Introduction:
CDN M3 32A 1000V is a three-phase coupling and decoupling network manufactured by SCHWARZBECK, Germany and authorized by Shenzhen EUTTEST Company for sales and quotation service. This CDN coupling and decoupling network supports DUT line-to-ground voltage up to 500V AC and 1000V DC, and maximum saturation current up to 32A, which can be used for EMC testers to conduct conducted common-mode immunity test according to IEC 61000-4-6 Annex D.2, and is suitable for conducting immunity test along the power line of unshielded AC and DC power lines (utility). It is suitable for conducting immunity tests along power lines for unshielded AC and DC power lines (mains).
This model is compatible with CDN M2 32A 1000V However, the CDN M3 introduced on this page extends the two-wire mode of the CDN M2 32A 1000V to the three-phase power line without ground (L1,L2,L3 three-phase) of the CDN M3, so please select the appropriate test equipment according to the number of power lines of the object under test.
