Smart-Boost SB-30 Digital Rotary Phase Converter

The Smart-Boost SB-30 is a high-capacity digital rotary phase converter engineered for large three-phase equipment that places extreme demand on power during startup. Using Smart-Boost digital control technology, it can surge up to 600 percent additional current at startup, giving heavy motors the support they need to start cleanly, reliably, and without repeated attempts.

This unit is designed for operations that have already discovered the limits of standard rotary phase converters. If motors downstream hesitate, stall, or struggle to overcome startup load, the SB-30 is built specifically to remove that problem.

Built for Large, Hard-Starting Industrial Motors

The SB-30 is suited for large air compressors, submersible pumps, flywheel-driven machinery, gearhead lathes, and other high-inertia three-phase equipment. These machines often draw several times their normal running current during startup, which is exactly where conventional converters fall short.

Smart-Boost technology responds dynamically to these conditions, delivering extra current only at the moment it is required. This allows demanding equipment to start reliably without overstressing the electrical system or the converter itself.

How Smart-Boost Digital Control Supports Startup

At the core of the SB-30 is a Smart-Boost digital controller that uses solid-state relays to re-energize start capacitors at zero-degree crossing on the sine wave. This precise timing allows the system to inject additional current during startup while minimizing electrical noise and harmonic distortion.

In practical terms, this results in stronger motor starts, smoother transitions to running speed, and cleaner power behavior in demanding industrial environments.

Smooth Starts and Efficient Power Transfer

Soft-start functionality helps reduce mechanical and electrical shock during startup. Motors ramp up smoothly instead of pulling abruptly, which helps extend the life of both the connected equipment and the phase converter.

The low-impedance, high-efficiency design supports effective power transfer, resulting in better motor response and more predictable performance under heavy load.

Integrated Controls and Built-In Protection

The Smart-Boost SB-30 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 use even in industrial environments with complex machinery.

All components are housed in a NEMA 1 indoor-rated enclosure, intended for clean, dry locations where accessibility and protection are both important.

Industrial Components Built for Long-Term Operation

At the heart 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 with repeated heavy startups.

Combined with solid-state digital control, these components make the SB-30 a long-term power solution rather than a temporary workaround.
