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.

Sent Wrong Pieces
Size: 1 Panel, Size: 1 Panel
I really, really wanted to like this - and, in theory, I really, really should have! The instructions were easy to follow and assembly took about five minutes. The assembled screen is lightweight and easy to move. It was a great size and exactly what I was looking for except....I wasn't sent the correct pieces. Instead of receiving 4 elbow pieces and 4 feet, I received 2 elbow pieces and 8 feet - meaning that the bottom part of the fabric just hangs there and, overall, the divider is extremely unstable because there is no horizontal support on the bottom. Thankfully, there are Velcro tabs on the side of the fabric so I can use it if I don't plan to move it even 1 cm, but otherwise, what I received is not usable for what I needed it for. Additionally, the fabric is made of polyester and catches animal hair very easily. Had I received the correct pieces, this would be a good buy for the money. Unfortunately, overall, I'm disappointed.

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.

Very useful
Color: Black
I’ve been using this room divider to separate my space from my daughter’s, and it has worked out really well. It provides just the right amount of privacy while still keeping the room feeling open and comfortable. The design is simple yet stylish, so it blends nicely with our decor. It’s also lightweight and easy to move when needed, which is a big plus. The material feels durable and well-made, not flimsy at all. Overall, it’s a practical and attractive solution for shared spaces, and I’m very happy with this purchase. I would definitely recommend it to others.

Great Room Divider
Color: Black
This product is a great room divider that decent quality and worth the price tag. The look is sleek and fits seamlessly into any room without complaint. The assembly was easy to follow and the quality is long lasting. Not only that, I need it as my sons share a room and we’re looking for some privacy. The divider is able to extend across a decently large area really divide the room as it has 4 panels. Overall, this is a great product for its cost and if your looking for a room divider that’s not too costly, this is the pick.

Great for creating a workspace
Color: Grey
I needed a room divider that could be easily folded for storing to put behind my chair during my work calls. This works perfectly! Was very easy to put together. Lightweight but sturdy enough that it won’t fall over.
