The LED display is powered by a large number of switching power supplies and has a capacitive load. When the screen is started, the instantaneous current is extremely large, which is easy to form an impact on the power grid and cause damage to the electrical equipment. Therefore, the display with a power exceeding 20KW should be equipped with a belt distribution Power distribution cabinet with step-by-step power-on function.

　　 The current LED display screens are often more than ten square meters, and the larger ones are dozens of hundreds of square meters, and the power of the whole screen is relatively large. For such high-power electrical appliances, there is no room for sloppy safety in use, and major safety accidents such as short-circuits, screen burns, and fires may occur at any time due to lightning strikes and overloads. If millions of LED displays fail just because of a small power distribution cabinet problem, it is really a small loss. Moreover, some customers find electricians in the market to customize power distribution cabinets according to power consumption. During the customization process, it is necessary to find a professional electrician to communicate technical matters face-to-face, for fear that omissions will cause installation troubles and waste a lot of time and energy.

　The role of the LED display power distribution cabinet is to control the distribution of electrical energy to various load positions, and to protect the power when the circuit is short-circuited, overloaded and leaked. It mainly supplies power to the LED screen. It supports AC380V power input, air switch protection, and 220V power output. The chassis adopts a special design to prevent the possibility of leakage, and it is safer to use. It has a power indicator light.
