AI – Industrial Phase Converter

AI Industrial Grade Rotary Phase Converter – The AI Industrial was designed specifically for the demands of industrial and agricultural applications. Our AI Industrial digital phase converter is designed with a Type 3R enclosure for ultimate protection.

The AI series is designed to be in extremely dirty environments or even installed outside. The AI-Industrial line is made as a full NEMA-3R enclosure with solar reflective paint. It also features a washable air filter to filter out any dust and debris from circulating through the phase converter.

Since the AI phase converter is in an all-in-one, the NEMA-3R enclosure makes for a simpler installation. You just have to run your single phase in and your three-phase out!

AI Industrial can save you thousands of dollars a year over utility and diesel generated power sources.

Lead times may exist. Please call us for further details.
