LEDIn the display screen industry, the power distribution cabinet, as one of the core components, directly impacts the stability and lifespan of the display screens. Since LED screens are powered by a large number of switching power supplies, the screen's startup瞬间 carries a high current, which can easily create a surge in the power grid. Therefore, for screens with power exceeding 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 70KW, capable of connecting 21 single-phase electrical equipment (such as display circuit, air conditioning circuit, fan circuit); it offers multiple protections including overcurrent and short-circuit protection. It supports manual power-up, PLC power-up, and shutdown functions. The standard circuit breaker is a Delixi product, while the contactor is from Schneider Electric. PLC power supply uses high-reliability industrial-grade products from Mingwei. The controller employs Omron/IPMS/Siemens PLC products. It is equipped with RS232/TCP/IP communication, allowing connection to central control systems for integrated control; and features ports for smoke, temperature, and other sensors. It enables quick and convenient external data monitoring of LED display systems, and can initiate alarms for cabinet, LED display over-temperature, smoke, and intrusion via pre-set programs. It can automatically and intelligently protect and control with threshold settings, enabling unattended operation. The system is based on the B/S architecture and is compatible with multiple platforms, including Windows, Linux, Android, Hongmeng, Kirin, and more operating systems.
