Description
ST-SPVD301/24V is a video, control signal and power surge protector device designed according to the standard of GB/T18802.21-2004/IEC61643-21:200. The device 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.
