Haefely-DEC 7 Decoupling Network for testing asymmetrically operated lines with Surge, Ring Wave 100 kHz, max. 4 wires
The DEC 7 is used for decoupling auxiliary equipment from an EUT tested with either 1,2/50ms-8/20ms combination wave impulses or ring wave 100kHz impulses up to 6.6kV peak. It is used to decouple unshielded asymmetrical control and data lines according IEC/EN standards. Up to 4 wires can be tested simultaneously.
To obtain maximum flexibility only decoupling and protection elements are included in the DEC 7. 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 varistors and breakdown avalanche diodes (ABDs). 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.
