The Light Duty series converter is designed for "one" single three-phase motor, which is easy starting and ran under a light load condition. This unit delivers 100% of the three phase motor horsepower, and it is comparable to our competitor's general duty and sometimes heavy duty rated units.

The Light duty Roto-Phase is designed for easy starting applications, where only one or two motors are operated. The Light-Duty Series delivers 100% of the three-phase motor horsepower rating for applications such as: centrifugal pumps, drill presses, saws, grinders, etc. For harder starting applications such as air compressors, hydraulic presses, oil well pumps: a hard start kit may be necessary. The Light-Duty Roto-Phase is designed to operate one motor equal to the largest motor rating, plus smaller motors to obtain the total horsepower capacity of the Roto-Phase. All models are rated in horsepower, with specific ratings of : "largest Motor HP" & "Total HP Capacity". The larges motor horsepower rating is in true horsepower, and is not intended to operate mis-rated motors or motor loads. For applications assistance consult our factory.
Model Notes:
* Paralleled Units
- O.D.P. or T.E.F.C. Design Available.
- Total horsepower capactiy may reach 1.5 to 2 times the larges motor HP catagory.
- Specify 230 VAC or 460 VAC.
- High Torque start kit availible, consult factory.
- Larger models available, consult factory.
- Refrigeration Equipment/Welders are sized by FLA/INPUT Amperes, consult factory.
- CAUTION: For foreign motor designs, 2-speed windings, instant reverse applications, consult factory.
