3ctest WCT 20 Wideband Current Transformer

The 3ctest WCT 20 Wideband Current Transformer is designed for conducted differential mode current testing in accordance with IEC 61000-4-19. It provides reliable signal coupling while maintaining electrical isolation between the signal generator and the equipment under test (EUT).

Engineered for accuracy and safety, the WCT 20 enables controlled current injection into the test setup, supporting both development and compliance testing. Its wideband performance ensures consistent behavior across a broad frequency range, making it suitable for EMC laboratory environments.

The EMC Shop customers use the 3ctest WCT 20 to inject differential mode currents into devices during conducted immunity testing. In a typical setup, the transformer is placed between the signal generator and the device under test (EUT), allowing controlled current injection while maintaining isolation for safe operation.

Engineers rely on the WCT 20 during both pre-compliance and full compliance testing to evaluate how systems respond to conducted disturbances. By applying repeatable current signals, they can identify susceptibility issues, verify system robustness, and ensure proper performance under EMC stress conditions.

In EMC labs, the WCT 20 is commonly used alongside signal generators and monitoring equipment to measure current response and validate test results against IEC 61000-4-19 requirements. This helps ensure accurate testing and reliable performance evaluation of electronic systems.
