Unsymmetrical Coupled Decoupling Network Description
Unsymmetrical Coupled Decoupling Network โ DATA-CDN-4B Surge Tester for IEC 61000-4-5 Compliance
The Unsymmetrical Coupled Decoupling Network (DATA-CDN-4B) is a critical component for simulating lightning strikes and industrial switching transients on communication lines. As a specialized surge immunity test equipment, it enables the injection of high-voltage pulses onto high-speed data paths while isolating the auxiliary equipment from the test surge.
Testing rinciple
The network couples the surge waveform (10/700 ฮผs) from the generator to the equipment under test through a 0.5 ฮผF capacitor while the 20 mH decoupled inductor isolates the auxiliary equipment. Pluggable matching resistors allow precise impedance matching to the communication line, ensuring accurate and repeatable surge immunity testing according to IEC 61000-4-5 and related ITU-T recommendations.
