Introduction With the coupling network CWG 524-B EMC-tests (susceptibility) on electrical systems and devices can be performed. Basic for these tests is the standard IEC / EN 61000-4-4 (burst). The interference pulse of the burst generator is superposed to the feeding lines of the EUT. Using the coupling switch the coupling paths can be selected. Technical data Nominal voltage AC max. 230 / 400 V, 50-60 Hz; special voltage on demand Nominal current IN 4 x 60 A at TU= 30°Celsius Serial choke 5 x 100 – 150 µH Coupling capacity C 33 nF Surge: phase - PE 9 µF / 10 ? phase - phase 18 µF / 2 ?
