Test Level With Burst As Per Iec 61000-4-4 Ed.2; Decoupling Inductors For Surge Pulse - EM TEST CNI 503 Series Manual For Operating

EM TEST
4.5.

Test level with Burst as per IEC 61000-4-4 Ed.2.

Burst generators, which comply with the specifications of IEC 61000-4-4 Ed2: 2004, have a limitation of the
maximum output voltage. Then the maximum test level is limited by the number of coupling on several lines.

Decoupling inductors for surge pulse

To prevent unwanted voltage drops in the coupling/decoupling networks, the value of the decoupling element
generally must be reduced for coupling/decoupling networks rated at >25 A. The Table below shows the reduced
inductor values per line in function of the rated current.
Rated current Inductance per line
16 A
32 A
63 A
100 A
200 A
For this case, the "time to half value" of the open-circuit voltage waveform may be reduced in accordance with
Tables 6 and 7 in standard IEC 61000-4-5.
