LEDThe display screen industry relies heavily on power distribution cabinets as a core component, as their performance and reliability directly impact the stability and lifespan of the displays. Since LED screens are powered by a large number of switching power supplies, the startup surge of the screen body can easily create a shock to the power grid. Therefore, for displays with power over 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 100KW, capable of accommodating 30 single-phase power-consuming devices (such as display circuit, air conditioning circuit, and fan circuit). It provides multiple protections, including overcurrent and short circuit, and supports manual power on/off, PLC-powered on/off, and shutdown functions. The standard circuit breaker is a Delixi product, while the contactor is a Schneider product. The PLC power supply utilizes a Mingwei high-reliability industrial-grade product, and the controller is an Omron/IPMS/Siemens PLC product. It is equipped with RS232/TCP/IP communication capabilities, allowing for connection to central control systems for联动. It also includes smoke and temperature sensor interface ports. It facilitates rapid and convenient external data monitoring of LED display systems, and can initiate alarms for cabinet and LED display over-temperature, smoke, intrusion, etc., through predefined programs. It can also automatically and intelligently control protection via set thresholds, enabling unattended operation. The system adopts the B/S architecture and is compatible with multiple platforms, including Windows, Linux, Android, Hongmeng, and Kylin operating systems.
Features
1.All models feature dual protection; for input circuit breakers, we use plastic-case circuit breakers, and for output circuit breakers, we opt for miniature circuit breakers.
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 line power input status.
6.Manual, Stop, Automatic - three-position panel control switch.
7.All critical components are made with internationally renowned brand components; cables are all selected with national standard copper cables, and all cables are terminated with brass connectors, with each cable inside the box having over 20% safety margin.
8.Power-on state selection after power outage to ensure stable operation 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 linkage protection with multiple protective functions.
10. Multi-channel step-by-step automatic sequential power-on delay.
11.Supports 8 groups of scheduled task 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, coated with paint.
13. All systems are pre-set with various contingency plans. When used online, remote monitoring of the power cabinet's power status is available. In offline mode, the plans can automatically initiate logical联动.
14.All models are equipped with circuit breakers and lighting control circuits.
15.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kylin, and more operating systems.
