When your VFD is braking, energy created from the braking process must go somewhere. Without a properly sized braking resistor, this energy often can build faster than your drive can handle during deceleration or overhauling loads, leading to overvoltage trips, longer or limited deceleration, unstable controls, and or shortened component life.

Here at Bonitron, we support everything from washdown environments to megawatt class systems.

In need of a resistor that can handle tough environments? Bonitron case resistors are available in IP 65 rated up to 10 HP, offering protection to dust and high pressure water ingress, making these resistors an ideal choice for washdown environments.

For higher power applications, we offer the M3775R Resistive load bank line, built for braking requirements up to the megawatts!

The recent ice storms remind us of a hard truth:
You can't control when disruptions happen, but you can control how your system responds.

At Bonitron, we design solutions for the "when," not the "if."
Our S3460BR Ride-Thru System helps industrial and commercial VFD systems maintain DC bus power during power quality events such as voltage sags or brief outages by supplying energy from an integrated battery-based energy storage system. This allows critical drive-powered processes to continue operating through disturbances that would otherwise cause shutdowns or faults.

This message isn't about residential power or downplaying the challenges communities face during severe weather. It's about helping manufacturers, facilities, and operators build resilient systems that reduce downtime and recover faster when conditions become unpredictable.

Preparedness isn't about fear; it's about continuity.

Today we are bringing you an overview of our UPD (Uninterruptable Power for Drives) systems. Our systems are designed to keep your VFDs running through power disturbances. Whether it be a sag or full outage.

Our UPD systems come in multiple rating sizes (see video for specific ranges).

Give us some feedback and let us know what you would like to see from us next.

Until next time!

Bonitron UPD (Uninterruptible Power for Drives) Systems include a DC Voltage Regulator that monitors the drive. If the drive voltage sags or disappears, the ...

We would love to hear some feedback on the new design of the website. What are some things you really like? What you don't like? And what would you like to see us implement in the future?

Bonitron UPD Systems are perfect for critical, drive-driven processes. UPD Systems connect to drive DC terminals and monitor the drive's voltage. If the voltage drops, the Bonitron UPD immediately supplies power directly to the DC bus, eliminating wasteful DC/AC conversions.
