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. .
