Taxi advertising screen installation power line wiring method

There are many ways to connect the power cable when installing the LED display on the car. However, many customers will have a misunderstanding. It is directly connected to the battery or the cigarette lighter. In fact, this is wrong because the voltage of our taxi battery is on the road. Or when the battery is used for a long time, the voltage will be unstable. If the voltage is unstable, it will affect our advertising screen. If the light is not normal, the black screen will be heavy. The vehicle power supply has an over-current protection function lower than 9V or higher than 33V. The screen will automatically power off, but in order to better run our car led display, please follow the following
Method operation:
★ Wiring 1 screen must be connected to the back of the regulated processor (such as the speaker power supply) when connecting the power supply on the car. The best way is to connect a power switch to install near the driver. When the voltage is stable, turn on the switch button of the screen (because the starting voltage of the car is high or low, the power supply to the screen is not good), which can increase the service life of the screen.
★ Wiring 2 Screen power supply can also be connected to the insurance behind the thinking, it is best to draw a power switch according to the driver's hand before the start of the car after the start of the voltage is stable, then turn on the screen switch button and a light line to follow The car's light line goes all the way so that the night light can be automatically lit.
★ When the screen is connected to the power supply of the car, the middle wiring must be soldered, and it should be covered with insulating plastic. The wiring must be under the floor, not under the seat, so as not to move the seat. Broken caused a short circuit.
★ The screen and the fixed tripod must be tightened. It is best to add the spring washer to install the screen to be stable and not shaken! ! !
The above is the comprehensive opinion of my collection of many customers, if the customer has a better car screen wiring method welcome guidance!
