Teseq CDN 118-T4 Coupling Decoupling Network set for 1.2/50 µs and 10/700 µs Surge Pulses on 1 or 2 twisted pairs

Coupling/Decoupling Network for 1.2/50 and 10/700 Surging up to 2 pairs of balanced Data Lines

Teseq’s CDN 118 coupling-decoupling network is designed for convenient surge testing of telecom-
munications 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.

The user can manually select coupling modes by connecting the generator’s output to the appropriate input. All coupling methods described in the standard can be configured with the CDN 118.

Two CDN 118 main units can be arranged in parallel for testing eight line applications (low speed transmission only). It requires to combine CDN 118-T4 with the option CDN 118-EXT-1.

Setup example for testing according Annex A of IEC 61000-4-5 Ed.3
