Braking resistors for inverters – a key to effective braking

The MCRA 150W 600 OHM braking resistor is an element dedicated to working with frequency inverters. Its task is to dissipate excess energy generated during motor braking, converting it into heat. This is crucial for ensuring stable operation of the inverter and avoiding errors related to exceeding the permissible voltage in the DC link circuit.

How does a braking resistor work?

During motor braking, kinetic energy is converted into electrical energy. If this energy is not properly dissipated, the voltage in the inverter circuit may increase, leading to its shutdown. The braking resistor absorbs this energy and dissipates it as heat, keeping the voltage at a safe level. Selecting the appropriate resistor, such as the MCRA 150W 600 OHM, is essential for ensuring effective and controlled braking.

Features and application of the MCRA 150W 600 OHM resistor

This specific model of resistor with a power of 150W and a resistance of 600 Ohm is designed to work with inverters with a power of approximately 0.75 kW. It is an ideal solution where effective motor braking is required while maintaining the reliability of the entire system. Compact dimensions and a safe housing facilitate installation and ensure safe operation. Resistors from the MCRA series are specially designed for LS Electric inverters, which guarantees optimal compatibility and performance. Selecting a resistor with the appropriate power (in this case 150W) and resistance (600 Ohm) allows for effective dissipation of braking energy with the assumed braking time (ED=5%). Increasing the braking time requires the use of a resistor with higher power while maintaining the same resistance value.
