The CDN 3425 is Teseq’s newly designed Burst EFT coupling clamp. It replaces the earlier models CDN 8014 and CDN 8015. The CDN 3425’s main purpose is to couple Burst/EFT pulses to data lines. It can also be used to couple to mains lines where no CDN is available; for example, high current lines >200 A.

This new design is fully compliant with the specifications of IEC 61000-4-4 Ed 2.0 2004, as well as with the draft of IEC 61000-4-4 Ed 3.0 to be published in 2012. An INA 3425 calibration kit as specified in IEC 61000-4-4 Ed 3.0 2012 is available as an option. An optional INA 3825 safety cover with interlock function to be connected to NSG 3000 series generators is also available.
