In the LED display industry, the power distribution cabinet, as one of the core components, directly affects the stability and lifespan of the display due to the large instantaneous current during startup, caused by the numerous switching power supplies. As these displays are prone to impact the power grid, it is recommended to equip displays with a power rating exceeding 10KW with a dedicated intelligent power distribution cabinet for LED displays.
This product features an indoor housing with a total load power of 160KW, capable of connecting 48 single-phase electrical equipment (such as display circuits, air conditioning circuits, and fan circuits). It offers multiple protections including overcurrent and short-circuit protection, and supports manual power on/off and PLC-powered functions. Standard circuit breakers are from Delixi, while contactors are from Schneider Electric. PLC power supply utilizes high-reliability industrial-grade products from Mingwei, and controllers are from Omron, IPMS, or Siemens PLCs. It is equipped with RS232 and TCP/IP communication, allowing integration into central control systems for联动 control; and includes ports for smoke, temperature, and other sensors. It provides quick and convenient external data monitoring for LED display systems, with preset plans for cabinet, LED display overtemperature, smoke, and intrusion alarms. Through setting thresholds, it can automatically and intelligently control protection, enabling unattended operation. The system uses B/S architecture and is compatible with multiple platforms, including Windows, Linux, Android, Hongmeng, and Kylin, among others.
Features

2. Supports PLC remote real-time monitoring and management of the power system.
3. Available for manual, PLC remote, timed automatic operation, and power-off control.
4. Standard with overcurrent and short-circuit protection.
5. Different color indicator lights differentiate the phase line power input status.
6. Manual, Stop, and Automatic - Three-position panel control toggle switch.
7. All critical components are made with internationally renowned brand electronic components; cables are all selected as national standard copper cables, with all cables utilizing copper terminals for crimping. The wire diameters inside the box are equipped with over 20% safety margin.
8. Select power-on state after power failure to ensure stable operation of the equipment upon power restoration.
9. Standard features include circuit status monitoring, current and voltage detection, overload protection, under-voltage and under-current protection, intrusion protection, smoke protection, electrical cabinet over-temperature protection, LED screen over-temperature protection, and联动 protection with multiple safety functions.
10. Multi-channel step-by-step automatic sequential power-on delay.
11. Supports 8 groups of scheduled tasks for automatic control and management.
12. Products are designed and manufactured in accordance with national standards, featuring unique reinforcement in the shell design and using sheet metal with a thickness of 1.2mm or more, then powder-coated.
13. The entire system is pre-set with various contingency plans. When used online, it allows for remote monitoring of the power cabinet's status. In offline mode, it can automatically execute the logic of contingency plan联动.
14. Standardly equipped with circuit breakers for overcurrent protection and a lighting control circuit.
15. The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kirin, and more operating systems.
