Product Description
25KW Braking Resistor Box for Inverter & VFD Applications
High Power Dynamic Braking Resistor Cabinet for Motor Drive Energy Dissipation
The 25KW 3.6RJ Braking Resistor Box is a high-performance dynamic braking solution engineered for inverter and VFD-driven motor systems requiring fast, stable, and safe deceleration. During motor braking, rapid speed reduction, or emergency stop conditions, regenerative energy flows back into the inverter's DC bus. Without proper dissipation, this excess energy can cause DC bus overvoltage, inverter trips, or permanent equipment damage. This braking resistor box efficiently converts regenerative electrical energy into heat, ensuring system stability and protecting critical drive components.
Technical Specifications & Construction
With a rated power of 25KW and resistance value of 3.6RJ, this braking resistor box delivers reliable energy dissipation performance under frequent braking cycles and high-load conditions. The internal construction features high-quality aluminum case resistors that provide exceptional heat dissipation, stable resistance values, and robust mechanical durability. The aluminum housing offers superior thermal conductivity, enabling rapid heat transfer and release for enhanced braking efficiency and extended resistor element lifespan.
Industrial Applications
This 25KW 3.6RJ Braking Resistor Box is widely utilized across various industrial equipment including:
- Cranes and hoists
- Elevator systems
- Conveyor systems
- Machine tools and rolling mills
- Injection molding machines
- Winders and high-inertia motor applications
In lifting and lowering systems, it effectively absorbs potential energy during load descent, preventing inverter overvoltage alarms and enhancing braking safety. For applications with frequent start-stop operations, it improves deceleration response, reduces mechanical stress, and ensures smooth motor control.
Design & Integration Features
Engineered with a robust enclosure and efficient ventilation structure, this braking resistor box is built for continuous industrial operation in demanding environments. It offers seamless integration with various inverter brands and control systems, providing a cost-effective and dependable solution for energy dissipation, system protection, and dynamic braking in modern motor drive applications.
