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-skærm er et elektronisk produkt, og en af de største nemesis af elektroniske produkter er vand, men det er vores opgave at installere det i det fri, så vi skal være særligt opmærksomme på dets vandtætte foranstaltninger. Først og fremmest kan en god tætningsinstallation effektivt mindske risikoen for, at vand trænger ind i displayskærmen. Med hensyn til de originale dele kan vi gøre et godt stykke arbejde med anti-korrosion. For eksempel er overfladen af printpladen belagt med tre-fast maling; bagsiden er belagt med et vandtæt lag, men du skal være opmærksom. , Den lille strimmel på bagsiden angiver den vandtætte ydeevne af skærmens aluminium-plastikpanel. Husk at bruge en elektrisk boremaskine til at designe et vandudtag under aluminiums-plastikpanelet; vælg et stort-navn og høj-kvalitetsproducent til strømstikket og ledningsbøtten.
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.
