Add a phase converter

Single motor applications only. Cost-effective unit that operates constant horsepower loads more efficiently (approx. ) than other phase converters on the market. The Ronk POWRSOFT CONTROLLER is engineered to soft start Ronk Rotary Phase Converters.

By reducing the normal starting inrush on the single phase line by up to , larger rotary converters may be used on utility single phase lines for irrigation systems and other loads when three phase is not available.

Type AA is the ADD-A-PHASE static three- phase converter designed to handle the loads listed above.

Equipment whose loads vary more than can be efficiently run on this type unit.

Using Type AA on these loads is both effective and efficient especially under light load conditions.

Just add your own 230v 25hp idler motor. Type SAC is an ideal ADD-A-PHASE static three- phase converter for most air conditioning applications. Its high efficiency, high starting torque, ease of use in automated systems and the ability to provide balanced currents to motors allow it to operate three-phase compressor (and fan) motors at full rated load.

Autotransformer-capacitor type static converters are generally recommended for constant load applications, like most fans or pumps, with one or two motors. Because of the variations in applications, the converter required may vary from the units shown in this general guide.

All converter quotes must come from the factory to ensure proper sizing and application. Since phase converters generate one leg that must . The best way to size the incoming single-phase service is to add the full-load running amps of all the 3-phase loads that will operate simultaneously. The National Electric Code requires the service to be at least 2 of the total 3- phase load amps.

Do utility companies approve of phase converters ? For 2-speed motors, add horsepower together of two speeds and size from that horsepower converter.

General Sizing Rules for Rotary Phase Converters. For Easy Loads – Should be at least one size larger than load motor.
