The Ronk Rotoverter Type D Phase Converter is a rotary phase converter designed for multiple loads of varying horsepower ratings when the largest motor hp is more than half of the total load hp. Can also be used for non-motor loads. Please call for assistance.
AVAILABLE STANDARD MODELS
- 2D: 1PH 240V to 3PH 240V; Converter Size Options of 1.4 – 42VA.
- 4D: 1PH 480V to 3PH 480V; Converter Size Options of 1.4 – 42kVA.
TYPICAL APPLICATIONS
- CNC equipment.
- Compressors: refrigeration, air conditioning.
- Pumps: centrifugal, heating systems, turbine.
- Lift stations.
- Fertilizer plants.
- Grain dryers.
- Multiple small motors.
FEATURES
- Consists of a rotary transformer and one capacitor panel.
- Patented Tap adjustments give you control over all three phases for balancing currents.
- Open drip-proof (ODP) Rotary Base.
- UL Listed.
- Three-Year Limited Warranty.
AVAILABLE OPTIONS
- C-AS: Automatic Start. Automatic start units are supplied with a contactor and associated controls that allow the unit to be integrated with equipment that may cycle automatically from control circuitry containing timers, level or pressure sensors, etc. This allows the rotary transformer to come to speed before the load is energized, as required by Article 455-21 of the NEC.
- P-CS: Contactor Start.
- P-DS: Delayed Stop.
