Ronk Type 4K-SUB Duo Add-A-Phase Power Converter for 3-60HP, 480V Motor Features:
The K-DUO ADD-A-PHASE will operate multiple motors to their full load rating, plus normal overload. It also limits in-rush current when the motors are starting, a critical factor on most single phase lines. The K-DUO ADD-A-PHASE can be adjusted to provide balanced currents to multiple motors operating at a constant horsepower load. Other units can be designed to handle 3 to 5 motors either separately or simultaneously. Variations are available to handle motors with higher than standard FLA ratings, motors with different HP ratings, and other applications. This family of converters offers redundancy in critical applications - any failures in one of one of the convertors leave the other(s) to operate the system until repairs can be made. The Type 4K-SUB models convert a single phase 480 Volt to a three phase 480 Volt.
