    Where waterproofing, guarding against salt water corrosion, or any other special requirement is needed, Phase-A-Matic will provide a quote. Custom orders require a minimum of 8-9 weeks lead time.

  • "KW" Series Rotary Phase Converter

    Designed for world-wide use where the voltage input is 400-480VAC, 50Hz or 60Hz

    Runs 3-Phase Equipment at FULL POWER from Single-Phase Power


    The Rotary Converter is designed to supply full running current to a three-phase motor, normally providing it with full running torque. However, most motors will draw five times their running current during start-up. When sized KW for KW the Rotary Converter cannot deliver the full (5 times) starting current to the motor and therefore cannot provide full starting torque. You must always use a larger KW rated Rotary Converter than the KW rating of the motor. Please refer to the “KW” Rotary Converter Application Notes page, or form RTNKW.pdf.
