Smart-Boost SB-50 Digital Rotary Phase Converter

The Smart-Boost SB-50 is a high-capacity digital rotary phase converter built 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 cleanly, reliably, and without repeated attempts.

This unit is designed for operations where startup failures are not an inconvenience, they are a liability. If motors downstream hesitate, stall under load, or struggle to overcome inertia, the SB-50 is engineered specifically to eliminate those issues.


Built for Extreme Hard-Starting Industrial Equipment

The SB-50 is intended for 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 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-50 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 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 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 better motor response and more predictable performance under heavy load.


Integrated Controls and Built-In Protection

The Smart-Boost SB-50 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 environments.

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-50 a long-term power solution rather than a temporary workaround.

  • Submersible pumps and pump systems

  • Gearhead lathes and flywheel-driven machinery

  • High-inertia or heavy-load three-phase motors

  • Industrial environments where startup reliability is mission-critical


Maximum Startup Power for Industrial Operations

The Smart-Boost SB-50 is built for operations where startup performance directly impacts productivity, safety, 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-50 reflects that approach, precise, robust, and engineered for equipment that simply cannot afford weak starts.

Update: replacement comforter is much better… really impressed with this small business
Size: Palatial King
Update: The comforter on my bed is now everything I hoped for: fluffy, warm, and wonderfully cozy. Getting here was a two-part story, and it’s the happy ending and the fantastic service that created it that I really want to share. I’ll be honest, my first comforter was a letdown. It arrived flat and thin and just never really… fluffed into the cozy cloud I was hoping for. I was pretty frustrated, which is why I left my original review. But then, something really nice happened. The company actually reached out to me directly. They were so kind, listened without getting defensive, and genuinely wanted to make it right. They sent a replacement, no questions asked, and the difference has been night and day. This new one is exactly what I’d imagined. It has a real, fluffy loft, it’s softer, and after letting it settle, it’s become the full, warm, and comfortable comforter I wanted from the start. My quick takeaways: · A small business that stands behind their work. This meant a lot. · Customer service was top-notch kind, FAST, and professional. · The replacement is clearly better quality: fuller, softer, and warmer. · It’s a completely different (and better) experience than the first. I really value when a company just focuses on fixing things. The way they handled this completely changed my perspective. While the first one missed the mark, their response and the quality of the replacement have made me a happy customer. I’m glad I gave them the chance to make it right, and I’m finally cozy under the comforter I was hoping for.

Very Nice Comforter
Size: King
So far, very happy with my purchase, (King size comforter). Just received yesterday, unpackaged and put inside my duvet, then realized the instructions recommend you place it in the dryer, (as it comes vacuum packed). I really didn’t feel like messing with the duvet again and yet the comforter still fluffed out very nice. The outer shell is very soft, it has decorative piping around the edges and the filling is evenly spread out throughout all the pockets. One of the nicest features are the tabs, located on all four corners and in the middle of each side, (to tie to the inside of your duvet, if your duvet has the little inner strings) great for keeping the comforter in place.

Just one con…
Size: Palatial King
Loved everything about this duvet: great quality, true-to-size, 8 ties and REALLY big & fluffy. It was just way too warm for us, even during the winter. Wish we could find a duvet this full that was cooler.

MASSIVE SIZE
Size: California King
I cannot tell you how soft this is but it's like a cloud made of cotton candy! It's so soft and fluffy! In arizona its too hot for a blanket like this most of the time but this is also really cooling. Its been great, I dont have a big washing machine so i take it to the laundromat and its still in really good shape. Its clean and looks so soft and beautiful
