DCD SR
DCD SR - 系列 - 信号/数据线的耦合/去耦网络
浪涌脉冲或环波脉冲通过独立的耦合/去耦网络应用于非屏蔽的非对称互连线（信号/数据线
）。对于此类测试，阿美特克CTS提供一系列DCD，用于4或8条信号/数据线。 根据 IEC/EN 61000-4-5 和 IEC/EN 61000-4-12，脉冲通过不同的耦合元件（如电容器或气体避雷器）耦合，具体取决于数据线信号的特性。

TECHNICAL DETAILS
SURGE APPLICATION
DCD SR - SERIES - MULTIFUNCTIONAL
COUPLING/DECOUPLING NETWORKS
The AMETEK CTS DCD sr - series of coupling decoupling networks are multifunctional CDNs for the application of
Surge and Ringwave pulses onto signal/data lines.
The standard DCD sr - models combine three different applications; coupling of Surge pulse via capacitor or gas
arrestor and coupling of Ring wave pulses via capacitor being required by the relevant standards. The required
coupling mode can easily be selected.
The surge coupling GTD (Gas Discharge Tube) is inside a simple jumper and can be changed depends the
application with an ABD plug (Avalanche Breaking Diode).There are also two plugs for using an individual external
coupling device.
The DCD sr series also has the required decoupling inductors (20 mH) for each line. To protect the measuring
system, an interchangeable, pluggable voltage protection module with overvoltage protection for 50 VDC is included
in the delivery at the signal/data line inputs on the AE port. Each module protects 4 lines, so that coupling
networks with 8 lines require two modules.
AMETEK CTS offers coupling networks for various voltage pulses up to 7 kV as well as for signal currents up to 4 A.
Various modules for 50 VDC and 250 VAC are available for pluggable voltage protection on the AE port. Protection
modules for signal voltages up to 600 VDC are available on request.
Dedicated CDNs are available e.g. for railway applications as per EN 50121 and for other customer specific test
applications.
