Description
ST-SV308 is a 8-ch video surge protector device designed according to the standard of GB/T18802.21-2004/IEC61643-21:200. The device’s nominal operating voltage is 5V, max continuous operating voltage is 6V, limiting voltage lower than 20V. It features multi-level protection、high capacity for through-flow、low limiting voltage、quick reaction time、less insertion loss. It adapts to overvoltage protection for security video signal and power, protecting the device from the damage of induced overvoltage, switching overvoltage and static discharge. It’s widely used in security monitoring system, environment monitoring system.
