Braking resistors for frequency inverters – a key to effective energy management

Resistors dedicated to working with frequency inverters (drives) play a key role in regenerative braking systems. Their task is to dissipate excess energy generated during motor braking, converting it into heat. Using a braking resistor prevents exceeding the permissible voltages in the inverter's DC circuit, protecting it from damage and ensuring stable system operation.

This model, with a resistance of 2.8 Ohm and a power of 24kW, has been specifically designed to work with LS Electric MCRF-ST series frequency inverters. It is a necessary component in applications requiring frequent braking, such as cranes, elevators, conveyors or CNC machines.

Design and application

The MCRF-ST 24kW 2.8 OHM resistor is characterized by a compact design and a safe housing, which facilitates installation and provides protection against mechanical damage. The use of high-quality materials guarantees reliability and long life even in demanding working conditions. The resistance value has been precisely selected to ensure optimal energy dissipation for inverters with a power of 24kW.

Using this resistor allows for:

• Effective motor braking: Provides smooth and controlled stopping of the driven motor.
• Inverter protection: Protects the inverter from overload and damage caused by excessive DC voltage.
• Increased energy efficiency: Allows for energy recovery during braking and its controlled dissipation.
• Reduced operating costs: Reduces the risk of inverter failure and associated repair or replacement costs.

Key product features

The MCRF-ST 24kW 2.8 OHM resistor stands out from the competition primarily due to its dedicated compatibility with LS Electric inverters. This means a perfect match of electrical and mechanical parameters, which translates into seamless integration with the system and optimal performance. In addition, the compact dimensions facilitate installation even in limited space. It is worth paying attention to the solid construction and high quality of workmanship, which guarantee reliable operation for a long time. Therefore, investing in this resistor is a guarantee of stable operation of the braking system and protection of valuable equipment – the inverter.
