Resistors, dedicated for use with MCRF 1kW 85 OHM frequency inverters MCRF 1KW 85 OHM

Braking resistors for frequency inverters

Dedicated resistors for use with inverters play a key role in effectively managing the energy generated during motor braking. When the motor enters generator mode, the resistor dissipates excess energy in the form of heat, preventing exceeding the permissible voltages in the inverter's DC link and potential failures. This particular model, with a power of 1kW and a resistance of 85 Ohm, is designed to work with LS frequency inverters.

Design and application

The MCRF 1kW 85 OHM resistor is characterized by a compact design and a safe housing, providing resistance to mechanical damage. It is a component intended for use in regenerative braking systems, where efficient energy dissipation is essential for the proper operation of the system. It finds application in a wide range of industrial applications where inverters are used to control the rotational speed of motors.

Resistor selection – what is worth knowing?

Selecting the right braking resistor is crucial for the proper functioning of the system. It is worth paying attention to the continuous power of the resistor and its resistance, matching them to the parameters of the inverter and the characteristics of the load. An incorrectly selected resistor can lead to overheating and even damage to the braking system components. In case of doubt, it is worth consulting a specialist or using the selection tools available from inverter manufacturers.
