In the LED display industry, the power distribution cabinet, as one of the core components, directly impacts the stability and lifespan of the display due to the high current surge during startup, caused by the large number of switching power supplies. Since this can create a significant impact on the power grid, it is essential to equip displays with a power rating over 10KW with a dedicated intelligent power distribution cabinet for LED displays.
This product features an indoor shell, with a total load power of 120KW, capable of connecting 36 single-phase electrical equipment lines (such as display loop, air conditioning loop, fan loop). It offers overcurrent and short-circuit protection, manual on/off power, and PLC-powered functions. The standard circuit breaker is a Delixi product, while the contactor is a Schneider product. The PLC power supply utilizes a high-reliability industrial-grade Mingwei product, and the controller employs Omron/IPMS/Siemens PLC products. It has RS232/TCP/IP communication capabilities, allowing for connection to a central control system for integrated control; it aids in rapid and convenient external data monitoring and remote intelligent power control of the LED display system. The system uses a B/S architecture and is compatible across multiple platforms, supporting Windows, Linux, Android, Hongmeng, and other operating systems.
Key Features
1.All models feature two-stage protection; the input circuit breaker is a molded case circuit breaker, and the output circuit breaker is a miniature circuit breaker. 2. Supports PLC remote real-time monitoring and management of the power system.
3.Manual, PLC remote, timed automatic control on, power-off
4.Standard with overcurrent and short-circuit protection
5.Different color indicator lights distinguish the phase power supply status.
6.Manual, Stop, Auto, three-position panel control switch.
7.All critical components are made with internationally renowned brand components; all cables are selected with national standard copper cables, and all cables are terminated with purple copper terminals, with a 20% or more safety margin for cable diameters inside the box.
8. Multi-channel step-by-step sequential power-on delay.
9. 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.
10. All systems are pre-set with various contingency plans. When used online, remote monitoring of the electrical cabinet's power status is available. In offline mode, the plans can automatically trigger logical联动.
11.Standard with circuit breakers and leakage protection in all inspection sockets and lighting control circuits.
12.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kylin, and more operating systems.
