The power consume of the LED screen have the Average power consume and the Maximum power consume.

The Maximum power consume is the power consume when it’s starting or full lighting and the other extreme situations. The Maximum power consume is the necessary factor to consider when using the AC electricity power supply, the depth of the wire and the switch, too. Generally, the Average power consume is one out of three of the Maximum power consume. The LED display screen is the big size precision equipment. To operate in security and stability, the AV 220V power supply input port of the LED display screen or the connected computers’ power supply input port need to connect with the ground. Noted: computers’ power supply input port also must be connected with the body of the computer.
