Introduction:
CDN M2/M3PE 16A is a 3-wire coupling and decoupling network manufactured by SCHWARZBECK Company in Germany, authorized by Shenzhen EUTTEST Company for sales and quotation service. This CDN coupling and decoupling network supports a maximum AC voltage of 250V and DC voltage of 400V, and a maximum saturation current of 16A, which can be used for EMC testers to conduct common mode immunity tests according to the IEC 61000-4-6 Annex D.2 standard, and is suitable for conducting immunity tests along the power supply line of unshielded AC and DC power lines (utility).
This model is the same as the CDN M2 16A 1000V, but with the addition of a GND ground port to turn it into a three-wire CDN, ideal for testing conducted immunity for DUTs that require a three-plug power supply (with a protective ground wire) during operation. The device supports CDN M2 or CDN M3 modes, which can be freely selected, and is included with the purchase of the device on this page. CDN M2 16A 1000V All the features of the
