RONK Static Phase Converters For Balanced Power
Autotransformer-capacitor type static converters are generally recommended for constant load applications, like most fans or pumps, with one or two motors. ADD-A-PHASE® offers very good starting torque, high efficiency, easily accommodates automated controls, and allows operation of the motor at its rated load.

RONK Static Three-phase Converters
ADD-A-PHASE® Type S – is our standard ADD-A-PHASE® static three-phase converter for most pump, air compressor, and fan and blower applications. Single motor applications only.
ADD-A-PHASE® Type AA – static three-phase converter is designed to handle loads for hydraulic elevators, balers and compaction equipment.
ADD-A-PHASE® Type HD – is designed for critical use motors, community warning sirens and valve operators. For equipment that must operate under every condition.
ADD-A-PHASE® Type SAC – is designed for most commercial air conditioning systems.
ADD-A-PHASE® Type SUB – is designed for deep well submersible pump motors and submersible wastewater pump motors.
ADD-A-PHASE® Type K-Duo – is designed to operate multiple motors to their full load rating and normal overload.
ECONO-PHASE® Shifter Type PS-OF – is a cost-effective, high efficiency power converter for popular use in pump jack application where Design D high-slip pump jack motors are used. 240V and 480V input and output units available.
RONK Rotary Phase Converters
POWRSOFT® Rotary Soft-start Controller is designed to soft start Ronk rotary phase converters.
ROTO-CON® Rotary Phase Converter Standard Type P 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.
ROTO-CON® Rotary Phase Converter Standard Type D-1 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.
ROTO-CON® Center Pivot 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.
ROTOVERTER® Type C 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.
ROTOVERTER® Type D 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.
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.
