LEDIn the display screen industry, as one of the core components, the performance and reliability of the power distribution cabinet directly affect the stability and lifespan of the display screens. Since LED display screens are powered by a large number of switching power supplies, the screen's startup瞬间 carries a high current, which can easily impact the power grid. Therefore, for display screens with power exceeding 10KW, a dedicated intelligent power distribution cabinet for LED screens should be installed.
This product features an indoor shell with a total load power of 80KW, capable of connecting 24 single-phase electrical equipment (such as display circuit, air conditioning circuit, fan circuit); it offers multiple protections like overcurrent and short-circuit protection. It can manually switch on/off power, and control power supply via PLC. The standard circuit breaker is a Delixi product, while the contactor is from Schneider. The PLC power supply uses high-reliability industrial-grade products from Mingwei. The controller is from Omron/IPMS/Siemens PLC products. It is equipped with RS232/TCP/IP communication, enabling connection to central control systems for联动 control; and features ports 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 display overtemperature, smoke, and intrusion through preset programs. The system can automatically and intelligently protect and control via set thresholds, achieving unattended operation. The system is built on the B/S architecture, compatible with multiple platforms and operating systems including Windows, Linux, Android, Hongmeng, Kirin, and more.
Key Features
1.All models feature two-level 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, 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, Auto, three-speed panel control toggle switch.
7.All key components are manufactured using internationally renowned brand components; all cables are selected from national standard copper cables, with all cables utilizing purple copper terminals for termination, and each cable inside the box has a safety margin of over 20%.
8.Select power state after power outage to ensure stable operation of the equipment upon power restoration.
9.Standard with circuit status detection, current/voltage monitoring, overload protection, under-voltage/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 delayed power-on.
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 utilizing sheet metal with a thickness of 1.2mm or more, then powder-coated.
13. All systems are pre-configured with various contingency plans. When used online, they allow for remote monitoring of electrical cabinet power status, and when used offline, they can automatically execute the logic of the contingency plan联动.
14All come standard with inspection sockets equipped with leakage protection and lighting control circuits.
15.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kirin, and more operating systems.
