What is a phase converter and how does it work?

A phase converter converts single-phase power into three-phase power by generating the missing third phase. This allows you to run three-phase equipment (CNC machines, lathes, compressors, etc.) from a standard single-phase electrical service without the massive cost of utility three-phase installation.

Can I run multiple machines from one phase converter?

Yes — with a rotary or digital phase converter. Install a three-phase sub-panel fed by the converter and you can run as many machines as the converter's HP rating supports. Static converters are limited to a single motor.

How do I size a phase converter for my equipment?

Size your rotary phase converter to at least 1.5x your largest single motor, or to the total HP of all simultaneously running loads — whichever is greater. For hard-starting loads like compressors, go to 2x. Call us at 800-417-6568 for free sizing assistance.

What is the difference between rotary, static, and digital phase converters?

Rotary converters use an idler motor to generate balanced 3-phase power for multiple loads — best value for most shops. Static converters are cheaper but only power one motor at reduced capacity. Digital converters use electronics for near-perfect power quality — ideal for sensitive CNC equipment but cost 2-3x more.

How long does a rotary phase converter last?

A quality rotary phase converter lasts 20-30+ years with minimal maintenance. Phoenix Phase Converters backs every unit with a lifetime warranty — we expect our converters to outlast the equipment they power.

How much does a phase converter cost vs utility three-phase service?

A phase converter typically costs $1,500-$15,000 installed, while extending utility three-phase service runs $20,000-$150,000+. That's savings of 80-95%. Plus the converter is portable — take it with you if you relocate.
