Embedded high-voltage soft starter is a new type of starting equipment integrating multiple functions, which can meet the requirements of starting asynchronous motor and synchronous motor at the same time. Product integrated start, display. Protection, built-in current and voltage data acquisition in one of the motor end encounter control equipment. The user only needs to configure the bypass switch device to realize the complete set of solutions, the connection is simple and easy to understand. The complete set of solutions can realize more complex control functions. Product built-in LCD display can read data and modify the parameters, can also be adjusted by infrared remote control parameters. The user can choose to install the instrument outside the cabinet, and the installed instrument transmits the current current and voltage data of the equipment through communication.

The embedded high-voltage soft starter is suitable for starting AC motors with rated voltage of 3-10kV. The products are widely used in large-scale steel, petroleum, chemical, aluminum, fire protection, mining, sewage treatment, electric power and other industrial fields, and can be used well with motor drive equipment. Such as: water pump, fan, compressor. Shredder. Depending on the mixing machine, belt conveyor and other mechanical and electrical equipment.

Embedded high-voltage soft starter is a new type of motor starting equipment, which is suitable for squirrel-cage asynchronous and synchronous motors. It is a motor terminal control device integrating starting, display, protection and data acquisition. The user can implement more complex control functions with fewer components. The embedded high-voltage soft starter controls the output voltage through the conduction angle of the fiber-controlled thyristor, and changes the voltage value of the motor stator terminal, that is, controls the starting torque and starting current of the motor, so as to realize the soft start control of the motor. The embedded high-voltage soft starter can be smoothly accelerated according to the set starting parameters, thereby reducing the electrical and mechanical impact on the power grid, motors and equipment. When the motor reaches the rated speed, the bypass contactor is automatically turned on. The embedded high-voltage soft starter continues to monitor the motor after starting and provides various fault protections.
