Power Resistors are high-capacity resistive components designed to safely dissipate electrical energy as heat under heavy load conditions. They are commonly used for current limiting, load testing, voltage division, dynamic braking, and energy absorption in power systems. Built to handle high energy surges, these resistors are engineered with robust materials such as stainless steel grids, wire-wound elements, or metal film construction to ensure durability, thermal stability, and long service life.

Braking Resistors, a specific type of power resistor, are used with Variable Frequency Drives (VFDs), inverters, and electric motors to absorb excess regenerative energy during braking. When a motor decelerates, it acts as a generator, sending energy back to the drive’s DC bus. If this energy is not controlled, it can cause overvoltage faults or damage equipment. Braking resistors safely dissipate this energy as heat, ensuring controlled deceleration, protecting the drive, and extending the life of the motor and associated components.
