Braking resistors for frequency inverters – effective energy dissipation

Braking resistors, such as the MCRF-ST 3.6kW 20 OHM model, are a key element in installations using frequency inverters. Their task is to safely dissipate the energy generated during motor braking, converting it into heat. Using a resistor prevents exceeding the permissible operating parameters of the inverter and ensures its reliable operation. This is particularly important in applications requiring frequent braking and starting cycles, where excess energy can lead to damage.

Design and parameters

The MCRF-ST 3.6kW 20 OHM resistor is designed specifically for use with LS inverters, offering optimal operating parameters and high efficiency. Its compact dimensions (550 x 260 x 126 mm) make it easy to install even in limited spaces. The use of high-quality materials and a solid construction ensure long-lasting and trouble-free operation of the device. Additionally, the resistor is equipped with a PTC sensor that monitors its temperature and protects against overheating.

Application and compatibility

This resistor model is dedicated to inverters with a power of 18.5 kW and 22 kW, as well as applications requiring 150% braking torque with an ED=5% duty cycle. This ensures effective motor braking and protection of the inverter against damage caused by excessive voltage. It is worth remembering that doubling the ED operating time also requires doubling the power of the resistor while maintaining the same resistance value. These resistors are used in a wide range of industries, including lifting applications, elevators, conveyors, and construction and agricultural machinery.
