DEC 5
HAEFELY AG
Decoupling Network for Symmetrical Data and Control Lines
The Haefely 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 to 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 depend on the EUT to be tested, can be placed separately in the test setup.
Manual coupling selection of the protection elements for the 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.
