The method for calculating the power of an electronic screen is as follows:
Multiply the power per square meter of screen by the total area. Firstly, determine the maximum power per square meter of display screen. For example, the maximum power per square meter for a P2.5 display screen is 500 watts. If the display area is 30 square meters, the maximum power is 15 kilowatts (500 watts x 30=15000 watts, or 15 kilowatts). Due to transmission losses, the actual power consumption must increase by 20%, resulting in a total required power of 18 kilowatts.
Multiply the power of the pulse power supply by the quantity. For example, a 30 square meter display with P2.5 specifications requires 98 200 watt switching power supplies. The total power consumption is 19.6 kilowatts (98 units x 200 watts=19600 watts, or 19.6 kilowatts).
Calculate using formula ": Power formula: P=UI, where P represents power, U represents voltage, and I represents current. LED displays typically use 5V voltage and 30 or 40A current. For example, a 9-square meter internal dual color electronic screen uses a 40A power supply and is designed with a maximum power of 2600W (13 power packs x 40A x 5V=2600W).
The factors that affect the power of electronic screens include display screen type (such as external and internal), dot pitch, and dot density,
LED quantity, scanning method, etc. D. Other matters Outdoor displays typically have higher power because they require stronger light and higher excitation current. For example, the dot pitch of an outdoor display screen is 10 millimeters, and the dot density is 10000 dots per square meter. Each point is composed of 3 LEDs: 1 red, 1 green, and 1 blue. The scanning method is 1/4 of the scanning. The power per square meter is approximately 750 watts.
The methods to reduce energy consumption of electronic screens include optimizing the design and configuration of displays. For example, selecting the correct point spacing and scanning method can significantly reduce power consumption. In addition, the use of efficient pulse power supplies and optimized circuits also allows for high efficiency
