SPD for coaxial connection

CCTV Handbook 2012 Products

DEHN’s UGKF surge arresters are shielded devices for plugging into coaxial terminal devices or connections in computer networks or outdoor video surveillance systems. In order to avoid being influenced by stray earth currents, the cable shield is earthed indirectly via a gas discharge tube. The arrester entries are used as sockets and protected outputs as plugs.

The UGKF SPDs are installed upstream of the network card and the earth conductor is connected to the earth electrode of the enclosure.

Designed for use in the LPZ concept at boundaries 0B –2 and higher, the UGKF BNC model is suitable for protecting video cameras with BNC connection. Operating on 5 V, it has a 2,5 kA (8/20) discharge current with 10 Ω impedance per line. Special units for video cameras with higher nominal voltage are available.

DEHN is represented locally by Surgetek.
