When buying an LED display, the first thing to do is to calculate an aspect, and then you can buy the corresponding LED display after the calculation. LED display power supply is generally 5V. When connecting the board, as long as the positive and negative poles are good, there will be no problem. At the same time, be careful not to short-circuit the positive and negative poles. The power socket on the board is connected to 5V and GND. Note that the positive and negative poles cannot be reversed. The power supply only distinguishes between VCC (5V) and GND. YONGS LED display to introduce the calculation method of the number of LED display power supply.
1. The number of unit boards that one power supply can carry = the voltage of the power supply the current of the power supply/the number of horizontal pixels of the unit board/the number of vertical pixels of the unit board/0.1/2 For example: semi-outdoor P10: 5V40A power supply can be brought : 540/(32160.1/0.5)=7.8 Take the larger 8.
2. Calculate the number of power supplies required according to the total power of the screen = average total power / power of a power supply (power supply voltage power supply current) For example: a long screen uses 12 P10 modules, and high uses 3 P10 modules Total group: 36 modules, then the number of power supplies required = 32160.1360.5/5/40=4.6 whichever is larger (5 power supplies).
3. LED display power calculation method: The power formula is P=UIhello LED display power supply wiring method and load calculation LED display, power supply, wiring technical knowledge titter represents power, U represents voltage, I represents current, usually we use The power supply voltage is 5V, the power supply is 30A and 40A; the single color is 8 unit boards and 1 40A power supply, and the double color is 6 unit boards and 1 power supply; the power of the outdoor screen refers to the "Product Parameters" on the website, there are very clear.
