EM TEST CNV508T5 – 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. The CNV508T5 is designed 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.
