The CDN 3153 series are 3 phase coupling/decoupling networks designed to offer best price performance for use as extension to NSG 3150 generator. The coupler is characterized by a high level of user comfort and common safety functions. All coupling status are clear indicated on the display of the NSG 3150 generator. The fully automated and IEC compliant coupling networks fulfill the requirements for EUT currents up to 63 A in the surge standard IEC / EN 61000-4-5 (latest edition). EUT power ON and OFF accessible via the user interface. High Voltage safety plugs are used to interconnect the high voltage pulse output from NSG 3150 multifunction generator to CDN input. The CDN 3153 perform dynamic cooling. Internal elements which warm up under load are equipped with thermal sensors. At standby or for lower EUT currents, when there is no need for cooling, the fans will turn at a very low speed, generating no noise. In case of intentional or unintentional overloading, there will be a point where even full speed cooling will no more be sufficient, at this moment the CDN 3153 will switch OFF EUT power through the built in EUT power contactor, and so avoid destruction of the instrument (risk of fire). The CDN 3153 is designed to cover the surge waveform standard as per IEC 61000-4-5 and is able to conduct high inrush currents or peak loads. The phase synchronization is taken from the phase L1 of the 3-phase coupling.
