the power consumption of monochrome two color full color LED electronic large screen

How to calculate the power consumption of monochrome two color full color LED electronic large screen? Generally, the voltage of a module is 5V. As long as the current of the module is measured, the power of a module can be calculated, and then the power per square meter can be calculated according to the number of modules used per square meter. Generally, the current of the module tested by manufacturers is measured according to the maximum power, that is, when the module is white balanced. The power consumption of LED electronic large screen is introduced in detail by mini photoelectric LED display manufacturers.
1. Calculation of power consumption of P10 outdoor monochrome LED electronic large screen
1) Calculation method of power of P10 LED single red module
Assuming that the current of P10 outdoor single red module is 5.6A and the voltage is 5V, then the power of the module = current x voltage = 5.6ax5v = 28w.
2) Calculation method of whole screen power of P10 LED single red electronic large screen
The size of P10 outdoor single red module is 320x160mm, and the number of whole screen modules is about 19.5, then the power of whole screen = single module power x the number of whole screen modules = 28wx19.5 = 550W.
3) Calculation method of power consumption of P10 outdoor single red full screen
Generally speaking, the brightness and power of the module can reach the maximum value when playing white balance. However, we don’t play all white display (white balance) all the time in the process of using, so the power of the whole screen will be reduced, generally only 30-50% of the white balance power will be used. That is, the power per square meter is between 165W and 275W.
4) P10 detailed calculation method of outdoor single red full screen electricity charge
If the electricity charge is calculated as 1.5 yuan per kilowatt, the electricity charge of outdoor single red is 0.2475 yuan-0.4125 yuan per square meter per hour. If the size of the whole screen is 20 square meters, 10 hours a day, 365 days a year, then the annual electricity charge of the whole screen is: (0.2475w-0.4125w) * 20m2 * 10h * 365 days = 18067.5 yuan-30112.5 yuan.
2. Power consumption and tariff details of dual color outdoor LED electronic large screen
At the same time, the calculation method of power consumption and tariff details of dual color outdoor LED electronic large screen is the same as that of outdoor single red. Assuming that the power of P10 outdoor two-color module is 33W, the maximum power of the whole screen is 650W, and the actual use is 30% – 50%, that is, 195w-325w. The annual electricity charge of the whole screen is: (0.195kw-0.325kw) * 1.5 yuan * 20m2 * 10h * 365 days = 21352.5 yuan – 35587.5 yuan.
3. Power consumption and tariff details of outdoor full color LED electronic large screen
1) Calculation method of power consumption and electricity charge for conventional outdoor LED electronic large screen
The brightness of outdoor LED display screen is generally about 5500cd / m2-7500cd / m2. Generally speaking, the higher the brightness of LED display screen with the same configuration and model, the greater the power. So the maximum power consumption per square meter of the outdoor screen is about 700-1200w, and the power used for normal display of picture information is generally 280w-480w. If the whole screen is 100 square meters, the annual power consumption is 102200kw-175200kw, and the annual electricity charge is 153300 yuan-262800 yuan.
2) Calculation method of power consumption and electricity charge for outdoor energy saving LED display screen
The power consumption of outdoor energy-saving LED display screen is smaller than that of ordinary screen. The voltage of energy-saving module is generally about 3.8v-4.2v. Under the condition of constant current, the maximum power of the whole screen is about 480w-600w, and the power used for normal display screen is 192w-240w. If it is still calculated by 100 square meters, the annual power consumption of the whole screen is: 70080kw-87600kw, and the annual electricity charge is: 105120-131400 yuan.
Similarly, the calculation method of power consumption and tariff details of indoor monochrome and full-color LED displays is the same, which will not be introduced here. Customers can choose the LED display according to their own needs. Or in the purchase of products, ask the LED display manufacturers of the whole screen power consumption and peak power, in order to better wiring or whether to configure the distribution cabinet, with how much power distribution cabinet.
