Product description
DataPro-Koax-8V-BNC was developed to protect sensitive COAX-systems or devices against overvoltages
caused by lightning surges. The arrester has a current impulse discharge capability of 10kA test wave form
8/20µs and reach a voltage protection level of < 20V.
The protection circuit has 2 stages. The coarse protection is realized by a high performance GDT filled with
inert gas. The second stage for fine protection consists of a EMI-Filter and a diode combination with low
capacitance for reliable transmission at high data transfer rate. Because no MOV is in this protection circuit,
no substantial leakage current can happen.
You can choose between BNC-50Ω and BNC-75Ω execution.
The extreme speedy fine protection by high performance suppressor diodes allows a fast equipotential
bonding between wire and shield within only 2ns
Application
This DataPro-Koax-8V-BNC has excellent features to protect COAX devices or systems against surges
caused by lightning and transient disturbances, e. g. for Video-surveillance systems against intrusion or
video monitoring in parking houses and public places, airports, railway stations, universities, etc.
Everywhere a high reliability and uninterrupted availability is highly requested.
It can be installed at the boundary 0B - 2 or higher according to the Lightning Protection Zone Concept
(LPZ) in standard IEC EN 62305 part 1-4 (VDE 0185-305-1-4). The protection is as better as nearest the
DataPro-Koax is installed to the electronic device to be protected.
