Applications: 
 Combo SPD, for fixed cameras and coaxial cable transmission signal using a fixed camera, single-Optical devices such as lightning and surge protection. 
 Product Features: 
 SPD connected in series circuit, the product is multi-level design of lightning protection against over-voltage protection, lightning protection equipment in connection with the line sensor to mine electromagnetic pulse, surge voltage and electrostatic discharge, the SPD through timely and effective rapid response elements within the control circuit on the high voltage, high current, instant connection with the earth, will be sensitive to the pulse on the line voltage, current leakage into the ground (nanosecond response time), after the SPD to ensure terminal equipment from damage and interference, so that it can work, play the best effect. This product uses aluminum shielding package, with a small, easy installation, with instructions to work function, power supply voltage 220V, 24V, 12V optional. SPD to be grounded, grounding lightning protection should be consistent with regulatory requirements (grounding resistance should be less than 10Ω), and the ground wire as far as possible coarse, short, straight.
