The Phase Perfect Residential Pro turns your single-phase 230V into true three-phase 230V—98.7% efficient with voltage balanced within 2%, as good as the power you'd get from the electric company. Your motors run at full power, stay cool, and last longer. Other converters can't say that. A rotary wastes electricity on standby whether you're working or not. A static only gives your motors half their power and runs them hot until something breaks.
The Residential Pro uses 80% less standby power than a rotary, runs 82% quieter, and takes up less space. No parts to wear out, no adjustments to make. Built-in digital monitoring keeps your equipment safe. Handles 3-7.5 HP loads—grinders, lathes, mills, compressors, dust collectors, and more. Starts hard loads and runs multiple machines at once. Easy to install, compact indoor enclosure.
Stop wasting money on lost power and burned-out motors. The Phase Perfect Residential Pro gives you what other converters can't: all the power you're paying for, every time.

Unlike a rotary converter, there's no need to double HP
At Phase Technologies, every phase converter and VFD is built at our Rapid City, South Dakota headquarters. Each unit is assembled, fully tested, and treated as a custom build. We manufacture key components in-house, keeping our supply chain short and US-based for quality, reliability, and speed.
With the industry’s fastest lead times, Phase Technologies delivers exactly what customers need—power electronics proudly made in the USA.
The Phase Perfect® Residential Pro digital phase converter uses the same proven technology as our Phase Perfect® Performance and Enterprise converters but is specifically designed for smaller motor loads found in home garages or small shops.
