North America SP-5 Smart-Phase Digital Rotary Phase Converter

SP-5 Single Phase to Three Phase Rotary Phase Converter

The SP-5 is a compact single-phase to three-phase rotary phase converter designed for lighter-duty applications where reliable three-phase power is needed without oversizing the system. It’s built for small shops, maintenance spaces, and individual machines that require dependable three-phase operation from a standard single-phase electrical supply.

If you’re running a single three-phase motor and want a simple, efficient way to power it without upgrading your electrical service, the SP-5 is designed to do exactly that.

Designed for Single-Motor Applications

The SP-5 supports a single motor start horsepower of up to 3 HP, making it a good fit for smaller machines such as lathes, mills, drill presses, pumps, and other light industrial or workshop equipment.

With a maximum capacity of 10 amps, this converter is intended for controlled, predictable loads rather than heavy industrial demand. It’s a practical solution when you need three-phase power for one machine and don’t want unnecessary complexity.

Efficient Power with Low Operating Cost

One of the advantages of the SP-5 is its low idle power usage. When running without load, it consumes approximately $0.04 per hour, helping keep operating costs predictable and manageable in small shop environments.

This makes it well suited for applications where the converter may remain powered throughout the day but only see intermittent machine use.

Straightforward Electrical Requirements

The SP-5 is designed to operate on a minimum 20-amp single-phase circuit, keeping installation requirements simple for most residential or light commercial settings. Its compact footprint and manageable weight make it easier to position in smaller spaces compared to larger rotary phase converters.

At approximately 75 pounds, it can be installed without specialized lifting equipment in most cases.

Built for Practical, Everyday Use

The SP-5 focuses on simplicity and reliability. It’s intended for users who want a straightforward phase conversion solution that works consistently without overengineering or unnecessary features.

This is a sensible choice for smaller operations that need three-phase power without stepping into larger, more complex systems.
