Braking resistors for frequency inverters

Braking resistors, such as the MCRF 300W 600 OHM model, are a key element of motor control systems 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 voltages in the inverter's DC link and protects it from damage.

Construction and application

This specific model, with a power of 300W and a resistance of 600 Ohm, is dedicated to working with LS Electric inverters. These types of resistors are used in situations where excessive energy is generated during motor braking, which must be effectively dissipated. They are particularly useful in applications requiring frequent and dynamic braking, such as cranes, hoists or packaging machines. The resistance value of 600 Ohm makes this resistor work well in systems with specific operating parameters - selecting the appropriate value is crucial for the correct functioning of the braking system.

Key features and benefits

• Compact dimensions: The dimensions of the resistor are 190 x 70 x 45 mm, which makes it easy to mount even in limited space.
• Safe construction: The housing provides protection against external factors and minimizes the risk of mechanical damage.
• Dedicated to LS inverters: Optimized for cooperation with LS Electric frequency inverters, which guarantees reliable operation and compatibility.
• Effective energy dissipation: Allows for safe motor braking without the risk of damage to the inverter or other system components.
• Durability and reliability: Made of high-quality materials, they ensure long life and stable operation in various environmental conditions (operating temperature from -55°C to 200°C).
• Installation protection: Protects the inverter from overvoltages generated during regenerative braking, increasing its lifespan and reducing repair costs.

User parameters

The MCRF 300W 600 OHM resistor is designed to operate at a voltage of 400V. Its rated power is 300W, making it a suitable choice for applications requiring moderate braking. It is important to select the resistor correctly for the specifics of a given drive system - a resistor with too little power can overheat and be damaged, while a resistor with too much power can be uneconomical.
