POE Ethernet surge protector
1. Overview
The surge protector device designs according to the national standard of GB/T18802.21-2004/IEC61643-21:2000
2.Functions Characteristics
Composite lightning surge protection for data lines and power supply equipment in line Power over Ethernet, the internal structure includes two protection schemes for data and power cables, to ensure precise system over-voltage protection, free by induction over-voltage, operating voltage and electrostatic discharge damage; at the same time with different voltage levels of signal power of lightning protection. The entire product features: multi-level protection, flow capacity, low voltage limit, fast response time, low insertion loss, higher transfer rate.
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.
