ADD-A-PHASE® Power Converter Type K-Duo
Features:
- Balanced Motor Currents - Can be adjusted to provide balanced current to multiple motors operating at a constant horsepower. Limits inrush current when the motors are starting, a critical factor on most single phase lines.
- Options - Special 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.
- Redundancy in Critical Applications – Any failure in one of the convertors leaves the others to operate the system until repairs can be made.
Applications:
- Air Conditioning - Compressors
- Wastewater lift stations/ booster pumps
- Multiple motors
