Test Equipment Description

Schloder CWG 520 3 Phase Coupling Network, 4 x 16 A - Burst and Surge

The coupling network (CDN) can be used to carry out EMC tests at 3 phase leads according to the standards IEC 61000-4-4 (Fast Transients) and IEC 61000-4-5 (Surge). The interference pulses of the burst generator or the surge generator are coupled to the power supply of the tested unit. The coupling paths can be changed by using the coupling switches. The coupling network can be remote from a personal computer via RS232- interface in connection with the burst generator SFT 1400 / 1420 or the surge generator CWG 1500.
