SP-15 Single Phase to Three Phase Rotary Phase Converter

The SP-15 is a higher-capacity single-phase to three-phase rotary phase converter designed for workshops and small industrial spaces running larger single-motor equipment. It delivers dependable three-phase power from a standard single-phase electrical supply, without pushing you into oversized industrial systems.

If you’re operating a three-phase machine in the 7.5 to 10 HP range and want stable, predictable performance without upgrading your electrical service, the SP-15 is built for that exact use case.

Designed for Higher Horsepower Single-Motor Loads

The SP-15 supports a single motor start horsepower of up to 10 HP, making it a strong fit for larger lathes, mills, compressors, pumps, and other shop or light industrial equipment that require more starting torque and sustained power.

With a maximum capacity of 29 amps, it provides solid headroom for smooth operation under load while remaining focused on single-machine applications rather than multi-load environments.

Efficient Operation for Daily Use

As capacity increases, efficiency still matters. The SP-15 maintains reasonable idle power usage at approximately $0.11 per hour, making it practical for shops where the converter may stay powered during the workday while machines cycle on and off.

This balance of capability and efficiency helps keep operating costs predictable as your equipment requirements grow.

Clear Electrical Requirements

The SP-15 is designed to operate on a minimum 40-amp single-phase circuit, a common setup in light commercial and well-equipped workshop environments.

At approximately 187 pounds, it remains manageable for installation while offering a noticeable step up in capability from smaller SP-series models.

Built for Real Shop Progression

The SP-15 is for users who have moved past entry-level converters and now need something with real starting power and stability. It focuses on reliability and straightforward operation, without unnecessary complexity or features you won’t use.

It’s a natural upgrade when smaller converters are no longer enough, but full industrial systems would be excessive.
