Smart-Boost™ Digital Rotary Phase Converters
Some motors are just harder to start. Air compressors, irrigation pumps, fans, blowers, and large flywheel loads demand a surge of power at startup that a standard rotary phase converter may struggle to deliver. The Smart-Boost was built specifically for those situations.
The Smart-Boost™ converts single-phase power into three-phase power and adds a digital boost controller that delivers 300% more starting current to hard-starting motors every time they start, not just on the initial startup. If your equipment trips breakers, struggles to start under load, or needs flying restarts, the Smart-Boost is the right converter for the job.
Models are available from 3 HP to 60 HP. Built in the USA and backed by a 10-year parts/lifetime labor warranty.
Best Applications: Air compressors, irrigation pumps, lift station pumps, fans, blowers, grain dryers, large flywheel loads, and any hard-starting or high-inertia motor load.

Complete Details of Features
Smart-Boost™ Digital Controller
At the core of every Smart-Boost is a solid-state digital controller that re-engages the start capacitors at zero-degree crossing. This delivers a powerful, controlled surge of starting current without damaging the capacitors or the connected equipment.
- Electronic solid-state switching, no mechanical contacts to wear out
- 120-degree pure sine wave output for clean, stable three-phase power
- Zero-degree capacitor switching for maximum starting torque
- Self-protected SCR power semiconductors guard against voltage spikes and overloads
- Voltage differential technology monitors and adjusts output in real time
300% Motor Starting Boost Current
This is the feature that sets the Smart-Boost apart. When a hard-starting motor calls for power, the Smart-Boost surges 300% more current to get it moving. This happens every time an external motor starts, not just at initial converter startup.
- 300% starting boost current delivered on every external motor start
- Flying restarts supported, the converter does not need to fully cycle down between starts
- Capacitor voltage synchronization on reconnect for smooth, reliable restarts
- Ideal for high-inertia loads like compressors, pumps, fans, and flywheel equipment
Built-In Motor Starter
Every rotary phase converter needs a starting mechanism. The Smart-Boost includes a fully integrated magnetic motor starter as a standard feature, saving you the cost of a separate unit.
- Integrated magnetic motor starter included as standard
- Start/stop switch mounted on the front of the panel for easy access
- Power ON indicator light visible from across the room confirms the unit is running
- No separate starter required, saving time and money on installation
Total Power Shutoff Protection
In the event of a power outage or power loss, the Smart-Boost activates complete three-phase power loss protection by shutting down all three legs of power simultaneously. This protects your motors and equipment from single phasing when power returns.
- Shuts down all three legs of power simultaneously during a power loss or brownout
- Protects motors and equipment from single phasing when utility power resumes
- Competing brands often only cut the generated leg, leaving your equipment at risk
Easy Installation
The Smart-Boost is designed to go up quickly and wire up cleanly.
- Removable sub-panel design keeps the enclosure light and easy to mount
- Oversized power distribution blocks are clearly marked and easy to access
- Large wiring compartment gives you plenty of room to work
- Knockouts on the bottom and right sides accommodate most conduit routing
Important Extras
Details that add up to a converter that lasts.
- Oil and epoxy-filled capacitors with no limit on the number of motor startups; can stay energized for extended periods without degrading
- High-current protective coils guard against voltage surges and fast transient short circuits
- Large bleed resistors extend capacitor life
- Made in the USA by a UL 508A certified panel builder in Wisconsin
