North America Pro-Line PL-20 Rotary Phase Converter

Pro-Line PL-20 HP Single Phase to Three Phase Rotary Phase Converter

The Pro-Line PL-20 HP is a professional-series rotary phase converter built for larger three-phase equipment that needs real, dependable power. Rated at 20 horsepower, CNC-rated, and digitally started, it’s designed to take standard single-phase power and deliver full running current to three-phase machines without compromises.

If you’re running big motors, heavier CNC equipment, or multiple three-phase machines and utility three-phase power isn’t an option, the PL-20 HP gives you a proper alternative. It’s made for operations where underpowered solutions are no longer acceptable.

Built for Heavy Equipment and High Demand

The PL-20 HP is intended for demanding shop environments where machines run hard and downtime costs money. It’s commonly used for larger CNC machines, industrial compressors, pumps, and other high-horsepower three-phase equipment that needs stable power under load.

This is the size converter people move to when smaller units are no longer enough and reliability becomes non-negotiable. It allows you to run serious equipment in facilities with only single-phase service, without reworking your entire electrical infrastructure.

Smooth Starts, Stable Power

With a digitally controlled soft-start system, the PL-20 HP reduces startup stress on both the converter and connected machines. Motors ramp up smoothly instead of pulling aggressively at startup, which helps protect equipment and keeps operation more predictable.

Once running, the converter provides balanced, consistent three-phase power so machines operate smoothly and as intended. The focus here is simple, steady performance that doesn’t get in the way of work.

Integrated Controls and Built-In Protection

The PL-20 HP includes an integrated control panel with a built-in motor starter and digitally protected start circuit. Startup and operation are handled automatically, keeping things straightforward and reducing the need for additional external components.

Everything is housed in a NEMA 1 indoor-rated enclosure, designed for clean, dry environments where the system can be accessed easily for service or inspection.

Industrial Components Designed for Long-Term Use

At the core of the system is an idler and generator motor from ABB Baldor, widely used in industrial environments where durability and long service life matter. The Open Drip Proof motor design is indoor-rated and supports reliable cooling during normal operation.

This is not a short-term workaround. It’s a long-term power solution built to stay in place and perform year after year.
