Braking resistors for inverters – effective energy dissipation

Braking resistors, such as the MCRF 400W 200 OHM model, are a key element of motor control systems using frequency inverters. Their task is to safely dissipate excess energy generated during motor braking, converting it into heat. Without a braking resistor, this energy could lead to damage to the inverter or disturbances in its operation.

This specific model, with a power of 400W and a resistance of 200 Ohm, is dedicated to working with LS Electric inverters and finds application in motors with a power of up to 2.2kW. Selecting the appropriate resistor is essential to ensure the correct operation of the braking system and protect the installation elements.

Construction and application

The MCRF 400W 200 OHM resistor is characterized by its compact dimensions (220 x 70 x 45 mm) and solid construction. Made of resistance wire wound on a metal body, it provides high resistance to mechanical and thermal damage. The metal housing effectively dissipates heat, which translates into stable operation even under high loads.

The use of braking resistors is particularly important in applications requiring frequent and rapid motor braking, such as cranes, elevators, packaging machines or conveyors. They allow for smooth stopping of the drive without the risk of overloading the inverter and ensure the reliability of the entire system.

Key features and benefits

• Dedicated to LS Electric inverters: Ensures optimal cooperation with devices from this manufacturer.
• Power 400W and resistance 200 Ohm: Appropriate parameters for motors with a power of up to 2.2kW.
• Compact dimensions: Facilitate mounting even in limited space.
• Durable construction: Metal body provides resistance to mechanical and thermal damage.
• Effective heat dissipation: Ensures stable operation of the device under high loads.
• Inverter protection: Protects against damage caused by excessive voltage during braking.
• Smooth braking: Enables controlled stopping of the motor without jerks and overloads.
• Duty cycle ED=5%: Standardly designed for operation with a 5% duty cycle, which means it can operate at full power for a short time and then requires rest. To extend the operating time, a resistor with a higher power should be selected.

Choosing the right braking resistor guarantees the reliable operation of the drive system and the safety of the entire installation. The MCRF 400W 200 OHM model is a proven choice for a wide range of industrial applications.
