Video, Power & Controller 3 IN 1 SPD
1. Overview
The surge protector device designs according to the national standard of GB/T18802.21-2004/IEC61643-21:2000
2. Function characteristics
Application in the power, control signals, video signals protection special for the CCTV system, Video switcher over-Voltage, over-Currency, electrostatic discharge damaged; the device possesses the futures as follows: Multi-level over-voltage protection, Integrate function, width capacity, low limit-voltage, fast response , Low insertion loss, high speed etc.
3. Usage Environment
Temperature:-40ºC~70ºC;Relative humidity:≤95%;Atmospheric pressure:70kPa~106 KPa.
4. Working Principle
Surge protector link with the equipment which be protected in the front of the system. When transmission lines were happen to the lightning and other instantaneous overvoltage shocked, the impulse current through the surge protector grounding cables discharging into the earth, and limit output the voltage with the device allow -voltage. Ensure the safety of the equipment.
