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.

True to Description
Color: Black, Size: 4 Panel
Love it!! I bought it for privacy while the nurse is dressing my dad. There were several colors black matched the decor . It blocked the sunlight and street lights. Durability and quality very good. Easy closure when not in use. Lightweight. No assembly needed

Nice room divider!
Color: White, Size: 8 Panel
The white panels are a nice off-white color. shipped in perfect condition. Already assembled so set up was quick. We use them to separate a photo studio from the main entry. Easily covers a 6 Ft. opening to the room. They are a woven material with wood colored sticks to support the weave. They are about 6 Ft. tall at the top of the curved section but less at the hinged sections. Light and easy to set up and take down. We are straddling two different floors so the extended legs at the bottom make this easy. Not sure how to clean them but they look great so far!

Instant Privacy
Color: Beige, Size: 8 Panel
Bought this to separate a ground level living area used as an office. Works well to cover visual clutter; allows a clean look when entering the front door. Comes fully assembled. Hinges are sturdy enough, as long as the panels aren’t stretched too far; have to allow some bend between them. For the price point, quality and functionality are satisfactory.

Great Divider, Just Needed Anchoring for Outdoor Use
Color: Grey, Size: 6 Panel
This room divider is very nice—stylish, lightweight, and easy to set up. I’m using it outdoors, which may not be its intended use, and I found that wind can knock it over pretty easily. Once I anchored it down, though, it worked just fine and looks great in the space. Indoors, I imagine it would be perfect right out of the box. Overall, a solid purchase with just one small adjustment needed for my setup.

Good Quality
Color: White, Size: 4 Panel
They are made with good quality. However I bought them to help with blocking outside light and the white does not do that.
