SP-30 Single Phase to Three Phase Rotary Phase Converter

The SP-30 is a high-capacity single-phase to three-phase rotary phase converter designed for serious workshop and light industrial environments running large single-motor equipment. It delivers stable, dependable three-phase power from a standard single-phase electrical supply, without stepping into full industrial rotary systems.

If you’re operating a large three-phase machine in the 15 to 20 HP range and need strong starting performance with consistent operation under load, the SP-30 is built to handle that level of demand.

Designed for Large Single-Motor Loads

The SP-30 supports a single motor start horsepower of up to 20 HP, making it suitable for large lathes, mills, compressors, pumps, and other high-demand shop equipment that require substantial startup current.

With a maximum capacity of 56 amps, it provides the electrical headroom needed for smooth starts and stable operation, while remaining focused on single-machine applications rather than multi-load industrial systems.

Efficient Power at Higher Capacity

As capacity increases, efficiency still matters. The SP-30 has an idle power usage of approximately $0.21 per hour, helping keep operating costs predictable in shops where the converter may remain powered for long periods.

This balance of power and efficiency makes it a practical solution for operations that need serious capability without unnecessary waste.

Electrical Requirements That Match the Workload

The SP-30 is designed to operate on a minimum 70-amp single-phase circuit, typical for well-equipped workshops and light industrial facilities running larger machinery.

At approximately 317 pounds, it reflects the robust construction and capacity required to support higher-horsepower equipment, making it best suited for permanent installation in a dedicated shop environment.

Built for Shops Running Big Equipment

The SP-30 is intended for users who have clearly moved beyond mid-range converters and now require strong starting torque, electrical stability, and dependable performance day in and day out.

It focuses on reliability and straightforward operation, without unnecessary complexity or overengineering.
