CDN110 Datasheet
The Schaffner CDN 110 Coupling Network is an add-on for the Schaffner High Energy Pulse Generator NSG 650 to enable instrument and system tests to be carried out. The pulses generated can thus be coupled into the mains supplies to the instruments, systems and installations under test. These types of test are described in the test recommendations by the IEC 801-5, ANSI-IEEE C62 .41, IEEE 587, VDE 0109 and in many national standards. Surge and ring wave pulses of up to 4 kV are required depending on the class of the test performed. The Schaffner CDN 110 permits test pulses of up to 7 kV. The permissible EUT supply voltage of up to 420 Vac covers all the requirements from the mains feed point of view. A clearly labeled connector field enables any of the symmetric and asymmetric modes of coupling to be selected.
