Outdoor LED electronic display screen can be seen in daily life. The vast majority of LED electronic displays are used outdoors. They are used as cardiovascular devices for LED electronic displays. Switching power supply plays a particularly important role in the actual operation of the reliability and safety of LED electronic display screen. Therefore, in dog days and thunderstorms, appropriate safety and maintenance must be carried out. [LED power supply]
1. Lightning protection measures with multiple measures simultaneously refer to the use, that is, three positions (equipment operation grounding, power grounding, lightning protection grounding) are configured as one.
When the commodity is applied on the spot in the super strong lightning area or in the building where the lightning protection countermeasures are not standardized, please set the lightning protection equipment at the input side.
2. Avoid high operating temperature during operation
The internal space is sealed, and the air is not convective (it is recommended to install louvers, with air inlet below and air exhaust above).
When selecting the power supply, it is recommended to reserve 20% power margin to prevent the power supply from overheating and damaging the power supply during operation.
3. Ambient humidity in the working area of the operation display in the storm prone season
In order to better maintain the relative humidity of the air in the area where the LED electronic display screen or system software belongs, please do not let anything with moisture characteristics enter the area where the LED large screen building curtain wall or system software belongs.
When used in wet areas or rainy seasons, the product cannot work normally for 24 hours. To ensure system safety, please contact customer service. 4. Overload (current) damage, input voltage too high.
The LED large screen can avoid playing on the full bright screen (such as all white, all red, all green and all blue) for a long time, avoid the impact of power supply life caused by overload current and power overheating, keep the power supply stable, prepare for grounding, lightning protection, and do not use it under adverse natural conditions, especially in strong lightning weather.
It is proposed to apply LED electronic display screen at least once a week. Generally, open the screen or system software at least once a month and light it for more than 2 hours.
5. Proactive maintenance
Avoid possible problems, actively protect and keep away from things that may cause harm to the power supply. In addition, when cleaning the LED screen or system, wipe it gently as much as possible to prevent water and minimize the possibility of injury. [LED power supply]
The power supply should be placed in an environment with as little dust as possible. Excessive dust may damage the circuit. If water flows in due to various reasons, please turn off the power immediately and contact the service department. Water, iron powder and other conductive metals shall not flow into the power work site.
