SALTEK DMS-048T SPD – Data, Signalling and Telecommunication

Description
Reviews (0)

Coupling impedance (resistance).

Special two-stage surge protection of 2-core signalling line with current limiting.
Installation close to protected equipment.
For protection of communication interfaces, mainly the measuring loops, of I<(>&<)>C, electronic security and fire detection systems, etc. against surge voltage where are long parallel lines with power network.
Coarse and fine surge protection in differential mode (core – core) and coarse surge protection in common mode (core – PE).
