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 screens are powered by a large number of switching power supplies, the screen body draws a high current at startup, which can easily impact the power grid. Therefore, for display screens with power over 10KW, a dedicated intelligent power distribution cabinet for LED screens should be installed.

This product features an indoor housing with a total load power of 40KW, capable of connecting 12 single-phase electrical equipment circuits (such as display circuit, air conditioning circuit, fan circuit). It offers multiple protections like overcurrent and short-circuit protection, and can manually switch on/off power, as well as control via PLC. Standard circuit breakers are from Delixi, and contactors from Schneider. PLC power supply uses Mingwei's high-reliability industrial-grade products, with controllers from Omron/IPMS/Siemens PLCs. It has RS232/TCP/IP communication capabilities, allowing for integration with central control systems for联动 control; and is equipped with interfaces for smoke, temperature, and other sensors. It enables quick and convenient external data monitoring of LED display systems, and can trigger alarms for cabinet, LED display over-temperature, smoke, and intrusion through pre-set programs. The system can automatically and intelligently protect and control via set thresholds, achieving unattended operation. The system adopts a B/S architecture, compatible with multiple platforms and operating systems including Windows, Linux, Android, Hongmeng, and Kirin, etc.
Key Features
1.All models feature two-stage 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 the power system.
3.Manual, PLC remote, timed automatic control, power failure.
4.Standard with overcurrent and short-circuit protection.
5.Different colored indicator lights differentiate the phase line power-on conditions.
6.Manual, stop, automatic, three-position panel control switch.
7.All critical components are made with internationally renowned brand components; all cables are selected with national standard copper cables, and all cables are terminated with purple copper terminals, with a 20% or more safety margin for wire diameters inside the box.
8.Select power state after power outage to ensure stable operation upon power restoration.
9.Standard features include circuit status detection, current and voltage monitoring, overload protection, under-voltage and under-current protection, intrusion protection, smoke protection, cabinet over-temperature protection, LED screen over-temperature protection, and联动 protection with multiple safety functions.
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 housing design and using sheet metal with a thickness of 1.2mm or more, which is then powder-coated.
13. All systems are pre-set with various contingency plans. When used online, remote monitoring of the power cabinet's status is available, and when used offline, automatic implementation of the contingency logic联动 is achieved.
14.Standard with circuit-breaker-protected test sockets and lighting control circuits.
15.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, Kirin, and other operating systems.
