The Standard Duty Roto-Phase is designed to operate multiple motors simultaneously with ONE three-phase motor equal to the largest motor rating of the rotary phase converter, and the remaining three-phase motor loads are smaller in horsepower rating for a combined operated load equal or less than the Recommended Horsepower Capacity of the phase converter. The Standard Duty Series design is the industry leader for its quality, performance, and dependability in providing economical three-phase power. The Roto-Phase I units are built from a larger rotary frame design than most converter manufacturers; therefore delivering a superior three-phase converter system. All models are rated in horsepower rather than KVA, and they list the specific ratings of the rotary phase converter (LARGEST MOTOR HP & TOTAL HP CAPACITY). The largest motor horsepower rating is in true horsepower, and it is not intended to operate mis-rated motor or motor loads. If the largest motor horsepower rating is starting or running in continuous overload or has a low power factor rating, then the next larger Roto-Phase I Standard Duty or Roto-Phase II Heavy Duty may be required. When two motors match the largest motor rating of the phase converter, a larger Roto-Phase converter is usually required…CONSULT FACTORY.
