　　Combined Coupling/Decoupling Networks for EFT/Burst and Surge Testing

　　The CNI 503X series three-phase coupling/decoupling networks are used to couple electrical fast transients/bursts and surge pulses onto DC power lines, or three-phase (4 line or 5-wire power cord) power supply system. This has increasingly become a common testing requirement for inverters in the field of new energy (such as photovoltaic systems, wind power stations, electric vehicles, etc.).

　　For different test requirements and equipment configurations, EM TEST provides various types of coupling/decoupling networks, the voltage range is 5 kV to 10 kV, the current of the equipment under test meets 16 A, 32 A, 63 A and 100 A, and can Customized coupling/decoupling networks for higher current ratings.
main feature:

　　Combined Coupling/Decoupling Networks for EFT/Burst and Surge Testing

　　Surge test meets ANSI / IEEE C62.41 standard (only CNI 503BX model, other coupling networks can be customized)

　　LED indicators show test status and coupling method

　　Automatic selection of surge impedance

　　Can be remotely controlled by EM TEST test simulator

　　Compliant with 3 x 690 V AC, 1,000 V DC

Standards compliant:

　　ANSI/IEEE C62.41

　　IN 61000-4-12

　　EN 61000-4-4

advantage:

　　CNI 503X series coupling/decoupling networks fully meet the requirements of EN / IEC 61000-4-4 and EN / IEC 61000-4-5 standards.

　　The design of CNI 503X fully considers the residual voltage level and decoupling inductance value, so as to meet the standard requirements for voltage drop under rated current for each coupling/decoupling network. In addition to meeting the EN / IEC 61000-4-5 standard, CNI 503BX series coupling/decoupling networks also fully comply with the surge test requirements of the ANSI / IEEE C62.41 standard.

　　The coupling parameters of CNI 503X are automatically set by the relevant simulator controlling it when selecting the test item (both in manual operation mode and software control mode). When performing a surge test, the test simulator can automatically set the required source impedance value according to the standard requirements and coupling mode.

　　For DC EUT power supply applications, the CNI 503X coupling network has the TEST ON function (option) with a DC 1,500 V / > 100 A contactor.
