Smart-Boost SB-40 Digital Rotary Phase Converter

The Smart-Boost SB-40 is a high-capacity digital rotary phase converter built 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 smoothly and reliably.

This unit is designed for operations where startup issues are not just annoying, they are expensive. If motors downstream struggle to overcome inertia, hesitate under load, or fail to start consistently, the SB-40 is engineered specifically to solve that problem.


Built for Large, Hard-Starting Industrial Equipment

The SB-40 is intended for large air compressors, submersible pumps, flywheel-driven systems, gearhead lathes, and other high-inertia three-phase machinery. These machines often demand several times their normal running current at 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 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-40 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 practical terms, this results in stronger motor starts, smoother transitions to operating speed, and cleaner power behavior in demanding industrial environments.


Smooth Starts and Efficient Power Delivery

Soft-start functionality reduces mechanical and electrical shock during startup. Motors ramp up smoothly instead of pulling aggressively, helping extend the service life of both the 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-40 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 complex industrial setups.

All components are housed in a NEMA 1 indoor-rated enclosure, intended for clean, dry environments 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-40 a long-term power solution rather than a temporary workaround.

High-Capacity Startup Power for Industrial Operations

The Smart-Boost SB-40 is built for operations where startup performance directly impacts productivity and equipment longevity. By delivering intelligent, high-current support precisely when it is needed, it provides a dependable way to run demanding three-phase equipment from single-phase power.

Energy Systems Central supplies power solutions designed for real industrial challenges. The Smart-Boost SB-40 reflects that approach, precise, robust, and engineered for equipment that needs more than standard phase conversion.

Soo good!
Size: 8 Fl Oz (Pack of 1)
Love this product! Im so greatful to have found this through Nina Pool (thank u Nina!) After trying multiple different face washes that left my sensitive skin feeling tight and irritated, im so glad to have tried this one. It's a gel like consistancy thats gentle, hydrating and leaves my face feeling softer and cleaner than any other product ive tried. Ive ordered this product many times. I hope they never discontinue this.

Best Facewash
Size: 8 Fl Oz (Pack of 1)
Favorite face wash ever. No harsh smells or 'chemically' feel. Creates a nice bit of suds and leaves your skin feeling soft and really clean. Compared to other face washes, it is not too expensive for a great product.

Best for normal/dry skin 9/10
Size: 8 Fl Oz (Pack of 1)
Been using this cleanser for over a year now and I love it that it doesn’t strip my skin while leaving it still clean! Super gentle and no fragrance.

Great for oily skin & makeup removal
Size: 8 Fl Oz (Pack of 1)
Great for oily skin & makeup removal. Because I’m so oily, I usually wash my face twice to get all the oil & makeup off, but this is pretty good for 1 use, & also feels nice & clean without stripping & no fragrance at all.
