Coupling Network

Combined 3-phase coupling/decoupling networks for Burst and Surge testing up to 10kV

  • Combined coupler for EFT/Burst and Surge
  • Surge as per ANSI/IEEE C62.41 (models CNI 503Bx only, other couplers on request)
  • LEDs indicate active mode and coupling
  • Automatic selection of Surge impedance
  • Fully remote controlled by EM TEST generators

EM TEST CNI503x Coupling/decoupling networks for EFT/burst and Surge

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, 100A and 200A for the various test requirements and equipment configuration.
