Everyone knows about LED display screens, especially the big-name advertisements that are constantly playing in squares and commercial centers are very impressive. Today, let's talk about the precautions for its waterproof power supply.
LED display is an electronic product, and one of the biggest nemesis of electronic products is water, but it is our job to install it in the open air environment, so we need to pay special attention to its waterproof measures. First of all, a good sealing installation can effectively reduce the risk of water entering the display screen. For the original parts, we can do a good job of anti-corrosion. For example, the surface of the PCB board is coated with three-proof paint; the back is coated with a waterproof layer, but you need to pay attention. , The small strip on the back indicates the waterproof performance of the aluminum-plastic panel of the screen. Remember to use an electric drill to design a water outlet under the aluminum-plastic panel; choose a big-name and high-quality manufacturer for the power plug and wire bucket.
In the daily power supply process of the LED display, the rated voltage is about 220V, and the domestic voltage is relatively stable, and there will be no big deviation. But be careful not to reverse the positive and negative poles of the power supply terminals, if the wrong connection will cause the display screen to burn out or even fire. When installing, choose a place where there are no high-power electrical appliances around, and use the grounding method to prevent lightning damage and ensure safety and reliability. In the process of using the LED display, do not switch on and off continuously in a short period of time, and pay attention to supplying power to the display step by step when turning it on, so as not to affect the life. At the same time, pay attention to regular maintenance and repair. The circuit inside the display screen must be adjusted and tested by professionals, so as not to cause electric shock and circuit damage. If it is found that a short circuit trip occurs, do not carry out the power-on test all the time, but contact the relevant personnel for maintenance.
