RONK's Add-A-Phase Type K-Duo

ADD-A-PHASE Power Converter Type K-Duo

Part Number:
AAP(x)K(xxx)
Item Code:
AAP(x)K(xxx)

The Add-A-Phase® Type K-Duo is a high-performance static phase converter designed to efficiently generate three phase power from a single phase source. Engineered for applications requiring balanced voltage and reliable motor performance, this converter is ideal for operating multiple three phase motors simultaneously, making it a preferred choice for industrial and agricultural operations.

The Type K-Duo features a dual-output design, allowing it to power two separate three phase motors while maintaining optimal voltage balance. This configuration enhances operational flexibility and efficiency, ensuring smooth performance across various motor-driven applications such as pumps, conveyors, compressors, and processing equipment.

Built with an advanced autotransformer-capacitor system, the Add-A-Phase Type K-Duo provides consistent and efficient power conversion, reducing electrical stress on motors and improving longevity. Unlike rotary phase converters, this static unit operates with minimal maintenance and no moving parts, offering a cost-effective and dependable solution where three phase utility service is not available.

Encased in a durable, weather-resistant enclosure, the Type K-Duo is designed to withstand harsh environmental conditions, making it suitable for both indoor and outdoor installations. The straightforward wiring and compact design allow for easy integration into existing electrical systems, reducing setup time and installation costs.

Ideal for demanding applications that require simultaneous operation of multiple motors, the Add-A-Phase Type K-Duo delivers reliable three phase power with efficiency and stability, ensuring optimal performance for a wide range of industrial and agricultural equipment.

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
