Phase Perfect®

Utility quality three-phase power anywhere you need it.

Three-phase power from a single-phase source anywhere you need it. Phase Perfect® digital phase converter uses modern solid-state electronics to create utility-quality three-phase power anywhere. Over 20 years of development has resulted in a robust and durable phase converter capable of powering any load, from hard-starting motors to equipment with delicate embedded electronics.

Power Quality

Hard-starting motors demand maximum output along with over-current protection. Delicate embedded electronics, which are getting more common by the day, demand perfectly balanced voltage always, no matter what the demands are on the rest of the system.

No other phase conversion technology can supply the brute force required to start the most demanding loads while protecting everything down to the smallest integrated circuit from damage. The Phase Perfect® uses modern microprocessor-controlled electronics to continuously adapt to changing conditions.

Don't subject your expensive equipment to improper phase timing and voltage imbalance inherent in dated phase conversion technologies. Get utility-quality power with Phase Perfect®.

Maintains phase-to-phase voltage balance within 2%

Electronic power factor correction produces near unity power factor

Sinusoidal input current with very low harmonic content

Output LC filter blocks digital switching-generated noise producing sinusoidal output


An embedded microprocessor constantly ramps up or down based on the needs of the attached equipment. Full power is there when you need it without any wasted energy when you don’t. High efficiency under load and extremely low power utilization when not loaded add up to big cost savings compared to other phase conversion technologies.

The Phase Perfect® will also return power to your single-phase source when any three-phase load is in generating mode. Returning this power and making your utility meter run backwards is a much more efficient solution than wasting any excess power by heating a resistor.


Phase Perfect®’s have been powering equipment outdoors in the harshest of conditions for over 20 years. The brownouts, outages, and surges in remote areas that see frequent blizzards, lightning storms, and other severe weather has helped our engineers harden the Phase Perfect® into a highly reliable product.

The electronics have been made extremely robust, including the addition of costly film type line filter capacitors and custom inductors. The chassis has an available rain hat that brings it to a NEMA 3R outdoor rating. The onboard software has also been continually upgraded with advanced monitoring and protections to help keep the Phase Perfect® and your expensive equipment safe.


A huge number of applications and equipment once considered "industrial" require three-phase power. This equipment is increasingly finding use on farms and ranches, in home shops, or other locations where utility-provided 3-phase isn't readily available.

Modern electronic safety features are showing up everywhere, and internet-connected equipment is becoming commonplace. Equipment with embedded electronics is highly sensitive to power quality, and some methods of phase conversion will damage these electronics. A Phase Perfect® will ensure any equipment runs just like it was connected to three-phase from the power company.

Common uses for the Phase Perfect®: Elevators, HVAC, Wineries, Irrigation, Woodworking, Machine Shops, CNC Equipment, Polishing & Grinding

Voltage Doubling

If your application requires 460V power the Phase Perfect® Enterprise becomes an even more economical and streamlined solution. Models are available that internally increase the voltage from a 230V supply without requiring a transformer.

Learn about voltage doubling


  1. Mount with supplied mounting kit.
  2. Connect two wires in, three wires out.
  3. Ensure the Phase Perfect® is well grounded.

Installation of a Phase Perfect® is virtually “plug-and-play”. Equipment or a three-phase load center can be connected to the output just like they would be hooked up to utility three-phase.
