Type 2D-1 ROTO-CON® Rotary Phase Converters

cUL - U.S. Listed

Description

The ROTO-CON rotary converter provides smooth, reliable 3-phase power from single-phase lines. ROTO-CON Type 2D-1 is designed for applications with a single high starting torque motor or resistive loads with tighter voltage tolerances.

These models are sized to the largest three-phase motor (based on FLA rating) or total motor horsepower to be operated at one time. Some applications may require ROTO-CON to be oversized for correct operation. For non-motor applications, supply the FLA rating of the equipment and any voltage requirements.
