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.
POWRSOFT® Rotary Soft-start Controller is designed to soft start Ronk rotary phase converters.
Learn MoreROTO-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 MoreROTO-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 MoreROTO-CON® Type CP has been specifically designed to operate a wide variety of center-pivot irrigation systems. They are easily installed, require minimal maintenance, and will give you years of trouble-free service.
Learn MoreROTOVERTER® tap adjustments give you control over all three phases for balancing currents. Type C ROTOVERTER® models are recommended for multiple loads of varying horsepower ratings up to 100 HP.
Learn MoreROTOVERTER® tap adjustments give you control over all three phases for balancing currents. Type D ROTOVERTER® models are recommended for applications where a single load (of either single or multiple motors up to 42 HP) is operated and for non-motor load applications.
Learn MoreROTO-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.
Reliability and safety of electrical systems have never been more important. Ronk's American designed and assembled products are durable, efficient and last for decades.
