Resistors, dedicated for use with MCRF-ST 7.2kW frequency inverters 8.4 OHM MCRF-ST 7.2KW 8.4 OHM

Frequency inverter resistors – effective braking and motor protection

Resistors dedicated to working with LS Electric frequency inverters, such as the MCRF-ST 7.2kW 8.4 OHM model, play a key role in regenerative braking systems. Their task is to dissipate excess energy generated during motor braking, converting it into heat. The use of a braking resistor allows for effective stopping of the drive, minimizing the load on the power grid and increasing the safety of the entire system.

Construction and application

MCRF-ST series resistors are specially designed to work with LS Electric inverters, ensuring optimal performance and reliability. They are used in applications requiring frequent braking or sudden load changes, such as cranes, elevators, conveyors or machines controlled by induction motors. Compact dimensions facilitate installation even in limited space. A safe housing protects against accidental contact and ensures long-term operation.

Key features and benefits

• Dedicated to LS inverters: They ensure a perfect fit and optimal cooperation with LS Electric devices, guaranteeing maximum braking efficiency.
• Wide power range: Available in various power ratings (from 120 W to 100 kW), allowing you to select a resistor suitable for a specific application and motor power.
• Compact design: They take up little space, making it easier to integrate with the existing electrical installation.
• Safety of use: A durable housing protects against mechanical damage and ensures operator safety.
• Effective energy dissipation: Effectively dissipate thermal energy, preventing the inverter from overheating and extending its service life.
