Now the application penetration rate of LED display has been very high. When purchasing LED display, there are many calculation formulas. Only when the calculation is correct, can the best LED display be selected. Such as spacing, length and height, number of modules used, etc. But many people don't know much about this. Today, YONGS LED display will tell you about his power calculation method.
Fòmil pou pouvwa a se P=UI.
P stands for power, U stands for voltage, and I stands for current. Usually, the power supply voltage we use is 5V, and the power supply is 30A and 40A; single color is 8 unit boards and 1 40A power supply, and two-color is 6 unit boards. 1 power supply; The power of the outdoor screen is very clear in the "product parameters" on the website.
Yo pral bay yon egzanp anba a:
Yon inite bezwen fè yon ekran elektwonik andedan kay la 5.0 de-koulè 9 mèt kare, epi kalkile pouvwa maksimòm ki nesesè. Premyèman, li trè senp pou kalkile kantite 40A pwovizyon kouran=9 (0.2440.488)/6=12.5=13 pwovizyon kouran (pou yon nonm antye, kèlkeswa sa ki pi gwo), pisans maksimòm P=1340A5V=2600W. Pouvwa yon sèl lanp=pouvwa yon sèl lanp 5V20mA=0.1W.
Pouvwa a nan tablo a inite ekspozisyon dirije=pouvwa a nan yon rezolisyon lanp sèl (kantite piksèl orizontal kantite piksèl vètikal) / 2.
Pouvwa maksimòm ekran an {{0}} rezolisyon ekran an kantite limyè pou chak rezolisyon 0.1.
Pouvwa mwayèn ekran an {{0}} rezolisyon ekran an kantite limyè pou chak rezolisyon 0.1/2.
Pouvwa aktyèl ekran an {{0}} rezolisyon ekran an kantite limyè pou chak rezolisyon 0.1 / kantite analiz (4 analiz, 2 analiz, 16 analiz, 8 analiz, estatik).
