Description
ST-SPV301/220V is a video 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.
