Attention: During installation, if it needs to weld the grounding wire to the grounding grid, do welding job first and then connect the grounding wire with grounding terminal. Otherwise the power current caused by the welding will damage the SPD inside the product.
7. Application Scope
1) AC220V, AC24V, and AC12V power supply HD monitoring system digital camera.
2) Network transmission device system of RJ45 transmission rate.

Q1: Selection of surge protector
A: The grading of the surge protector (commonly known as lightning protection) Is assessed according to the IEC61024 subdivision lightning protection theory, which is installed at the junction of the partition.Technical requirements and functions differ. The first-stage lightning protection device is installed between the 0-1 zone, high for the flow requirement, the minimum requirement of GB50057 is 12.5 ka (10/350), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
