Function: |
|
RX-SPDJK4 video lightning arrester is specially designed for video surveillance control system, it mainly | |
prevents the DVR video circuit from high voltage and heavy current that made by thunder induction. | |
This product is specially fit for protecting long-distance transmission circuit, like coaxial-cable of video surveill | |
-ance system. The coaxial-cable (which enters the control room) only needs to connect the RX-SPDJK4, then, | |
it can effectively prevent the end matrix, digital video tape recorder, monitor, from such damage which made by | |
over voltage reaction and static discharge. It is fit for railway communication system, locomotive basic establish | |
-ment station, transfer station, catv, common television, surveillance control system, satellite TV receiving system | |
and video selection swift system. | |
Feature: |
|
1. Adopt multilevel protection circuit, low-level persistent voltage. | |
2. Adopt the famous Siemens brand core components, and full copper BNC connector. | |
3. It has great flow capacity, sensitive reaction. | |
4. Excellent performance, and low-loss insert. | |

Installation and Maintenance: |
|
1. This video lightning arrester is used for preventing thunder through checking the high voltage pulse signal of | |
circuit, and to limit the high voltage, ruinous voltage by the three-level protection circuit of the lightning arrester. | |
2. When you use it, please link the easy-react circuit with the Input, link the Output with the end matrix, digital | |
video tape recorder, monitor equipment and so on. |
