Ronk Add-A-Phase Type K-Duo Phase Converter

The Ronk Add-A-Phase Type K-Duo Phase Converter  is a static phase converter designed for use with two or more motors, or to provide redundancy of a single motor in critical applications.

AVAILABLE STANDARD MODELS

• 2K: 1PH 240V to 3PH 240V; Converter HP Options of 3-80 hp.
• 2K-8: 1PH 240V to 3PH 208V; Converter HP Options of 3-50 hp.
• 3K: 1PH 240V to 3PH 480V; Converter HP Options of 3-80 hp.
• 4K: 1PH 480V to 3PH 480V; Converter HP Options of 3-80 hp.

AVAILABLE OPTIONS

• K-SUB: Operate 2 pump motors with higher than standard FLA rating.
• K-AC: Operate 2 air conditioning compressor motors.
• K-SP: Operate 2 motors with different HP ratings.
• L: Operate 3 motors (trio).
• Q: Operate 4 motors (quad).
• N: Operate 5 motors (penta).

TYPICAL APPLICATIONS

• Compressors: air conditioning and associated motors.
• General applications.
• Sewage lift stations and booster pumps.

FEATURES

• Operates multiple motors to their full load rating, plus normal overload.
• Limits inrush current when the motors are starting, a critical factor on most single phase lines.
• Can be adjusted to provide balanced currents to multiple motors operating at a constant horsepower load.
• Can be designed to handle three to five 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.
• Can be used to offer redundancy in critical applications – any failure in one of the convertors leaves the others to operate the system until repairs can be made.
• Housed in a NEMA 3R outdoor enclosure.
• UL Listed.
• Three-Year Limited Warranty.
