CDN AF3 SCHWARZBECK Unshielded line coupling decoupling network

Product Description:

CDN AF3 is an unshielded line coupling decoupling network product manufactured by German SCHWARZBECK company, which can test three unshielded or unbalanced cables of EUT, and the product is authorized to act as an agent for sales and quotation service by Shenzhen EUTTEST.

This CDN coupling/decoupling network device supports an input AC voltage of 100V or a DC voltage of 150V at the DUT, has a rated input current of 4A, and can be connected to three unshielded or unbalanced data lines at the DUT.

AF Sequence CDN Scope of application:

AF Sequence CDNs are designed to be used by EMC testers for conducted common mode immunity testing according to IEC 61000-4-6 Annex D.2. We generally recommend that our customers use these CDNs for interconnecting cables between AEs and EUTs, and before settling on an AF Sequence CDN, you should prioritize the use of an AF Sequence CDN.CDN-M type,CDN-T type,CDN-S type coupled decoupling networksThe selected CDN should not unduly affect the functional signaling of the EUT, and the AF type CDN should only be used as a last resort when there is no alternative.

Technical parameters：

Product Specification Sheet:

In 2025, it is already necessary to introduce a frequency range of 10kHz-150kHz that can be measured. CDN10 AF3 The parameters are the same except the frequency expansion is lower, welcome to contact us for purchase.

Common mode impedance plot:

The following figure shows the common mode impedance curve of this product in accordance with the requirements of IEC 61000-4-6 and GBT 17626.6 conducted immunity test standard, the red line in the figure represents the impedance value range given by the standard.

Product Recommendation:

This product can only test two interconnecting cables. If this does not meet your requirements, we also offer the following AF Sequential Coupling Decoupling Networks with a wide range of interconnecting cable counts:

• CDNAF2 Tests 2 unshielded unbalanced lines
• CDNAF3 Tests 3 unshielded unbalanced lines
• CDNAF4 Tests 4 unshielded unbalanced lines
• CDNAF6 Tests 6 unshielded unbalanced lines
• CDNAF8 Tests 8 unshielded unbalanced lines
