  • Complies with IEC 61000-4-5 edition 3

The Teseq’s CDN 117 can be used for all coupling methods described in IEC / EN 61000-4-5 for unshielded unsymmetrical line pairs and it can be performed both in differential- and common mode coupling (line-to line and line-to-ground).CDN 117 coupling-decoupling network enables convenient testing with surge pulses of 1.2 / 50 μs on data, signal or peripheral lines, as specified in many product standards. The user can manually select coupling modes by connecting the surge generator’s output to the appropriate input of the CDN 117. The test method, severity levels, permissible reaction of the EUT and specification of the coupling networks are included in IEC 61000-4-5 Ed.3 Chapter 
CDN 118 coupling-decoupling network is designed for convenient surge testing of telecommunications equipment to IEC / EN 61000-4-5, which specifies a 1.2 / 50 μs or a 10 / 700 μs pulse. The CDN 118 includes the special decoupling network and coupling devices that are required for these tests. The design of the CDN is given in IEC 61000-4-5 Ed.3 Figure 10 and A.4. The CDN 118 can be easily interfaced with the EUT and is designed as a bench top unit. It can be used with Teseq’s NSG series or any industry standard surge generator with the appropriate connector adapter.
