Braking resistors for frequency inverters

These resistors are a key element of regenerative braking systems in inverters, enabling safe and efficient dissipation of energy generated during motor braking. Using a braking resistor prevents exceeding the permissible voltage in the inverter's DC link, protecting it from damage and ensuring the continuity of the braking process.

When the motor enters generator mode (e.g., during deceleration), the generated energy must be dissipated. The braking resistor converts this energy into heat, effectively dissipating it and keeping the voltage within safe limits. This is particularly important in applications requiring frequent and dynamic braking, such as cranes, elevators, or industrial machines.

Characteristics and application

MCRF 600W 60 OHM resistors are dedicated to working with LS Electric inverters, providing optimal operating parameters and reliability. They are designed with compact dimensions and a safe enclosure in mind, which facilitates installation and provides protection against external factors. This makes them suitable for use in both industrial environments and more demanding operating conditions.

Selecting the appropriate braking resistor is crucial for the correct operation of the system. It is necessary to consider the motor power, braking time, and inverter characteristics. A resistor that is too small may not be able to effectively dissipate the energy, leading to inverter errors and limiting braking functionality. Conversely, a resistor that is too large may cause unnecessary energy losses and extend the braking time.
