Haefely PCD120

Haefely PCD120 The Haefely PCD120 CDN, 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.The 10/700µs test system includes with the impulse module PIM 120 and the automatic coupling network PCD 120. It is used to generate and superimpose 10/700µs 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 Haefely PIM120 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.PSURGE 8000 Surge Platform provides all the programming functions required to perform IEC, ITU and testing without the need of a control computer. Voltage and Cur 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.Features of the Haefely PCD120 and PIM120 Telecom Test Impulse Module include:

10/700us impulse shape up to 7.4kV

according to ITU K.44

Fully automatic coupling network

Cur limit resistors 25 Ohm, 50 Ohm, 75 Ohm and 100 Ohm

Coupling elements user changeable, gas arrestor 90V are standard

Selected resistors and coupling elements clearly shown on the PCD 120 front panel

WinFEAT&R software integrated

Highlights of the Haefely PCD120 and PIM 120 include:

International application – Specifically designed to meet and exceed the requirements of ITU and IEC / EN and tests for telecom and data line applications.

Safe and Easy - The interlocked HV section and the special HV sockets allow your operators to test safely and easily.

Sturdy and Reliable – Careful component selection ensures that the PIM 120 and PCD 120 will continue to operate under the most strenuous testing regime.

Report Generation - The test system can automatically generate test reports without a computer. Add WinFEAT&R control and reporting software to collect and collate data in any format you like.

Fully flexible solution - The PIM 120 connects to an EUT via the PCD 120. Decoupling units are also separate and can be selected according to application.

Applications include:

Resistibility tests

ITU K.20, K.21 & K.45 Telecom Interfaces

EMC tests

IEC 61000-4-5 Data lines

Safety tests
