How to wire the LED display?
Friends who have participated in the assembly and installation of LED display know that behind the beautiful and flat LED display, it is the corresponding wires, network cables, signal cables, etc. intertwined together, which are jointly connected to show the beautiful pattern on the front of the LED display.
In the previous article we explored how to choose the module power cord for LED display. In this article, we will explain in detail how to wire the wires of LED display.
The first step, according to the working current to choose the cross-section of the wire (thickness)
In the previous article, we talked about how to choose the module power cord (5V operating environment). Then how to choose the wire between the power supply and the power supply (220V operating environment)?
Also according to national standards, we use the conventional LED display power supply for 200W or 300W, the input side current is generally 20-25A, so we connect the power supply and power supply of the main wire is generally used 2.5mm² copper wire.
Special circumstances, installation space limitations, or LED display current and power is larger, such as we use high-power 400W LED display power supply, the output side of the loaded P10 outdoor 2S module, the current load is larger (for example, 10A), our full-color one tow two power cord can choose to use 1.5mm ² copper wire to do the front section, 2.5mm ² copper wire to do the rear section, the power supply input side ( 220V) current is about 25-30A, we use 4mm² copper cable.
The second step, the conventional wiring sequence
Conventional LED display power supply we use is 200W or 300W, in the 5V (or 4.5V) end of the module power supply cable
to the module power supply block. Power input (220V) wire access order: red (fire or phase) to the “L” terminal, blue (zero or neutral) to the “N” terminal, yellow (ground) to the “ground” terminal. “terminal.
The third step, the large screen wiring and wiring
According to the national standard conversion, we know that 2.5mm ² copper wire loaded power for 5KW, then the corresponding is within 25 200W power supply or 16 300W power supply connected all the way to the 2.5mm ² cable out, and each power supply corresponds to the corresponding number of modules and the display area, according to the principle of calculating, we will be able to know how much power should be loaded on the distribution cabinet of the large screen, the main feeder cable should be used. How much cross-section of the cable should be used for the main feeder.
For example, P8 outdoor display, 80 modules wide (20.48 meters wide), 120 modules high (15.36 meters high), a total of 1,600 200W power supply, then the maximum power of the display is 320KW, in accordance with the above principles, the power distribution cabinet should be equipped with 64 road 2.5mm² copper cable out. Other air conditioning refrigeration and exhaust system with electricity calculated separately, in other articles we explain.
