Product Description
NKP series video SPD is used to protect power supply, video and data devices of AC/DC-powered surveillance cameras from surge damage caused by sudden increase of potential difference between different devices when there is induction lightning strike. It is designed with advantage of large intake capacity, low residual voltage, fast response time and long lifetime.
