How to wire the LED display?



The first step is to select the cross-sectional area (thickness) of the wire according to the working current. Also according to the national standard, the conventional LED display power supply we use is 200W or 300W, and the input current is generally 20-25A, so the main wire connecting the power supply and the power supply is generally 2.5mm ² Copper wire.


Under special circumstances, when the installation space is limited, or the current and power of LED display are large, for example, we use a high-power 400W LED display power supply, and the output end is loaded with P10 outdoor 2S module, and the current load is large (for example, 10A), we can choose to use 1.5mm full-color one-to-two power cable ² Copper wire as front section, 2.5mm ² The copper wire is used as the rear section, and the current at the power input end (220V) is about 25-30A, so we use 4mm ² Copper cable.


The second step is the conventional wiring sequence. Generally, the LED display power we use is 200W or 300W, and the module power line is terminated at 5V (or 4.5V) to the module power base. The power input terminal (220V) wire connection sequence is: red (live line or phase line) to “L” terminal, blue (neutral line or neutral line) to “N” terminal, and yellow (ground line) to “ground” terminal.

The third step is the branching and wiring of the large screen. According to the national standard conversion, we know 2.5mm ² The carrying power of copper wire is 5KW, so the corresponding power is less than 25 200W power supplies or 16 300W power supplies connected to a 2.5mm circuit ² The cables come out, and each power supply corresponds to a corresponding number of modules and display area. According to this principle, we can know how much power the distribution cabinet of the large screen should carry, and what cross-sectional area of cables should be used for the main incoming line
