CDNE M3 Introduction:

CDNE M3 is a coupling and decoupling network produced by Schwarzbeck, Germany and authorized by EUTTEST in Shenzhen, CDNEM3 is mainly used for the latest CISPR15 lamp test standard requirements of the conducted emission test, M3 model has three power cord interface so you can connect the three EUT's power cord test use.

Difference between CDNE and CDN:

Prior to the advent of CDNE, CDN coupling/decoupling networks were generally used for measuring conducted noise and immunity tests.The structure and usage of CDNE is mentioned in the latest standard of CISPR15 from 2018.Contrary to the coupling/decoupling network (CDN) described in IEC/EN 61000-4-6, CDNE can inject very little power and is particularly suitable for measurement of Conducted emission tests for luminaires with tighter impedance tolerances, so CDN can be used as a conducted immunity test, whereas CDNE cannot be used as a conducted immunity test.

Types of CDNE:

Depending on the number of power cords in the EUT DUT, you can use either of the following two CDNEs for testing.

CDNE M2 Coupled decoupling network (L,N)

CDNE M3 Coupling decoupling network (L,N,GND) (products on this page)

CDNE M3 meets the criteria:

The CDNE M3 from Schwarzbeck, Germany, complies with the conducted emission method of the latest EMC test standards for luminaires.

CISPR 15-2018 or newer standards

EN 55015-2018 or newer standards

The main technical parameters of the CDNE M3:

The parameters of the CDNE M3 and M2 are basically the same except for the frequency, so you only need to choose one model according to the number of cables to be tested.In addition, CDNE M3 cannot be used for two-wire EUT testing, so please contact us to purchase both CDNE M2 and CDNE M3 together if you need all the cables.
