Benefits
The CNI 503x-series coupling/decoupling networks are built fully complying to the standard requirements of EN/IEC 61000-4-4 and EN/IEC 61000-4-5. Residual voltage levels are carefully considered as well as the value of the decoupling inductors in order to meet the requirements with regard to voltage drop at the rated current of each type of CDN. Apart from the coverage of the EN/IEC 61000-4-5 standard the CNI 503Bx series also fully complies with the surge test requirements outlined in ANSI/IEEE C62.41.
Being fully controlled by the related generators couplings of the CNI 503x are set automatically as selected for the 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.
For CNI 503 coupling networks for DC EUT-supply an optional TEST ON function with a contactor up to 1,500 VDC / >100 A capacity is available.

Meet requirements for 3x690VAC and 1,000VDC
The three-phase coupling/decoupling networks of the CNI 503x series are used to couple EFT/Burst pulses and Surge pulses on DC-lines or to three-phase (4-wire or 5-wire supply lines) mains supply systems for voltages up to 1,000VDC / 3x690VAC. This includes the more and more common testing of inverters used in the area of renewable energies (e.g. photovoltaic systems, wind power stations, electric cars).
Within the range of EM TEST 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 the various test requirements and equipment configuration.
