The variable frequency control board is mainly used to adjust the working frequency of equipment, reduce energy loss, and can smoothly start the equipment, reducing the damage to the motor caused by the large current generated when the equipment is directly started. Simultaneously equipped with analog input (for speed control or feedback signals), PID control, pump switching control (for constant pressure), communication function, macro function (with different parameter settings for different occasions), multi stage speed, and so on.

A three-phase anti-parallel thyristor is used as a voltage regulator. The input voltage of the motor is adjusted by controlling the conduction angle of the thyristor, thereby achieving smooth starting and stopping.
PLC uses a cyclic scanning method to process input and output signals. For large systems, interruption method can also be used to improve response speed.
Petrochemical electrical distribution panels are usually combined with DCS (distributed control system) to achieve precise control and regulation of the production process, ensuring production stability and efficiency.
Soft start control cabinet is an electrical equipment used for motor control, which can reduce the starting current, reduce the impact on the distribution system, and extend the service life of the motor and related equipmen
electrical control cabinet
Electrical control cabinet, also known as electrical control cabinet, is a type of equipment that assembles switchgear, measuring instruments, protective appliances, and auxiliary equipment into enclosed or semi enclosed metal cabinets or screens according to electrical wiring requirements.
