Phase Perfect® enterprise
The Phase Perfect® Enterprise is a compact, high-value configuration with a voltage doubling option for 460V output. These Enterprise models have the same modern digital phase conversion technology inside as the original.
Shop NowPhase Perfect® simple
The PTS model, built on the same phase conversion technology as the PT and PTE but in a more compact design, is ideal for home shops, light commercial use, and single-motor applications where the cost of the Enterprise and original Phase Perfect® models may be prohibitive.
Shop NowThree-phase power from a single-phase source, anywhere you need it. Phase Technologies has developed phase converters with twice the starting capability of a rotary phase converter with 98.7% efficiency and 2% voltage balance, all in a smaller footprint than a rotary. Phase Perfect® digital phase converters use 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.
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.

Efficiency
Phase Technologies' digital phase converters offer significantly higher efficiency compared to traditional rotary phase converters. Unlike our competitors, which rely on mechanical rotation and can suffer from energy losses, noise, and maintenance issues, digital phase converters use solid-state electronics to deliver clean, balanced three-phase power with minimal losses. This results in 98.7% efficiency, reduced heat generation, and improved performance and longevity for sensitive equipment.

Voltage Balance
Phase Technologies' digital phase converters provide superior voltage balance compared to other three-phase producing equipment, within 2% to be exact. This ensures more stable and reliable power for three-phase equipment. Rotary converters often produce unbalanced voltages, which can lead to inefficient motor performance, overheating, and potential equipment damage.
Our digital converters use advanced solid-state electronics to actively regulate voltage, maintaining near-perfect phase balance. This precise voltage control enhances motor efficiency, extends equipment lifespan, and reduces energy waste.
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.
Motor Starting Ability
Phase converters have wildly different characteristics on their ability to start and run motor loads.

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