North America Pro-Line PL-7 Rotary Phase Converter

Pro-Line PL-7 HP Single Phase to Three Phase Rotary Phase Converter

The Pro-Line PL-7 HP is part of the Professional Series rotary phase converters, built to convert standard single-phase power into usable three-phase electricity for real-world equipment. It is CNC-rated, digitally started, and designed to supply full running current to three-phase machines without cutting corners.

If you’re running serious equipment but don’t have access to utility three-phase power, this unit solves that problem cleanly. It lets you run your machines the way they were meant to run, using the power you already have.

Made for Shops That Actually Use Their Machines

The PL-7 HP is sized for heavier shop equipment and continuous use. It’s a strong fit for CNC machines, mills, lathes, compressors, and other three-phase tools that need stable power, not guesswork.

This is especially useful in workshops, leased units, rural buildings, or agricultural setups where upgrading to three-phase utility power either isn’t possible or just doesn’t make financial sense. Instead of changing your building, you power your equipment properly.

Smooth Starts and Steady Power

This rotary phase converter uses a digitally controlled soft-start system, which means less stress when machines start up and more consistent performance once they’re running. Motors spin up smoothly, power stays balanced, and equipment runs more predictably under load.

In simple terms, it helps your machines run cleaner and reduces unnecessary wear caused by unstable power.

Simple Controls, Built-In Protection

The PL-7 HP comes with an integrated control panel and built-in motor starter, so everything works together out of the box. The digitally protected start circuit manages startup automatically and helps protect the system during operation.

The NEMA 1 indoor-rated enclosure is intended for clean, dry environments and keeps internal components protected while still being easy to access for service or inspection.

Built to Last, Not to Be Replaced

At the heart of the system is an idler and generator motor from ABB Baldor, a name trusted in industrial motor applications for durability and long service life. The Open Drip Proof motor design is indoor-rated and supports reliable cooling during normal shop operation.

This converter is built for long-term ownership. It’s the kind of equipment you install once and expect to keep using year after year.
