Resistors, dedicated for use with MCRF 400W 50 OHM frequency inverters

Braking resistors are a key component of installations with frequency inverters, used to safely dissipate the energy generated during motor braking. Their function is to convert kinetic energy into heat, preventing exceeding the permissible voltages in the inverter's DC link and potential damage to the device.

This model, with a power of 400W and a resistance of 50 Ohm, is dedicated to working with LS Electric inverters, although it can be used in systems from other manufacturers. Selecting the appropriate braking resistor depends on the motor power and inverter operating parameters – a resistor that is too small will not provide sufficient braking, while one that is too large may overheat.

Application and benefits:

• Effective braking: The resistor enables controlled motor braking, which is particularly important in applications requiring precise positioning or rapid stopping.
• Inverter protection: By dissipating braking energy, the resistor protects the inverter from damage caused by overvoltage.
• Compact dimensions: Allow for mounting in limited space.
• Safe design: Ensures safe operation of the device.
• Wide range of applications: Can be used with various types of motors and inverters (according to power parameters).

These types of resistors are used in many industries, including:

• Lifting systems
• Packaging machines
• Transport applications (e.g., conveyors)
• Devices requiring precise motion control

Selecting a resistor with the appropriate power and resistance is crucial for the correct operation of the braking system. It is important to consider the load characteristics and braking duration to avoid overheating the resistor. Remember to provide adequate ventilation in the installation location to effectively dissipate the heat generated during operation.
