we play with different stuff out here..
Graham its 1.732.. thus the near doubling of power rating of the machine.
Use 60 hp drives for 50 hp water wells and it converts on 480 just fine..
same with pumping units. drive is rated at 30 hp for 25 hp motors.
Sinner and Brandon. Cost I was thinking was for bigger stuff like we use plus cabinets.
Lee, its all in the programming. just needs a or b phase shorted to the 3rd input on drive to see a leg there, and programming of the vfd will do what it needs to to create 3 phase..
Only reason we use them out here is for the conversion process, but we use a bit bigger..
still cheaper for motor style phase converter
