    These rotary phase converters allow you to operate 3-phase machinery from a single-phase power source at 100% power and 95% efficiency. Each model operates up to twice its nameplate rating in mixed-motor load. For heavily-loaded or hard-start machinery, such as gearhead lathes, compressors, or dust collectors, choose a nameplate rating 3 times the HP of the most heavily loaded motor. See our individual 3-phase machine pages for specific phase converter recommendations. For application assistance, please call our technical support group at (570) 546-9663.
