Why Choose the Unitronics UMI-S0053 Braking Resistor?
The Unitronics UMI-S0053 is a robust dynamic braking resistor designed for use with compatible Unitronics variable frequency drives (VFDs). It dissipates regenerative energy produced during motor deceleration, allowing the drive to stop motors more quickly while preventing DC bus overvoltage conditions.
When an AC motor slows down, the stored kinetic energy causes it to behave like a generator and feed energy back into the drive. Without a braking resistor this energy can increase the DC bus voltage and trigger drive faults. The UMI-S0053 converts this excess energy into heat, ensuring controlled braking and stable drive operation in industrial automation systems.
Designed for automation environments, the UMI-S0053 is typically used with drive systems around 2.2 kW (3 HP). Its rugged construction makes it suitable for installation in control panels and machinery where rapid deceleration or frequent stopping cycles are required.

Frequently Asked Questions
What is the UMI-S0053 used for?
The UMI-S0053 is a braking resistor used with a VFD to dissipate regenerative energy produced when a motor decelerates.
Why are braking resistors required in VFD systems?
When a motor slows down it can generate electrical energy that flows back into the drive. A braking resistor safely converts this energy into heat to prevent overvoltage faults.
What drive power range is this resistor designed for?
The UMI-S0053 is typically used with drives rated around 2.2 kW (3 HP).
What voltage systems can it be used with?
This braking resistor is designed for systems operating around 200 to 240 V AC and can be used with both single-phase and three-phase drive configurations.
Trusted by Automation Engineers
Dynamic braking resistors are widely used in industrial VFD systems to ensure safe motor deceleration and protect drives from regenerative overvoltage.
