Protection against electro-magnetic interferences on the line including transient surge suppression

SPDs for signalling and telecommunication networks

Typical installation: in series with the signalling/telecommunication circuits for equipments with "low resistability" according Recommendation ITU-T K.45 / "low surge immunity" according IEC/EN 61000-4-5.

Features:

SPDs with impulse ratings for C1, C2, C3 and D1 categories (according to IEC/EN 61643-21).
SPDs with common mode and differential mode protection against symmetrical and/or asymmetrical disturbances.
SPDs with disconnecting means in case of accidential contact between the signal/telecommunication circuits and a power line (e.g. 230/400V a.c.) due to isolation faults.
SPDs with integrated earth/protective ground connection via the 35 mm top hat DIN rail and by screwless spring type termination of the cable screen.
SPDs with RJ and LSA connectors.

Specific with Coaxial connectors

Typical installation: for the protection of TV switchboards, satellite antenna or wideband transmission equipment and remote systems. Particularly suitable for applications with long coaxial cables which are exposed to electromagnetic interference.

Features:

SPDs with type F connectors for the protection of antenna circuits used in civil applications.
SPDs with BCN type connectors for CCTV circuits.
SPDs with 7/16 M/F type connection for coaxial cables of antenna circuits and telecommunication systems (4 and 3G).
SPDs with special connectors/connection can be supplied upon request.

ZOTUPSIGNAL

S-AS 2 is an SPD for installations in series with the telecommunication/signalling circuits to protect sensitive equipments with low resistability/immunity, providing the following features and benefits:

Common mode and differential mode protection make it particularly suitable for signal circuits between equipment with reference ground;

Very efficient protection providing a low voltage protection level Up;

Providing protection against indirect lightning effects;

Suitable for installation at LPZ boundaries up to 0B -2 in accordance with the lightning protection zones concept;

The behaviour of the SPD is in Short Circuit failure mode when reaching the end of the life;

Ground connection is made via PE screw type terminals.

Note: Equipment protection at both ends of the telecommunication/signal line is essential (see above schematics).
