The CDN3063-c32 is a automated 3-phase coupling network for burst (EFT) and surge (combination wave, ring wave). This fully automated IEC and ANSI compliant coupling network fulfills the new requirements for EUT currents over 16 A in the surge standard IEC/EN 61000-4-5:2005, as well special coupling modes and pulse amplitude control in the ANSI C62.45 standard, the ring wave pulse given in IEC/EN 61000-4-12:2006
and the EFT in IEC/EN 61000-4-4
The CDN 3063 couples surge and burst pulses into 1-, 2- or 3-phase power mains of up to 480 V with a current range up to 32 A. This range incorporate the new IEC draft standard’s provision for testing EUT’s with high power consumption. Reduced decoupling inductances in series with the EUT power connection are specified in order to minimize series voltage losses. The draft standard defines three classes of filter inductance for the following current ranges: up to 20 A, 20 to 60 A and 60 to 100 A.
The CDN 3063 in combination with the NSG 3060
completely fulfills the unique coupling requirements specified by ANSI C62.41. This standard requires a constant peak voltage amplitude for any EUT mains voltage and phase angle. This can only be realized when the instantaneous EUT mains power voltage at the selected phase angle is taken into account when the surge voltage is applied. The instantaneous mains voltage must either be subtracted from or added to the surge generator setting in order to keep the peak level constant with respect to ground (PE). Otherwise, the mains voltage is summed with the surge pulse amplitude thereby increasing or decreasing the stress on the EUT from the desired level.
