The CDN M2/M3PE 16A is a part of the coupling decoupling network series for conducted common mode immunity testing according to IEC 61000-4-6. The CDN M2/M3PE 16A complies to IEC 61000-4-6 Annex D2 and is suitable for immunity testing on unscreened a.c. and d.c. power supply lines (mains lines).
The CDN M2/M3PE 16A is intended to inject common mode disturbance signals to power supply or mains lines (unscreened) in the frequency range from 150 kHz to 230 MHz. The circuitry schematics are shown in fig. 5 and fig.6.
By switching this CDN can be used as CDN M2 (for L and N or for DC+ and DC-) or alternatively as CDN M3PE (L,N,PE).
All CDNs comply to the requirements of IEC 61000-4-6. Each CDN comes with individually measured data and a calibration certificate for the common mode impedance and the voltage division factor. Further typical data can be found in Fig. 3 and Fig. 4
A variety of calibration adapters and other accessories are available as options.
The optional shorting adapters must not be used if the CDN is connected to mains! Use the 2 pin adapters for M2 calibrations, use the 3 pin adapters for M3 calibrations!
The capacitors at the AE-side are equipped with 2 MΩ discharging resistors. The connection to ground can be accomplished using the ground plane of the CDN. Additionally there is an M4 thread located at the AE side to ground as well as a 4 mm socket to connect the device to ground.
To improve the operational safety the mains voltage-carrying connections are carried out as security sockets. We recommend to use special 4 mm security plugs if you plan to design your own adapters. Those connectors can be purchased optionally.
