Haefely DEC 7 Surge Decoupling Unit

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.
