How Does The Wire Of LED Display Screen Connect?

Those who have participated in the assembly and installation of LED displays know that behind the beautiful and flat LED displays are the corresponding wires, network wires, signal wires, etc. interlaced together, the common connection shows the beautiful pattern on the front of the LED display screen. In this section, we will explain in detail how to wire the LED display.

 

First Step, according to the working current selection of wire cross-sectional area (thickness) . Also according to the national standard, we use the regular LED display power supply for 200W or 300W, input current is generally 20-25A, so we connect the power supply and power supply of the main wire is generally used 2.5 mm2 copper wire.

 

Under special circumstances, the installation space is limited, or LED display current and power is large, for example, we use high-power 400W LED display power, output with P10 Outdoor 2s module, the current load is larger (for example, 10A) , we can choose to use 1.5 mm2 copper wire as the front section, 2.5 mm2 copper wire as the back section, power supply input (220V) current has 25-30A, we use 4mm2 copper cable.

 

The second step is the normal wiring sequence. The conventional power supply for the LED display screen we use is 200W or 300W, 5v (or 4.5 V) at the end of the module power cable to the module power base. Power input (220V) wire access sequence: Red (firewire or phase wire) to"L" terminal, blue (zero or neutral wire) to"N" terminal, yellow (ground) to"Ground" terminal.

 

 

The third step, the large screen of the cable and wiring. According to the national standard conversion, we know that 2.5 mm2 copper wire with a load power of 5 kw, then the corresponding is less than 25200W power supply or 16300W power supply with a 2.5 mm2 cable out, and each power supply corresponds to a corresponding number of modules and display area, according to this principle of calculation, you can know how much power should be large screen distribution cabinet nuclear load, the main entrance line should adopt how much cross-sectional area of cable.
