Why Buy From Us
Smart-Boost SB-15 Digital Rotary Phase Converter
The Smart-Boost SB-15 is an industrial-grade, solid-state digital rotary phase converter built for hard-starting three-phase equipment that places extreme demand on power during startup. Using Smart-Boost digital control technology, it delivers up to 600 percent additional current under heavy load, giving demanding motors the extra push they need to start cleanly and reliably.
This converter is designed for operators who already know standard rotary phase converters are not enough. If your equipment starts inconsistently, struggles under load, or causes repeated startup issues, the SB-15 is built to solve that problem directly.
Built for Industrial Hard-Starting Loads
The SB-15 is well suited for larger hard-starting air compressors, submersible pumps, flywheel-driven machinery, and gearhead lathes. These machines often require significantly higher current at startup than they do during normal operation, which is where many conventional converters fall short.
Smart-Boost technology responds dynamically to motor demand, delivering extra current only when it is needed. This allows difficult equipment to start reliably without overstressing the electrical system or the converter itself.
Smart-Boost Digital Control Technology
At the heart of the SB-15 is a solid-state digital control system capable of delivering a 600 percent current boost during heavy startup conditions. The controller actively manages power at the most critical moment, when motors are under maximum load.
This digital approach improves startup reliability while maintaining cleaner electrical behavior, making it suitable for industrial environments running high-value or sensitive equipment.
Smooth Starts and Efficient Power Delivery
Soft-start functionality helps reduce mechanical and electrical shock during startup. Motors ramp up smoothly instead of pulling aggressively, which helps extend the life of both the equipment and the converter.
The low-impedance, high-efficiency design supports effective power transfer, resulting in stronger motor response and more predictable operation under load.
Integrated Controls and Built-In Protection
The Smart-Boost SB-15 includes an integrated control panel with a built-in motor starter and solid-state relay. Startup and operation are handled automatically, keeping the system straightforward to operate even in demanding industrial settings.
All components are housed in a NEMA 1 indoor-rated enclosure, intended for clean, dry environments where protection and accessibility are both important.
Industrial Components Built for Long-Term Operation
At the center of the system is an idler-generator motor from ABB Baldor, widely trusted in industrial applications for durability and long service life. Self-healing, oil-filled motor start and run capacitors support consistent performance over time, even under repeated heavy starts.
Combined with solid-state digital control, these components make the SB-15 a long-term power solution rather than a temporary fix.
