LEDIn the display screen industry, the power distribution cabinet, as one of the core components, directly impacts the stability and lifespan of the display screens. Since LED screens are powered by a large number of switching power supplies, the initial startup current is high, which can easily cause a surge in the power grid. Therefore, for screens with power exceeding 10KW, a dedicated intelligent power distribution cabinet for LED screens should be provided.

This product features an indoor shell, with a total load power of 140KW, capable of connecting 42 single-phase electrical devices (such as display circuit, air conditioning circuit, fan circuit). It offers multiple protections including overcurrent and short-circuit protection, and can manually switch on/off power, and control with PLC. Standard circuit breakers are from DELEK, and contactors from Schneider Electric. PLC power supply uses high-reliability industrial products from Mingwei. Controllers are from Omron/IPMS/Siemens PLCs. It is equipped with RS232/TCP/IP communication, allowing integration with central control systems for centralized control; it also features interfaces for smoke, temperature, and other sensors. It facilitates quick and convenient external data monitoring of LED display systems, and can trigger alarms for cabinet, LED screen over-temperature, smoke, and intrusion through pre-set programs. The system is designed with a B/S architecture, supporting cross-platform compatibility with Windows, Linux, Android, Hongmeng, and more operating systems.
Feature Highlights
1.All models feature dual 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 power systems.
3.Manual, PLC remote, timed automatic control on, power off available.
4.Standard with overcurrent and short-circuit protection.
5.Different color indicator lights differentiate the phase wire power input status.
6.Manual, Stop, Automatic - three-position panel control switch.
7.All critical components are made with internationally renowned brand electronic components; all cables are selected from national standard copper cables, and all cables are terminated with purple copper terminals. The cable diameters inside the box have more than 20% safety margin.
8.Select power state after power failure to ensure stable operation of the equipment upon power restoration.
9.Standard features include circuit status detection, 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 protection 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 made of sheet metal with a thickness of 1.2mm or more, coated with paint.
13. All systems are pre-set with various plans. When used online, they allow for remote monitoring of the cabinet's power status. When used offline, they can automatically execute the plan logic联动.
14.All models are equipped with test sockets with leakage protection and lighting control circuits.
15.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kirin, and more operating systems.
