In the LED display industry, the distribution box, as one of the core components, directly affects the stability and lifespan of the display due to the high startup current of the screen powered by numerous switch-mode power supplies. It's prone to impact the power grid. Therefore, for displays with power exceeding 10KW, a dedicated intelligent distribution box for LED displays should be provided.

This product features an indoor housing with a total load power of 10KW, capable of connecting 3 single-phase electrical equipment lines (such as display circuit, air conditioning circuit, and fan circuit). It offers overcurrent and short-circuit protection, and can perform manual power on/off and PLC power on/off functions. It is equipped with RS232/TCP/IP communication, allowing for integration with central control systems for联动 control. It assists in quickly and conveniently monitoring external data of LED display systems and remotely controlling the intelligent power supply. The system, based on the B/S architecture, is cross-platform compatible with Windows, Linux, Android, HarmonyOS, and more operating systems.
Feature highlights
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 the power system.
3.Manual, PLC remote control, and power-off options available.
4.Standard with overcurrent and short-circuit protection
6.Manual, Stop, Automatic – three-position panel switch control.
7.All critical components are made with renowned brand electronic components; all cables are selected with national standard copper cables, and all cables are terminated with purple copper terminals. The cable diameters inside the box are equipped with over 20% safety margin.
8. Multi-channel automatic step-by-step sequential power-on delay.
9. Products are designed and manufactured in accordance with national standards, featuring unique reinforcement in the shell design and made of sheet metal with a thickness of 1.2mm or more, electroplated with paint.
10. All systems are pre-set with various contingency plans. When used online, they allow for remote monitoring of the power cabinet's status. In offline mode, they can automatically execute the plans according to their logical sequence.
11.All models come standard with a test socket equipped with leakage protection.
12.The system is cross-platform compatible, supporting Windows, Linux, Android, HarmonyOS, and more operating systems.
