Digital Phase Converters

Digital Phase Converters

NAPCco’s digital phase converters convert single-phase power into clean, balanced three-phase power using high-speed, solid-state switching, with no rotating parts. An integrated microprocessor monitors the output and maintains phase-to-phase voltage balance within 2% under any load, making the digital range the right choice for CNC machines, VFD-controlled equipment, elevators, HVAC systems and other voltage-sensitive loads. Every unit is built in the USA.

How do you size a digital phase converter for your equipment?

Properly sizing a digital phase converter matters. Choose the right size, and you get years of trouble-free performance. There is no minimum load requirement, and you can never oversize, so if you are between two models, it is safe to move up; undersizing is what causes problems.

Enter your equipment type and horsepower in our sizing tool and we will recommend the right model and size. Buy online with confidence, or call us at 877-545-2926 and our engineers will size your application for free.

Talk to an application engineer for free

A digital phase converter needs to match the equipment it will run, and voltage-sensitive machines leave little room for error. Tell our application engineers what you are powering, and they will recommend the right model at no cost, backed by our sizing guarantee. If the size is wrong, we replace the unit and cover shipping both ways.
