Aspects de la sélection de l'énergie de distribution de puissance d'écran LED?
Why do LED display products need a distribution cabinet? How to choose it? Below we will explain some knowledge about LED display distribution cabinet.
LED display is a high-power electronic equipment, good power distribution equipment is one of the important conditions for the system to achieve reliable work. LED display is powered by a large number of switching power supply, capacitive load, when the screen body starts, the instantaneous current is very large, easy to form an impact on the grid, causing damage to electrical equipment, so for the display with a power of more than 20KW, the distribution cabinet should be equipped with a gradual power-up function.The importance of distribution cabinets for LED displays
Now the LED display wall is a dozen square meters, large dozens of hundreds of square meters, the whole screen power is relatively large. For such a high power appliance in the use of safety is not easy, at any time may cause lightning strike, overload, short circuit, burning screen, fire and other major safety accidents. If only because of a small distribution cabinet problem caused millions of LED display failure is really due to small losses. And some customers look for electricians on the market, according to the power consumption to customize the distribution cabinet. In the customization process, to look for Professional electricians face-to-face communication of technical matters, afraid of leaks causing installation problems, wasting a lot of time and energy. The technical level of electricians is uneven, custom-made distribution cabinets will also hide a huge risk.
How to choose LED display distribution cabinet? Consider from the following angles:
Power consumption characteristics of the LED display – large impact current, light effective load; multi-segment partition power supply method;
Construction characteristics of LED display – multiple output lines, strong and weak electrical concentration, the design of the product is the result of years of LED display engineering practical experience, fully taking into account the results of LED display engineering practical experience, fully taking into account the construction characteristics of the LED display project, fully taking into account the special needs of actual engineering.
Operation: simple operation, easy installation; input and output connections are reserved, the site construction is quick and convenient, saving site construction time.
Fiabilité: the main equipment in the product is using well-known brands, reliable performance, is a strong guarantee of reliable power supply of the display; the selection of materials is according to the relevant standards of electrical distribution.
Professionalism: products are designed and manufactured in full accordance with national and industry standards, the process is beautiful, safe and reliable, greatly improving the quality of supporting equipment;
Une variété de méthodes de contrôle: the product has manual on-site control, the use of multi-function cards to achieve remote control, timing control.
Sécurité: The internal design of the product is equipped with lightning protection devices, which solves the problem of lightning interference encountered by power supply equipment outdoors;
Economics: the design takes full account of the economics of on-site construction and wiring, and uses electrical materials appropriately and effectively;
Service: LED display specifications vary, distribution cabinet needs are also different, according to the project customer requirements design and manufacture, by professional engineers according to the specific engineering characteristics, design the most suitable power distribution settings, to effectively improve the overall efficiency of the project.
