Specifications
This 7.5HP Rotary Phase Converter changes input single phase power into three phase power, allowing shop equipment to operate at maximum efficiency. The proper size of a phase converter is determined by the largest load motor to start. Please call toll free 1-888-743-6832 for sizing assistance and/or our recommendation for your specific application. This 7.5HP unit will start and run:
-
Easy Loads up to 5HP:
Small Drills, Mills, Chop Saws, Wheel Balancers, etc. -
Medium Loads up to 4HP:
Auger, Meat Grinder, Radial Arm Saws, Drills, etc. -
Hard Loads up to 3HP:
Refrigeration Compressors, Ice Cream Machines, Lathes, Sanders, Mixers, etc. -
CNC Loads up to 3HP:
Milling Machine, Lathe, etc.
Sizing Help
Determine the load type of the application, and then consult the chart below. Please call us toll free at 1-888-743-6832 for sizing assistance and/or a professional recommendation.
- Easy - no flywheel, clutch, little resistance/inertia, 1-2 times full load current upon start-up
- Medium- machine inertia, medium resistance, 3-4 times full load current upon start-up
- Hard - flywheel, no clutch, starts against load, 5-6 times, or locked rotor current upon start-up
- Very Hard- elevator, hydraulic pump, equipment under continuous load etc
- Frequent Start- instant reversing, heavy running loads
- CNC - turning centers, PLC's, EDM, CNC machining
- Resistive - heaters, transformers, welders, power supplies etc.
