Test Equipment Description

Schloder CWG 524 60A Coupling Network

With the coupling network CWG 523 / 524 EMC-tests (susceptibility) on electrical systems and devices can be performed. Basic for these tests is the standard IEC / EN 61000-4-4 (burst) and IEC / EN 61000-4-5 (surge).

The interference pulses of the burst and surge-generators are superposed to the feeding lines of the EUT. Using the coupling switch the coupling paths can be selected.
