Single-phase coupling/decoupling networks for EFT, Burst, Surge
The single-phase coupling/decoupling networks of the CNI 501x-series are used to couple EFT, Burst and Surge pulses to AC and/or DC supply lines.
Within the range of EMTEST coupling/decoupling networks, we offer different models for test voltages from 5kV up to 10kV with DUT currents of 16A, 32A, 63A and 100A (higher current ratings on request) for various test requirements and equipment configuration.
- Combined coupler for EFT, Burst and Surge test
- Surge test as per ANSI/IEEE C62.41 (models CNI 501Bx only, other couplers on request)
- LEDs indicate active mode and coupling
- Automatic selection of Surge impedance
- Fully remote controlled by EMTEST generators
- Meet requirements up to 1,000V DC
The CNI 501x-series coupling/decoupling networks are built fully complied to the standard of EN/IEC 61000-4-4 and EN/IEC 61000-4-5. Both residual voltages and induct value of decoupling are carefully considered in order to meet the requirements of voltage drop at the rated current of each type of CDN. Besides EN/IEC 61000-4-5 standard, the CNI 501Bx series are also fully complied with the surge test requirements outlined in ANSI/IEEE C62.41.
Coupling values of CNI 501x-series are set automatically by controlled generator and selected test (either by manual operation or via software). When performing surge tests, the generators will automatically set the required source impedance depending on the standard and the coupling mode.
