Rotary Phase Converters

Smooth, reliable three-phase power from single-phase lines.

Ronk Rotary Phase Converters for Smooth, Balanced Power

ROTO-CON and ROTOVERTER are usually recommended for the operation of a group of motors, or motors with considerable load variations. Use of a single converter in multiple-motor applications can result in lower initial cost and better load flexibility.

ROTO-CON can also be used to power resistive heating loads. ROTO-LOAD CENTER, which uses a rotary converter, is usually recommended for rectifier or electronic loads, such as CNC machine tools.
