Description

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.

To obtain maximum flexibility only coupling elements are included in the PCD 126A. Decoupling circuits, which depends on the EUT to be tested, can be placed separately in the test setup.

Manual coupling path switching for common mode (longitudinal, line to earth) and differential mode (transversal, line to line) testing.

Default coupling elements are capacitors, breakdown avalanche diodes and gas arrestors. The coupling elements can be selected easily. The direct coupling output allows the customer to use his own coupling elements.
The PCD 126A can be used together with the impulse modules PIM 100 and PIM 110 from the Surge Platform and the PSURGE 4010. These provide all the programming functions required to perform IEC, ANSI and EN testing also without the need of a control computer.
