North America SP-10 Smart-Phase Digital Rotary Phase Converter

SP-10 Single Phase to Three Phase Rotary Phase Converter

The SP-10 is a mid-capacity single-phase to three-phase rotary phase converter designed for shops and workspaces running slightly larger three-phase motors. It’s built for reliability and simplicity, giving you dependable three-phase power from a standard single-phase electrical supply without stepping into oversized industrial systems.

If you’re running a single three-phase machine in the 5 to 6 HP range and want stable performance without unnecessary complexity, the SP-10 is designed to fit that role cleanly.

Designed for Larger Single-Motor Applications

The SP-10 supports a single motor start horsepower of up to 6 HP, making it well suited for medium-size lathes, mills, compressors, pumps, and other shop equipment that need more starting power than entry-level converters can provide.

With a maximum capacity of 20 amps, it offers enough headroom for steady operation while remaining focused on controlled, single-machine use rather than multi-load industrial environments.

Efficient Operation with Predictable Power Use

Despite its increased capacity, the SP-10 remains efficient at idle. With an idle power usage of approximately $0.08 per hour, it’s practical for workshops where the converter may stay powered throughout the day while machines cycle on and off.

This balance of capability and efficiency makes it a sensible choice for growing shops that need reliable power without unnecessary operating cost.

Straightforward Electrical Requirements

The SP-10 is designed to operate on a minimum 30-amp single-phase circuit, which is commonly available in light commercial and larger residential workshop settings.

Weighing approximately 139 pounds, it remains manageable in terms of installation and placement, especially compared to larger industrial rotary phase converters.

Built for Practical, Everyday Shop Use

The SP-10 focuses on doing one job well, providing stable three-phase power for a single machine that needs a bit more starting torque and capacity. It’s a solid step up from smaller converters without pushing you into systems that are oversized for your actual workload.
