Remote LED Lighting Control System with Smart PDU and Automatic Contactor Management

Project Overview
This LED remote control cabinet project is customized for Paraguay, mainly using ABB brand electrical equipment. Due to the different power of LEDs, the number of thermal relays, AC contactors, and time relays required also varies. Remote control across cities can be achieved by connecting VPN and routers through intelligent PDU. In addition, the system also has the function of automatically opening contactors in sequence to avoid voltage peaks.

Analysis of main equipment

• LED lights: As the controlled object, the power of LED lights directly affects the selection of required electrical equipment.
  
• Thermal relays: used to protect circuits from damage due to overload and overheating. It is very important to choose a suitable thermal relay according to the power of LED lights.
  
• AC contactors: used to control the switch of LED lights. Due to the different power of LED lights, the number of contactors required will also vary.
  
• Time relays: used to implement timing control functions, such as timing to turn on or off LED lights.

The control cabinet is equipped with multi-circuit circuit breakers and contactors, which can automatically open the contactors in sequence to avoid voltage peaks at startup and protect LED equipment from voltage shocks. In addition, the design of the control cabinet takes into account the convenience of maintenance, and the internal layout is clear, which is convenient for technicians to debug and maintain.
The control cabinet is suitable for various commercial and industrial environments, such as billboards, public information displays, stage lighting, etc., and can meet the needs of different customers. Its high-quality components and sturdy structure ensure long-term stable operation and low maintenance costs.
