Introduction to LED power supply!

As the heart of the LED display, the driving power supply can be said to be crucial to the stable and safe operation of the LED display. It should be protected and maintained in a timely manner during the rainy season. So how should the outdoor LED driving power be protected and maintained in the rainy season? What about maintenance? The following are some tips for the safety protection and maintenance of LED drive power supply in the rainy season. Let's learn about it together with the summary of the editor.

1. Multiple measures for lightning protection

Ensure that the power supply is well grounded, and the display device adopts a common ground wire structure, that is, the "three grounds" (equipment working ground, power ground, lightning protection ground) in one way.

Note: When using our products in the field of strong lightning strike areas or buildings with non-standard lightning protection measures, please install lightning protection facilities on the input side, or you can contact the customer service personnel of the screen factory to provide you with overall lightning protection in time plan.

2. Control humidity

To maintain the humidity of the use environment of the LED display screen or the area where the system belongs, do not let anything with moisture properties enter your LED screen or the area where the system belongs.

Note: When using in humid areas or rainy seasons, and the product is not working 24 hours a day, in order to ensure the safety of your system, please use three-proof power supply products (moisture-proof, mildew-proof, anti-fog).

3. Active protection

Try to avoid problems that may be encountered, take active protection, and try to keep items that may cause damage to the power supply away from the power supply; and when cleaning the LED screen or system, wipe it as gently as possible to make it waterproof and prevent possible damage. sex to a minimum.　

4. Control usage time

It is recommended to use the large LED screen at least once a week during the rainy season. Generally, turn on the screen or system at least once a month, and light it for more than 2 hours.

5. Water, iron powder and other conductive metal objects are strictly prohibited in the working area of ​​the power supply

The drive power supply should be placed in an environment with low dust as much as possible. Too much dust will cause damage to the circuit. If water enters for various reasons, please immediately cut off the power and contact the maintenance personnel.

Note: Do not force the boot to use!

6. Prevent the working environment temperature from being too high

 The space inside the LED display box is sealed, and the air is not convected (it is recommended to install a louvered rainproof window, and the lower air intake is upper exhaust).

Suggestion: When selecting a power supply, a 30% power margin should be reserved to prevent damage to the power supply caused by overheating during the working process.

7. Overload (current) damage and excessive input voltage damage

Do not stay in all white, all red, all green, all blue and other full bright screens for a long time during playback, so as not to cause excessive load current, excessive heat generation of the power supply, and affect the service life of the power supply. Keep the power supply stable, and do a good job of grounding protection to avoid lightning strikes. Do not use it under harsh natural conditions, especially strong lightning weather.
