To operate a piece of hardware with a 480 voltage rating, you will be required to invest in a step-up 3 phase transformer. The phase transformer will increase the voltage rating from 240 to 480 to meet the requirements of your project. A rotary phase converter is not designed to adjust voltages. The input voltage for a rotary phase converter will be identical to the output voltage. On the other hand, a rotary phase converter can be used to enhance a single phase electrical input to a three phase electrical output.
