Descriptions
3-phase coupling/decoupling networks for EFT, Burst, Surge
The three-phase coupling/decoupling networks of the CNI 503x series are used to couple EFT, Burst 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 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 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. -
Highlights
- Combined coupler for EFT, Burst and Surge test
- 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 EMTEST generators
- Meet requirements for 3x690VAC and 1,000VDC -
Benefits
The CNI 503x-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 voltage levels and inducted 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 503Bx series are also fully complied with the surge test requirements outlined in ANSI/IEEE C62.41.
Coupling values of CNI 503x-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.
For DC EUT-supply, CNI 503 coupling networks offer an optional TEST ON function with a contactor up to 1,500 VDC / >100 A is available.
