Decoupling network DEC 5

The DEC 5 is used for decoupling auxiliary equipment from an EUT tested with either 1,2/50 us - 8/20 us combination wave impulses or 10/700 us impulses up to 6.6 kV peak.  It is used to decouple unshielded symmetrical data and signal lines according standards IEC  61000-4-5 and ITU  K.44. Up to 4 wires can be tested simultaneously. To obtain maximum flexibility only decoupling and protection elements are included in the DEC 5. Coupling circuits, which depends on the EUT to be tested, can be placed separately in the test setup. Manual coupling selection of the protection elements for best protection of the auxiliary equipment. Default protection elements are gas arrestors and breakdown avalanche diodes. With such elements the capacitive load to the EUT lines is small. The decoupling elements can be selected easily. It is also possible to test without any protection elements. • Inductors 20 mH compensated • Combination wave 1.2/50 us - 8/20 us impulses 10/700 us telecom impulses • 100 kHz ring wave impulses • Breakdown avalanche diodes and gas arrestors as protection elements • Up to 4 wires can be tested • Signal Bandwidth up to some 100 kHz
