Correct use of three-in-one lightning protector to avoid lightning surge of monitoring equipment
The three-in-one lightning protector can protect the camera of the surveillance camera from surge protection, so as to avoid damage caused by excessive voltage and electrostatic discharge. Applicable to various airports, buildings, military bases and other public places.
working principle:
With a low-voltage open state shows a high resistance, low-resistance short-circuit state appears high voltage, can withstand hundreds of amperes of high-current over-voltage protection over the combination of electronic devices used in power supply lines, signal transmission lines. When it encounters a lightning strike and a high voltage and high current, it immediately presents a short circuit, and at the same time, the main power switch is disconnected, so that the computer equipment is protected. The tandem installation uses only its physical surface form. The signal lightning protector requires that the loss of the high frequency signal be small.
Instructions:
1. Please look for the interface and connection method;
2, look for lightning protection device input / output interface identification, input and outside lines, output devices;
3. The stress of the grounding wire should be short, thick and straight to reduce the impact of the distributed inductance on the discharge of the electromagnetic pulse of the lightning strike;
4. Grounding of the signal lightning protector should be connected to the ground network through the electronic switch.
AJ3 series monitoring three-in-one lightning protection device is mainly used for monitoring system to monitor equipment (power line, PTZ control line, video line) protection; widely used in bank monitoring systems, community security system; schools, businesses, road safety protection And other monitoring equipment.
