Phase Perfect® is also available in compact, high-value Enterprise models with available voltage-doubling 480V options.

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

NEMA 1 all steel enclosure


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.

The cost in cents per kilowatt/hour your utility charges you for electricity usage. You can estimate costs for your region by looking at the Average Price Chart on

Weeks per Year
Days per Week

Number of weeks per year and days per week you anticipate needing 3 Phase power available. For example: a business with typical operating hours might be 50 weeks per year and 5 days per week, while an elevator installation would require 52 weeks per year and 7 days per week.

Hours Per Day

The number of hours per day you anticipate not drawing a significant 3 Phase load. For example: a typical business might not draw a significant load right away in the morning, during breaks, or over the lunch hour, while an elevator might be idle 20 or more hours per day.

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 is available with a NEMA 3R outdoor rating, so you can mount it anywhere without worry. 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® Enterprise 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.



Surge Protection

Strikesorb provides class-leading multiple hit protection ensuring continuous protection of your critical equipment.

MCCB & Service Rated Disconnect

Quickly and easily disconnect the phase converter from power any time maintenance or any other need arises.

On/Off Switch

The optional on/off switch will completely turn off power to any connected devices, both on the two pass-through legs as well as the generated leg.

Extended Warranty

Although durable and robust in design, a little extra peace of mind never hurts. Phase Technologies is happy to offer an extended warranty for all of those applications that demand a bit extra.

Motor Starting Ability

Phase converters have wildly different characteristics on their ability to start and run motor loads.
