Features of the 10 Series CCTV Surge Protectors:
All Mode Protection
There are two ways that a transient can cause damage to electronic equipment. Firstly, a transient appearing between the inner conductor of a coaxial cable and its screen. Secondly, an overvoltage may appear between the cable’s screen and the terminal’s frame ground. Novaris LAN / video coaxial protectors provide protection for both potentially damaging overvoltages.
Each unit consists of multistage protection that incorporates a gas-filled surge arrester in combination with a fast transient suppression circuit between the line and coaxial screen. A low capacitance gas-filled surge arrester is connected between the cable screen and frame ground via a yellow/green flying lead for applications where the screen is not directly connected to ground.
Surge Current Fusing
Surge current fuses allow components to absorb maximum energy but in the event of a component failure the fuse will open to isolate the damaged component.
Safe Metal Enclosure
Novaris surge protection products are housed in safe, all metal enclosures. In the event of a prolonged overvoltage they will not catch fire or explode.
Let-Through Voltage Performance
As specified in the latest international standard on lightning protection for telecommunications, IEC61663-2:2001, Novaris data line protectors employ a spark gap for screen to earth protection. The spark gap that Novaris has selected for this role is a low capacitance gas filled surge arrester of the highest quality. It allows for 5kV 10/700ms let-through voltages of less than 350V for line to earth and screen to earth modes.
