Applications: 
 Triple lightning, coaxial cable to transmit video signals and PTZ cameras, Optical devices for lightning and surge protection. 

 Product Features: 
 SPD connected in series in the line, multi-level mine protection against excessive design and induction into the mine electromagnetic pulse and lightning protection equipment connected to the line, the surge voltage and electrostatic discharge, lightning protection devices through internal timely and effective rapid response element of the control circuit of high voltage, high current, and instantly connected to the earth, the line sensor to pulse voltage, current drain into the ground (reaction time to nanoseconds) to ensure that the SPD end equipment from damage and interference, so that it can work, play the best role. This product uses aluminum shielding package, with a small, easy to install with the function of the normal work instructions, supply voltage 220V, 24V, 12V optional. SPD needs to be grounded, grounding should comply with the lightning regulatory requirements (grounding resistance should not be greater than 10Ω), and the ground line as far as possible coarse, short, straight.
