Outdoor LED electronic screen is now almost everywhere in daily life. Most of the LED screen is used as the electronic heart. Power supply plays an important role in the stability and safe operation of LED electronic screen. Therefore, in the dog days and thunderstorm weather season, appropriate safety and maintenance are needed.
1. Lightning protection measures of various measures
Ensure that the power supply is well grounded, and the display device uses the shared grounding structure, that is, “three positions” (equipment operation grounding, power grounding, lightning protection grounding) are configured as one.
When using our products in the strong lightning area or the building site where the lightning protection measures are not standardized, please set the lightning protection facilities at the input side. Or we can contact our customer staff. We will provide you with a comprehensive lightning protection program.
2. Prevent the working environment temperature from being too high
The internal space is sealed, and the air is not convective (it is recommended to install louvers and rainproof windows, with air intake below and air exhaust above).
When selecting power supply, it is recommended to reserve 20% power supply surplus to prevent the power supply from overheating and damaging the power supply during operation.
3. Thunderstorm prone seasons control the humidity of the working area of the display screen
In order to maintain the environmental humidity of the LED electronic screen or the area where the system belongs, please do not let anything with moisture characteristics enter the LED large screen curtain wall or the area where the system belongs.
If it is used in wet area or rainy season, and the product can not work normally for 24 hours, in order to ensure the safety of the system, please contact the customer service representative. Dell provides three kinds of processing power products: moisture-proof, mildew proof and fog proof.
4. Overload (current) damage and high input voltage
LED large screen can avoid playing for a long time on full bright screen (such as all white, all red, all green and all blue), and avoid the influence of excessive load current and power supply overheating on power supply life. Keep the power supply stable, prepare for grounding and prevent lightning strike. Do not use it in harsh natural conditions, especially in strong lightning weather.
It is recommended to use LED electronic screen at least once a week. Usually, the screen or system is turned on at least once a month, and it is lit for more than 2 hours.
5. Active protection
Avoid possible problems, actively protect and keep away from things that may cause harm to the power supply. Moreover, when cleaning the LED screen or system, it is necessary to wipe it gently to prevent water and minimize the possibility of injury.
