1、 Product Overview
MAGNETEK EDB4021ET is a dynamic braking resistor designed specifically for frequency converters. Its core function is to absorb the regenerated energy generated when the motor is in a braking or deceleration state, and convert this energy into heat energy to be released. This process can effectively prevent the bus voltage of the frequency converter from being too high, thereby ensuring the stable operation of the drive system. This resistor is widely used in industrial equipment with high inertia characteristics 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: Equipment such as cranes, electric hoists, and lifting platforms have frequent start stop situations and generate regenerative energy during braking. EDB4021ET can effectively absorb this energy, thereby protecting the stable operation of the frequency converter and the power grid.
Elevator and Cableway System: When the elevator is in the downward or deceleration stage, the motor will experience energy feedback. This resistor can absorb electrical energy in a timely manner and convert it into heat, ensuring a smooth and safe braking process.
Conveyor and handling system: It plays a role in equipment such as logistics conveyor belts, automatic stacking systems, and robot arms that require rapid start stop, and can prevent the impact of regenerative voltage on the control system.
High inertia fan and pump system: Large fan or pump equipment will release a large amount of energy due to inertia during emergency shutdown, and EDB4021ET can effectively avoid overvoltage situations.
Metallurgy and mining machinery: During the emergency stop phase after high-speed or heavy load operation of equipment, resistors can quickly consume feedback current, prevent equipment damage, and improve system reliability.
