UMI-S0070 Unitronics UMI 1.5-2.2kW Mounting Plate

Why Choose the Unitronics UMI-S0070 Braking Resistor?

The Unitronics UMI-S0070 is a heavy-duty dynamic braking resistor designed for use with compatible Unitronics variable frequency drives (VFDs). Engineered for high-power industrial applications, it safely dissipates regenerative energy generated during motor deceleration, helping improve braking performance, protect drive electronics and prevent DC bus overvoltage faults.

During rapid motor deceleration, excess energy is returned to the drive's DC bus. The UMI-S0070 converts this regenerative energy into heat, allowing the drive system to maintain stable operation while delivering faster and more controlled stopping performance. This makes it particularly suitable for cranes, hoists, conveyors, heavy industrial machinery and other high-inertia applications.

Designed for 400-480 V AC three-phase systems, the UMI-S0070 provides reliable regenerative energy dissipation for high-power drive installations. Its industrial-grade construction ensures dependable operation in demanding manufacturing, material handling and automation environments.

Reliable Dynamic Braking for Industrial Drive Systems

Braking resistors are essential components in variable frequency drive systems where motors frequently decelerate under load. During braking, regenerative energy is returned to the drive DC bus. The UMI-S0070 safely dissipates this excess energy, helping maintain stable drive operation while enabling faster and more controlled stopping performance.

This improves machine productivity, protects drive electronics and enhances operational safety in applications requiring rapid speed changes, high-inertia braking or precision motor control.
