Low AC/DC Power 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 low-voltage AC,DC power system surge protection. Protect them from the over-Voltage, over-Currency, electrostatic discharge etc.; The main traits as follows:Multi-level protection, width capacity, low limit-voltage, fast response time, Low insertion loss, high speed and so on;
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.
