Three-phase for the machine shop
Mills, lathes, surface grinders, large air compressors and other industrial equipment commonly found in small machine shops require three-phase power.
More and more machine shops are being started in rural and other non-industrial areas where three-phase power is not available, or is prohibitively expensive. The Phase Perfect® was specifically designed to address this need and provide shops with a reliable, economical three-phase converter. Just feed single-phase into the unit and get utility-quality three-phase back out.
CNC equipment is becoming more and more common, and modern non-CNC equipment often has convenience or safety features controlled by a microprocessor or other delicate electronics. These electronic controls require extremely well balanced power or they can be damaged. The Phase Perfect® continually adjusts to ensure your machines have a healthy diet of utility-quality three-phase power.
In many cases, machine shop equipment requires 208V delta configured three-phase power. A Phase Perfect® is easily paired with relatively inexpensive buck/boost transformers to lower voltage to 208V from 240V if required.
Most importantly,
WE SAVE YOU MONEY.
No costly utility upgrades, just efficient, reliable power for your system.
