Haefely PSURGE 10/700us Telecom Impulse Test System (PIM 120/PCD 120)

To test telecom systems the 10/700us impulse also called telecom impulse is used. This impulse is characterized by high energy and a relative fast rise time.

The 10/700us test system includes with the impulse module Haefely PIM 120 and the automatic coupling network PCD 120. It is used to generate and superimpose 10/700us impulses onto telecom and other communication lines.

The Haefely PCD 120 as part of the PSURGE 8000 system is tailored to meet the ITU and IEC requirements for 2 & 4 wire interfaces. It allows the selection of both the required resistors and coupling elements and to perform a fully automatic test sequence.

Safety is paramount with surge impulses. The PIM 120 High Voltage connections are all linked into the System Safety Concept which prevents high voltage plugs or cables from exposing operators to potentially lethal voltages. The PCD 120 has special HV output sockets to guarantee maximum safety for the user.

Haefely PSURGE 10/700us Telecom Impulse Test System (PIM 120/PCD 120) provides all the programming functions required to perform IEC, ITU and testing without the need of a control computer. Voltage and Current peak measurement circuits are used to help determine EUT PASS/FAIL criteria. The integration in the WinFEAT&R control and reporting software package enhances an efficient set-up and operation of this test system. Most importantly, the test load can be transferred to a computer freeing valuable resources.
