Product Features
The resistor measures 165mm in length, 60mm in width and 30mm in height. This compact design makes it more convenient to install and use. It not only saves space but also can be conveniently integrated into various compact electrical control cabinets and equipment.
Customization service: Please tell me the power and resistance value you need to customize.
Application scenarios
Motor speed regulation system
In the motor speed regulation system, when the motor needs to decelerate rapidly or stop, a large amount of regenerative electrical energy is generated. The 200W braking resistor can promptly absorb and consume this electrical energy, preventing the motor and frequency converter from being damaged due to overvoltage.
Lifting equipment
When a crane is lifting and moving heavy objects, the reverse movement of the motor generates regenerative energy. The 200W braking resistor can effectively consume this energy, ensuring the stability and reliability of the control system of the lifting equipment.
Automated production line
In an automated production line, the frequent start-stop and speed changes of various motors generate a large amount of regenerative electrical energy. The 200W braking resistor can ensure the stable operation of the electrical system of the production line and improve production efficiency.
