The PHASE-SHIFTER is the ideal converter for most single motor machines, featuring good motor performance and low converter cost. The PHASE-SHIFTER delivers starting and running current on all three phases to provide high motor starting torque and continuous loading up to 70% of the motors rated output. These features are ideal for mills, lathes, drill presses, punch presses, sanders, grinders and many other machines. The PHASE-SHIFTER may also be used for motors operating heavier intermittent loads, such as hoists, hydraulic presses, and home workshop equipment.
The PHASE-SHIFTER is built as rugged electrical equipment - not an add-on "gimmick". All sizes are supplied in aluminum enclosures suitable for indoor and outdoor mounting, with ample room for wiring. All components in the converter are designed for long, trouble free life.
A special PHASE SHIFTER has been designed for oil well applications. It can be used with 1200 or 900 RPM Design D motors.
Often referred to as a "static" phase converter, the RONK ADD-A-PHASE® is actually a full load, autotransformer-capacitor style converter. Many misconceptions are construed toward the ADD-A-PHASE® because of this. The idea that the ADD-A-PHASE® is limited to one motor load only is absolutely false. There are ADD-A-PHASE® in operation now operating up to 6 motors, at full load, from one single unit.
The RONK ADD-A-PHASE® is still the most efficient phase converter manufactured today. The design allows adjustment to provide balanced three-phase power at any motor load up to the converters rating. The high efficiency (97%) and low standby losses make the ADD-A-PHASE® ideal in most automated applications.
The autotransformer design of the ADD-A-PHASE® allows the capability to dictate the output voltage, therefore eliminating the need for costly external step-up or step-down transformers.
Through the years, variations of the standard ADD-A-PHASE® have been designed to suit specific applications.
