EM TEST CNV504 / 508 T-series - Coupling decoupling networks for unshielded communication lines

Surge pulses and Telecom Surge pulses are applied to unshielded symmetrical interconnection lines (communication lines) by means of standalone coupling/decoupling networks.

CNV 504T5 is designed for 4 lines (2 pairs), CNV 508T5 for 8 lines (4pairs) and can also be used for either 4 or 2 lines.

According to IEC 61000-4-5 Ed.3, (Fig. 10) the pulses are coupled via gas arrestors and a matching resistor per line.
