The role of the LED display power distribution cabinet is to control the distribution of electrical energy to various load positions, and to perform power-off protection when the circuit is short-circuited, overloaded and leaked. It mainly supplies power to the LED display. 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. A good LED power distribution cabinet should have the following characteristics:

1. Operability: simple operation and convenient installation; the inlet and outlet joints are reserved, and the on-site construction is quick and convenient, saving on-site construction time.

2. Reliability: The main equipment inside the product adopts well-known brands with reliable performance, which is a strong guarantee for reliable power supply of the display; the selection of materials and materials are in accordance with the relevant standards for electrical power distribution.

3. Professionalism: The products are designed and manufactured completely in accordance with national and industry standards, with beautiful craftsmanship, safety and reliability, and greatly improved the grade of the supporting equipment.

4. Various control methods: The product has manual on-site control, and adopts multi-function cards to realize remote control and timing control.

V. Safety: The internal design of the product is equipped with lightning protection devices, which solves the problem of interference caused by lightning when the power supply equipment is outdoors.

Sixth, economy: the design fully considers the economy of on-site construction and wiring, and uses electrical materials appropriately and effectively.

7. Serviceability: The specifications of LED display screens are changeable, and the needs of power distribution cabinets are also different. They are designed and manufactured according to the requirements of the project customers. Professional engineers design the most suitable power distribution settings according to the specific project characteristics to effectively improve the project. Overall efficiency.

LED display is a high-power electronic device, and good power distribution equipment is one of the important conditions for the system to achieve reliable operation. 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 very large, which is easy to form an impact on the grid and cause damage to the electrical equipment. Therefore, the LED display with a power exceeding 20KW should be equipped with a belt Distribution cabinet with step-by-step power-on function.

Summary: The quality of the LED display power distribution cabinet is related to the safety and stability of the product operation. It is very necessary to choose a good LED display power distribution cabinet.
