This machine was built in the 1980s and is not compatible with 60 Hz.
I have three appliances that were purchased in Africa 240V 50Hz and would like to use them in the USA 120V 60Hz power grid. They are a gas range with electric oven, freezer and two refrigerators, one double door with freezer and the other single door refrigerator. They are in storage so don't have exact wattage requirements. Can you suggest which of your frequency/voltage converters I should consider?
My wife and I purchased a new washing machine in Germany (230V 50 Hz) while we lived there and recently moved back to the US (110V 60 Hz). We received our new washer in our crate shipped from Germany and I purchased a power converter. Problem is the Hz in incorrect and the washer does not operate correctly due to the onboard computer needing 50Hz. Would it be cheaper to purchase a new washer rather than a Hz converter to run the machine?
