A distribution box is a low-voltage distribution box composed of switchgear, measuring instruments, protective appliances, and auxiliary equipment assembled in a closed or semi closed metal cabinet or screen according to electrical wiring requirements.
Scope of application:
The street light control box is used to control street lights, tunnel lights, community lights, landscape lights, square lights, and other related street lights.
Automatic transfer switchgear is used for automatic transfer between the main power supply (mains) and the backup power supply (generator set or other power sources), with reliable operation, simple use, compact structure, and high cost-effectiveness.
The water pump control cabinet has multiple protection functions and complete status display, including overload, short circuit, phase loss protection, pump body leakage, motor overheating and leakage protection. It also has single pump and multi pump control working modes, multiple main and backup pump switching modes, and various starting modes.
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.
