Coupling NX7 bsr-3-690-125.3

Overview

The three-phase coupling/decoupling networks of the coupling NX series are used to couple EFT/Burst-, Surge- and Ring wave pulses on DC-lines or to three-phase (4-wire or 5-wire) mains supply systems for voltages up to 1,000 VDC / 3 x 690 VAC. 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).

Full compliance over a wide range of EUT current, within 16A , 32 A, 63 A, 125 A and 200 A settings. Higher current ratings on request.

Benefits

The coupling NX-series coupling/decoupling networks are built fully compliant to the standard requirements of EN/IEC 61000-4-4, EN/IEC 61000-4-5 and EN/IEC 61000-4-12. 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.

Being fully controlled by the related generators, couplings of the coupling NX 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.

Models are available with multiple current ranges with waveshape specification that are fully compliant to IEC 61000-4-5. in each selectable EUT current range. Offering the advantage that nearly all EUT's can be tested with just one CDN!
