Three-phase power from a single-phase source anywhere you need it. With twice the output starting capability of a rotary type converter, the Phase Perfect® digital phase converter uses modern solid-state electronics to create utility-quality three-phase power anywhere. Robust and durable, these phase converters are capable of powering any load. Over 20 years of development has led to a phase converter capable of running everything from hard-starting motors to equipment with delicate embedded electronics.
Phase Perfect® Simple

Based on the same phase conversion technology as its bigger brothers, but designed for home shop, light commercial, and single motor applications where the cost of the Enterprise and original Phase Perfect® are prohibitive.

The Phase Perfect® is also available in a compact, high-value, configuration where the customization options of the original are not required. These Enterprise models have the same modern digital phase conversion technology inside as the original.

Phase Perfect® Performance

The original Phase Perfect® digital phase converter supplies power to some of the most demanding industrial applications available under some of the most challenging conditions imaginable. Utility-quality three-phase power anywhere you need it.


Efficiency

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 eia.gov.

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.

Durability

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.

1. Simple model maintains voltage balance within 2%, just like the Phase Perfect®, under steady-state loads but may drop voltage on the generated leg briefly during motor startup.

2. Phase Simple will start and run multiple loads, as long as those loads do not add up to the peak starting capacity of the phase converter.

3. Certain Performance models (PT4150, 4175) will derate current output when operated above 40C.

Need 460V but have 230V?

In many situations 460V could result in significant cost savings, but too often those potential savings are eaten up by the need for a transformer. The voltage doubling Phase Perfect® turns single-phase 230V input into three-phase 460V output simply and reliably.
