ARCO HD-2 PHASE CONVERTER HD

Roto-Phase II – Heavy Duty

Converts single phase power into three phase power!

This unit has greater capacity than any rotary converter made. A substantial increase of iron, copper and matched capacitance provides for harder starting motors to operate as well as handling more large motors and more total horsepower. It is the Heavy-Duty of the Roto-Phase line. Where there are two or more motors of equal rating, smaller motors, Roto-Phase II should be used. Total capacity could reach four times the largest motor rating.

FEATURES:

• 230V Standard.
• Instant reversing cycles efficiently performed.
• Multi-speed motors operate equally well.
• Motors may be either Wye or Delta connected.
• No motor modification is required.
• Multiple motors operate from one unit.
• Numerous successful applications such as welders, computers, CNC, etc.
• Specific models for CNC also available.

HOW TO SELECT:
Match the largest motor to be operated (in true HP) with the column entitled "Largest Motor". Next match the column entitled "Horsepower". Choose the larger of the two models.
1. Standard Duty Models are designed to handle one (1) 3-phase motor at the Largest Motor indicated. Remainder of the load motors should be of lesser HP. Motors may be 3,600, 1,800, or 1,200 RPM. RPMs of 900 and lower refer to Roto-Phase II.
2. Many submersible pump motors have full load amperages greater than standard motors. Consult Factory.
3. Extremely hard starting applications such as hoists, air conditioners, heat pumps, elevators, laundry extractors, etc., require Roto-Phase II. Consult Factory.
4. Some grain dryers require the motor(s) to run electrically overloaded; often as high as 30% overload. Consult Factory, giving name and model of grain dryer and HP of motors for recommendation as to size and type.
5. Resistance loads (resistance welders, EDM electric discharge machines etc.) should be sized by input load amperes. Consult Factory.
