Overview of the surge protector according to the national standard GB / T18802.21-2004 / IEC61643-21: 2000 design. 2. Features for power, video signal as one of the video surveillance system signal and power overvoltage protection against over-voltage sensing it, and over-voltage damage caused by electrostatic discharge; multi-level protection, through flow capacity, limiting low voltage, fast response time, the insertion loss is small. 3. The use of ambient temperature: -40 ℃ ~ 70 ℃; Relative humidity: ≤95%; atm:. 70kPa ~ 106 KPa 4. surge protector works in series with the front-end equipment to be protected, when the transmission line was lightning and other transient over-voltage shock when, the impact of current through the surge protector to protect the branch to vent into the earth, and the output voltage clamp within the allowable voltage range of equipment to ensure the safe operation of the equipment. 5.
