LEDIn the display screen industry, the distribution cabinet, as one of the core components, directly impacts the stability and lifespan of the display screens due to its performance and reliability. Since LED screens are powered by a large number of switching power supplies, the initial start-up current is high, which can easily create a shock to the power grid. Therefore, for display screens with a power rating over 10KW, a dedicated intelligent distribution cabinet for LED screens should be provided.
This product features an indoor housing with a total load power of 120KW, capable of connecting 36 single-phase power-consuming devices (such as display circuit, air conditioning circuit, and fan circuit). It offers multiple protections like overcurrent and short-circuit protection, and can be manually shut off or powered on using PLC, with a power-off function. The standard circuit breaker is a Delixi product, and the contactor is a Schneider product. The PLC power supply uses high-reliability industrial-grade products from Mervic, and the controller employs Omron/IPMS/Siemens PLC products. It is equipped with RS232/TCP/IP communication capabilities, allowing for integration into a central control system for联动 control; and comes with ports for smoke, temperature, and other sensors. It provides quick and convenient external data monitoring for LED display systems, and can trigger alarms for cabinet, LED screen overtemperature, smoke, and intrusion alarms through predefined schemes. It can automatically and intelligently control protection through setting thresholds, enabling unattended operation. The system adopts a B/S architecture and is compatible with multiple platforms, including Windows, Linux, Android, Hongmeng, and others.
Feature Highlights
1.All models feature dual protection; input circuit breakers are chosen as molded-case circuit breakers, while output circuit breakers are selected as miniature circuit breakers.
2. Supports PLC remote real-time monitoring and management of power systems.
3.Manual, PLC remote, timer-controlled on/off, power failure protection.
4.Standard with overcurrent and short-circuit protection.
5.Different color indicator lights differentiate the phase line power supply status.
6.Manual, Stop, Automatic, three-position panel control switch.
7.All critical components are manufactured using internationally renowned brand components; all cables are selected with national standard copper cables, and all cables are terminated with brass terminals, with each cable having a 20% or more safety margin in the box.
8.Select power status after power outage, to ensure stable operation of the equipment upon power restoration.
9.Standard with circuit status detection, current and voltage monitoring, 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, among other safety features.
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 housing design and using sheet metal with a thickness of 1.2mm or more, coated with plastic.
13. All systems are pre-set with various contingency plans. When used online, they allow for remote monitoring of the power cabinet's status. In offline mode, they can automatically execute the contingency 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 and supports Windows, Linux, Android, HarmonyOS, Kirin, and more operating systems.
