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 been told that I cannot use a three-phase VFD to power the instrument. The feedback from the single phase pumps and the control elements will shut most VFDs down. Are any of your instruments compatible with my application? The total power consumption is slightly less than 4 kW and the maximum current is 16A. I basically need something that will convert 480 V 60 Hz to 380 V 50 Hz, but will also tolerate the single phase heating elements that operate from 220 V 50 Hz.
