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
