Smooth, reliable three-phase power from single-phase lines.
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.
ROTO-LOAD CENTER® is designed for applications with 3Ø electronic equipment or systems with line-to-neutral circuits that
cannot be modified. Prewired and packaged specifically to reduce the number of field connections.
POWRSOFT® Rotary Soft-start Controller is designed to soft start Ronk rotary phase converters.Learn More
ROTO-CON® rotary converter provides smooth, reliable 3-phase power from single-phase lines. Best suited for operating motors that do not operate continuously at high load levels and for non-motor loads.Learn More
ROTO-CON® rotary converter provides smooth, reliable 3-phase power from single-phase lines. ROTO-CON Type D-1 is designed for applications with a single high starting torque motor or resistive loads with tighter voltage tolerances.Learn More
