Video monitoring SPD 1 multi-function surge protection 2 certificated by ISO9001:2008 3 3-in-1 design 4 insert loss low
NKP video SPD/ CCTV Surge Arrester
Product Description
NKP series video SPD is applied to the lightning surge protection of camera monitoring system front-end, power cord, video line, signal line. It can effectively prevent the equipment which is caused by potential difference of power and network line transient enlargement. It is designed with advantage of large intake capacity, low residual voltage, fast response time and long lifetime.

Product installation:
1, This product is in series installed on power cable, signal line and video line of the camera, the output end is connected with video camera, and it is better to keep away from the camera less than 50cm during installation.
2, The power supply connection: Products should be match with protected camera power supply voltage. When it needs installation please according diagram to install. One of power supply line, “L ~” is firewire or positive. “N ~” is zero line or negative.
3, The video signal connections: The input end is connected with the signal channel, output end is connected to the video camera, connectors should be connected securely and not be reversed.
4, The control signal connections: Each group use a pair of signal lines, then connect terminals whose logo is “CONTROL”.
5, Apply to indoor operation, such as outdoors installation. You must install waterproof shell.
6, All wiring must be solid and connect by electric. SPD cable: BVR≥1.5 mm2 , grounding wire: BVR ≥2.5 mm2 .
7, Lightningproof grounding should be consistent with lightning protection regulatory requirement, ground wire should be thick and short as possible, resistance should be less than 10Ω.
