2.7.4 Maximum power consumption: 1300w/㎡

2.7.5 Power distribution system and its functions

1) All hardware equipment must comply with the relevant national standards and standards for electronics majors. See the attachment for the standards.

2) The power distribution box is controlled by the programmable logic controller, and the power load is put into the power grid step by step to reduce the current impact of the screen system on the power supply network.

3) The distribution box is equipped with protection devices such as overcurrent, short circuit, open circuit, overvoltage, undervoltage, and temperature, and at the same time, necessary indicating devices are added to facilitate the maintenance of faults.

4) The resistance of the protective ground wire to the earth is less than 4 ohms, and a three-phase five-wire system is required for power supply. In addition, it is necessary to use a signal ground independent of the protective ground for the use of the network system and the distributed control system.
