Smart-Boost SB-60 Digital Rotary Phase Converter

The Smart-Boost SB-60 is a high-capacity digital rotary phase converter engineered for very 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 smoothly, reliably, and without repeated attempts.

This unit is designed for operations where startup failures are not tolerable. If motors downstream struggle with inertia, stall under load, or require excessive starting current that standard converters cannot provide, the SB-60 is built specifically to solve that problem.

Built for Extreme Hard-Starting Industrial Loads

The SB-60 is intended for very large air compressors, submersible pumps, flywheel-driven systems, gearhead lathes, and other high-inertia three-phase machinery operating at serious scale. These machines often require several times their normal running current during startup, which is where conventional rotary phase converters reach their limits.

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

How Smart-Boost Digital Control Works

At the core of the SB-60 is a Smart-Boost digital controller that uses solid-state relays to re-energize the 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 real-world terms, this means stronger motor starts, smoother transitions to operating speed, and cleaner overall power behavior in demanding industrial environments.

Smooth Starts and Efficient Power Delivery

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

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

Integrated Controls and Built-In Protection

The Smart-Boost SB-60 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 complex industrial installations.

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-60 a long-term power solution rather than a temporary workaround.
