Haefely PCD 121 Coupling Network


Coupling Network for Symmetrical Data and Control Lines

The PCD 121 is used for coupling of 1,2/50us – 8/20us combination wave impulses up to 6.6kV peak onto unshielded symmetrical data and signal lines according IEC/EN standards. Up to 2 pairs / 4 wires can be tested simultaneously.
