Braking resistors for frequency inverters

Braking resistors, such as the MCRA 150W 150 OHM model, are a key element of motor control systems using frequency inverters. Their task is to effectively dissipate the energy generated during motor braking, converting it into heat. Without a braking resistor, excess energy could damage the inverter or other installation components.

This specific model, with a power of 150W and a resistance of 150 Ohm, is designed to work with LS Electric inverters, although it can be used in many other systems. Its compact dimensions (182 x 43 x 20 mm) make it easy to install even in limited space. A solid housing ensures safe use and durability.

Construction and application

The MCRA 150W 150 OHM braking resistor is a passive element, which means it does not require an external power supply. It is connected to the inverter output dedicated to regenerative braking. When the motor brakes, kinetic energy is converted into electrical energy, which, instead of returning to the grid (which could overload it), is dissipated as heat on the resistor.

The use of a braking resistor is particularly important in applications requiring frequent and rapid motor stopping, such as cranes, elevators, conveyors or CNC machines. This allows for smooth and controlled braking without the risk of damage to the inverter or other drive system components.
