Customization service: Please tell me the power and resistance value you need to customize.
Excellent heat dissipation performance: The aluminum shell brake resistor uses an aluminum shell as the shell material. Aluminum has good thermal conductivity and can quickly dissipate the heat generated by the resistor, ensuring the stability of the resistor during high-power operation.
Sturdy and durable structure: The aluminum shell brake resistor is designed with a sturdy structure, capable of withstanding mechanical vibration and shock. Its aluminum shell material not only provides excellent heat dissipation performance, but also enhances the mechanical strength of the resistor and prolongs its service life.
Easy to install and maintain: The aluminum shell brake resistor has a simple structure, is convenient to install and has a low maintenance cost. Its standardized external dimensions and installation holes enable it to be conveniently integrated into various devices.
Application scenarios
Frequency converter:In the frequency converter, the aluminum shell braking resistor is used during the deceleration and braking process of the motor to consume the regenerative energy generated by the motor, ensuring the stable operation of the frequency converter.
Servo system: In a servo system, aluminum housing braking resistors are used to regulate the motor's speed and torque, ensuring precise control of the servo system.
In the rectifier, the aluminum shell braking resistor is used to regulate the current and voltage to ensure the normal operation of the rectifier.
Inverter: In the inverter, the aluminum shell braking resistor is used for current sampling and voltage feedback, ensuring the stability and efficiency of the inverter.
Rectifier: In the rectifier, the aluminum shell braking resistor is used to regulate the current and voltage to ensure the normal operation of the rectifier.
