Introduction:
CDN M2 125A 1000V is a two-wire coupling and decoupling network manufactured by SCHWARZBECK, Germany and authorized by Shenzhen EYT Company for sales and quotation service. This CDN coupling and decoupling network supports a maximum AC voltage of 500V and a maximum DC voltage of 1000V, and a maximum saturation current of 125A, which can be used for EMC testers to conduct conducted 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 lines of unshielded AC and DC power lines (utility). Tests.
This model is compatible with CDN M2 63A 1000V The biggest difference is that the test current has been expanded to 125A, supporting more DUT types.
