The embedded high-voltage soft starter is a new type of integrated starting device that combines multiple functions, meeting the starting needs of both asynchronous and synchronous motors. The product integrates starting, display, protection, and built-in current and voltage data collection into a motor terminal control device. Users only need to configure bypass switch equipment to implement a complete solution, making connections simple and easy to understand. The complete solution can achieve more complex control functions. The product features a built-in LCD screen for data reading and parameter modification, and parameters can also be adjusted via infrared remote control. Users can opt for external instruments that transmit the current and voltage data of the equipment through communication methods.

　　The embedded high-voltage soft starter is suitable for starting AC motors with a rated voltage of 3-10kV. The product is widely used in industrial fields such as large steel, petroleum, chemical, aluminum, fire protection, mining, sewage treatment, and power, and can be well matched with motor-driven equipment such as pumps, fans, compressors, crushers, mixers, and various electromechanical devices.

　　The embedded high-voltage soft starter is a new type of motor starting device suitable for squirrel-cage asynchronous and synchronous motors. It is a terminal control device that integrates starting, display, protection, and data collection. Users can achieve complex control functions with fewer components. The embedded high-voltage soft starter controls the output voltage by adjusting the conduction angle of the thyristor through optical fiber, changing the voltage value at the motor stator terminal, thus controlling the starting torque and starting current of the motor, achieving soft start control. The embedded high-voltage soft starter can smoothly accelerate according to the set starting parameters, reducing electrical and mechanical shocks to the power grid, motor, and equipment. When the motor reaches the rated speed, the bypass contactor is automatically connected. After the embedded high-voltage soft starter completes the start, it continues to monitor the motor and provides various fault protections.
