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. Due to the large number of switching power supplies feeding LED screens, 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 housing, with a total load power of 90KW, capable of connecting 27 single-phase electrical equipment lines (such as display circuit, air conditioning circuit, fan circuit); it offers multiple protections like overcurrent and short-circuit protection. It can manually shut off power, turn on via PLC, and turn off power. The standard circuit breaker is from DELIXI, while the contactors are from Schneider Electric. The PLC power supply uses Mingwei's high-reliability industrial-grade products, and the controller employs Omron/IPMS/Siemens PLC products. It has RS232/TCP/IP communication capabilities, allowing connection to a central control system for integrated control; it also features interfaces for smoke, temperature, and other sensors. It provides quick and convenient external data monitoring for LED display systems, enabling alarms for cabinet and LED screen over-temperature, smoke, intrusion, etc., through preset schemes. It can automatically and intelligently protect and control via set thresholds, achieving unattended operation. The system employs a B/S architecture and is compatible with multiple platforms, including Windows, Linux, Android, Hongmeng, Kylin, and more operating systems.
Key Features
1.All models feature dual 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, timer automatic control, power off available.
4.Standard with overcurrent and short-circuit protection.
5.Different colored indicator lights differentiate the phase wiring power condition.
6.Manual, Stop, Automatic, three-position panel control switch.
7.All key components are made with internationally renowned brand electronic components; all cables are selected with national standard copper cables, and all cables are terminated with purple copper terminals. The wire diameters inside the box have a safety margin of over 20%.
8.Select power-on state after power outage to ensure stable operation of the equipment upon power restoration.
9.Standard with circuit status detection, current and voltage detection, overload protection, under-voltage and under-current protection, intrusion protection, smoke protection, electrical cabinet over-temperature protection, LED screen over-temperature protection, and联动 protection with multiple 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 are made from sheet metal with a thickness of 1.2mm or more, electroplated with paint.
13. All systems are pre-set with various plans. When used online, remote monitoring of the power cabinet's status is available. In offline mode, the plans can automatically trigger logical联动.
14．Standard equipment includes circuit breakers with leakage protection and lighting control circuits.
15.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, and Kylin, among other operating systems.
