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 displays 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 displays with power over 10KW, it is necessary to equip with a dedicated intelligent power distribution cabinet for LED displays.
This product features an indoor shell, with a total load power of 50KW, capable of connecting 15 single-phase power equipment (such as display circuit, air conditioning circuit, and fan circuit). It offers multiple protections including overcurrent and short-circuit protection, and supports manual power on/off and PLC-powered operation. The standard circuit breaker is a Delixi product, while the contactor is from Schneider Electric. The PLC power supply uses Mingwei's high-reliability industrial-grade products, with controllers from Omron, IPMS, and Siemens PLCs. It is equipped with RS232 and TCP/IP communication capabilities, allowing integration with central control systems for centralized control. It also comes with interfaces for smoke, temperature, and other sensors. It provides quick and convenient external data monitoring for LED display systems, and can initiate alarms for cabinet overtemperature, smoke, intrusion, etc., through preset schemes. The system features an automatic and intelligent protection control with threshold settings, enabling unattended operation. The system is built using the B/S architecture and is compatible across multiple platforms, including Windows, Linux, Android, Hongmeng, and Qilin, etc.
Features and Benefits
1.All models feature two-level protection; the input circuit breaker is a plastic 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.
4.Standard with overcurrent and short-circuit protection.
5.Different color indicator lights differentiate the phase line power-in status.
6.Manual, stop, and automatic, three-position panel control switch.
7.All critical components are made with internationally renowned brand electronic components; all cables are selected with national standard copper cables, and all cables are crimped with pure copper terminals. The wire diameters inside the box have over 20% safety margin.
8.Select power status after power outage, ensuring 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 various protective functions.
10. Multi-channel step-by-step automatic sequential power-on delay.
11.Supports automatic control and management of 8 scheduling task groups.
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, then powder-coated.
13. All systems are pre-set with various contingency plans. When used online, they allow for remote monitoring of the power cabinet's status, and when used offline, they can automatically execute the contingency plan logic in联动.
14．Standard equipment includes circuit outlets with leakage protection and lighting control circuits.
15.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kirin, and more operating systems.
