In today's society, LED full-color electronic display applications are becoming more and more popular, and LED full-color electronic displays are used in almost all walks of life. When installing an LED full-color electronic display, you need to know about the power supply system. What power supply systems are required to install an LED full-color electronic display? Do you know? Let us introduce to you below.

   1. PLC control power supply system: For LED full-color electronic display screens with power consumption exceeding 10KW, power distribution cabinets should be equipped. Power distribution cabinets with remote control function or PLC control function can be selected according to needs. Power distribution cabinets with PLC control function are more intelligent, and the LCD controller can be used to remotely operate the LED display screen and the switches of the air conditioners, fans and other equipment in the screen. , to monitor the ambient temperature inside the screen, the fire situation, and the ambient brightness outside the screen in real time, and have corresponding alarm information. It is recommended that in the outdoor screen project, generally due to the poor environment, try to use the power distribution cabinet with PLC control; in the indoor screen project, the environment is better and the space is limited, so PLC control can be omitted.


   Second, long-distance communication: when the communication distance is within 1.2 kilometers, a pair of RS422/RS232 communication modules can be installed in the communication line; if the communication distance is several kilometers or even dozens of kilometers, optical fiber communication, PLC and computer should be used at this time. The communication modules at both ends should also be replaced with fiber optic RS232 converters.


   3. Power supply monitoring: In order to reduce the impact on the power grid when the high-power LED full-color electronic display is started, the power supply of the LED full-color electronic display is delayed in several steps, and the fault alarm status box on the PLC control interface has various The power-on status alarm indicator of the circuit power supply.


   Fourth, temperature monitoring: The LCD controller monitoring interface can display real-time temperature in the LED full-color electronic display. In the automatic state, when the temperature in the screen exceeds 65 degrees, the monitoring screen will prompt that the temperature is too high, and the LCD controller will sound an alarm, and the system will automatically power off to prevent fire.


   5. Fire monitoring: The LED full-color electronic display is also equipped with a number of smoke detectors. When there is a fire in the screen, there will be corresponding prompt information on the LCD controller monitoring interface, and the system will automatically power off.
