Product features
1. with remote alarm dry contact, it is convenient for remote monitoring.
2. Equipped with lightning counter to record the number of lightning strokes accurately.
3. With the power status indicator, indicating the working state of the lightning protector.
Working principle of product
In the normal working condition, the lightning protection module is in the disconnected state and does not affect the normal work. When the line has the impulse overvoltage at the moment when the lightning strikes, the lightning arrester module quickly passes through the very short time, short the overvoltage to the earth, and when the pulse overvoltage disappears, the lightning arrester module is resumed to disconnect. State, which does not affect the power supply of the user.
Use of attention
1. all wiring must be firmly and reliably connected
2. lightning protection and grounding shall conform to the requirements of lightning protection specification. The grounding wire shall be as thick as possible, and the grounding resistance shall be less than 10 Europe.
3. ground wire is less than 1 meters
