PoE Surge Protector

PoE Surge Protector

The KSP48-401/KSP48-801 is mainly used for lightning protection in video surveillance systems, safeguarding the f PoE equipment from the impact of lightning electromagnetic pulses, induced overvoltages, and operational overvoltages. This PoE Surge protector employs multi-level protection circuits and high-speed protection components to achieve rapid response, precise protection, extremely low residual voltage, and minimal insertion loss. It can effectively ensure the safe operation of the system and prevent damage to system equipment or communication disruptions caused by overvoltage and overcurrent.
