The World’s First
Digital Phase Converter
In 1999, Phase Technologies developed the world’s first digital phase converter, called the Phase Perfect® Digital Phase Converter — the first major advancement of phase conversion technology in decades.
The company expanded into variable frequency drives (VFDs) for irrigation, water pumping, HVAC and oil & gas industries.
Specializing in VFDs with Active Front End technology, Phase Technologies produces low-harmonic, fully regenerative, phase-converting VFD’s that comply with IEEE 519 — the international standard for allowable harmonic levels on utility mains.
