Haefely PCD 126A Coupling Network

Coupling Network for Asymmetrical Data and Control Lines

The PCD 126A is used for surge coupling of 1,2/50us – 8/20us combination wave impulses onto unshielded asymmetrical data and signal lines according IEC/EN standards. It is also used for surge coupling ring wave impulses onto both unshielded asymmetrical and symmetrical data and control lines according to IEC/EN standards. Up to 6.6 kV peak value are possible. Up to 4 wires can be tested simultaneously.
