How to calculate the quantity of Power Supplier of an Outdoor LED Screen?


How to calculate the quantity of Power Supplier of an Outdoor LED Screen?


The quantity of Power Supplier of an Outdoor LED Screen is a difficult mathematical calculation problem.

How to calculate the quantity of Power Supplier of an Outdoor LED Screen?


Firstly, The LED display requires a 5V power supply. There are two kinds of LED Display Screen Power supply: 5V 40A and 5V 60A.


Secondly, The working efficiency of LED Display Screen Power supply is maximum 80%. That is to say the actual power wattage are 160W and 240W.


Thirdly, The currency of the led module is the data that can be obtained during the production process. 


Generally speaking,

  1. The electric currency of 1/10 scan P4 Outdoor LED Module(320mm*160mm) is around 8.5A;

  2. The electric currency of 1/8 scan P5 Outdoor LED Module(320mm*160mm) is around 5.5A;

  3. The electric currency of 1/5 scan P8 Outdoor LED Module(320mm*160mm) is around 8 A.

  4. The electric currency of 1/2 scan P10 Outdoor LED Module(320mm*160mm) is around 8.5 A.

  5. The electric currency of 1/4 scan P10 Outdoor LED Module(320mm*160mm) is around 5.5 A.

  6. The electric currency of 1/8 scan P6 Outdoor LED Module(192mm*192mm) is around 5.5 A.

  7. The electric currency of 1/4 scan P8 Outdoor LED Module(256mm*128mm) is around 5.5 A.


If we do the mathematical calculation, we will know how to calculate the quantity of Power Supplier of an Outdoor LED Screen.


As a result the quantity of power supplier of LED module for Outdoor LED Screen:


1. 4 pcs of 1/10 scan P4 Outdoor LED Module(320mm*160mm)  need 1 pc of 5V 40A power supplier.

2. 6 pcs of 1/8 scan P5 Outdoor LED Module(320mm*160mm)  need 1 pc of 5V 40A power supplier.

3. 4 pcs of 1/5 scan P8 Outdoor LED Module(320mm*160mm) need 1 pc of 5V 40A power supplier.

4. 4 pcs of 1/2 scan P10 Outdoor LED Module(320mm*160mm)  need 1 pc of 5V 40A power supplier.

5. 6 pcs of 1/4 scan P10 Outdoor LED Module(320mm*160mm) need 1 pc of 5V 40A power supplier.

6. 6 pcs of 1/8 scan P6 Outdoor LED Module(192mm*192mm) need 1 pc of 5V 40A power supplier.

7. 6 pcs of 1/4 scan P8 Outdoor LED Module(256mm*128mm) need 1 pc of 5V 40A power supplier.
