40HP Rotary Phase Converter
Our 40HP rotary phase converter provides the voltage balance and true sinusoidal 3-phase AC output that many of today’s modern machines require. Our control panel has been engineered to exceed UL, CSA, & NEMA standards. We offer the easiest installation in the industry with custom enclosures with laser cut knockouts, terminal block connections, and no stress capacitor mountings.
40HP Control Panel Features:
- Push-Button ON/OFF Switch w/ Power Guard Protection (optional)
- 100% Power, Heavy Duty Performance
- Powder-Coated Steel NEMA 1 Enclosure
- Integrated protection in case of power interruption
- Removable sides for easy access to wiring
- Stress-free component mounts prevent leakage
- Oil-Filled capacitors with raised voltage ratings optimized for the demands of phase conversion.

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.
