KNFDB Series Of Serial Signal Lightning Protection Gate

 

KNFDB series of serial signal lightning protection gate is mainly used for information technology equipment 

and equipment from lightning and lightning electromagnetic pulse caused by induction over voltage 

protection, with overvoltage protection road (primary and fine grade protection) plug-in adapter, 

equipped with a D-Sub plug (9, 15 and 25 pin)

Installation And Maintenance

1.This product series in the protected equipment signal circuit, and close to the protected equipment.

2.The input and output cannot be reversed; the input is the lightning intruding end, output is connected with 

   the protection device.

3.For the normal work of SPD, grounding is very important, the grounding wire cross-sectional area is 

   no less than 4m square meters, and as short as possible.

4.Lightning protection gate without special maintenance, but its long-term energized, so need messenger to

   inspect regularly, especially in the thunderstorm season, after the lightning strike, it should be inspection on

  time, if found that the loop signal is abnormal, removing protection gate, loop signal will back to normal, it 

  means Lightning protection gate has been damaged or life has ended, replace the new lightning protection

  gate on time.

5.The outside length of Coaxial line more than 30m,it should be in the coaxial two ends with lightning 

   protection gate to ensure the best lightning protection effect.
