CN

IEC/EN 61000-4-16 and IEC/EN 60255-26 specify the design and performance of a range of coupling networks. Each coupling network is related to the type of cable and connector. Ametek CTS offers extensive choices for CN based on the standards, number of lines and type of applications.

IEC/EN 61000-4-16 also specifies the decoupling network necessary in testing. Ametek CTS offers many decoupling network based on type of testing.

  • CN 4-16 A Series

    CN Type A is designed for testing the immunity of input/output signal and control ports of the equipment under test (EUT), with the capability to manually switch between AC and DC configurations. It operates within the frequency range of 0 Hz to 150 kHz, ensuring effective immunity testing against conducted disturbances in both power configurations.
