1、 Product Overview
MAGNETEK EDB4021ET is a dynamic braking resistor designed specifically for use with frequency converters. Its main function is to absorb regenerative energy during motor braking or deceleration, convert it into thermal energy, and release it to prevent the bus voltage of the frequency converter from being too high, thereby protecting the stable operation of the drive system. This resistor is widely used in industrial equipment with high inertia or frequent start stop requirements.
2、 Technical parameters (typical)
Model: EDB4021ET
Voltage level: 460V AC
Power matching: suitable for AC motors of approximately 15 HP
Adaptive current: approximately 24 A (full load current)
Type: Class D dynamic braking resistor
Installation method: Modular installation inside or outside the cabinet
3、 Application Fields
Lifting and hoisting equipment
Cranes, electric hoists, lifting platforms and other equipment frequently start and stop, generating regenerative energy during the braking process. EDB4021ET can effectively absorb this energy, protecting the frequency converter and ensuring stable operation of the power grid.
Elevator and Cableway System
During the descent or deceleration phase of the elevator, the motor will feedback energy, and the resistor will absorb the electrical energy in a timely manner and convert it into heat, ensuring a smooth and safe braking process.
Conveyor and handling system
Used in equipment such as logistics conveyor belts, automatic stacking systems, robot arms, etc. that require rapid start stop to prevent the impact of regenerative voltage on the control system.
High inertia fan and water pump system
Large fan or pump equipment will release a large amount of energy due to inertia during emergency shutdown, and EDB4021ET can effectively prevent overvoltage situations from occurring.
Metallurgy and Mining Machinery
During the emergency stop phase after high-speed or heavy-duty operation, feedback current is quickly consumed through resistors to prevent equipment damage and improve system reliability.
