The CWS 120G series is a high-end testing equipment specifically designed to simulate low-voltage surge pulse interference phenomena. It is suitable for testing surge protection devices (such as TVS tubes, TSPDs, SIDAC, surge suppressors, etc.) and can also be used for surge immunity testing at the wafer or package level. The output voltage range is adjustable from 1 V to 1200 V, and the technical parameters fully meet the requirements of IEC/EN 61000-4-5 and GB/T 17626.5 standards. The CWS 120G design is based on the third-generation intelligent control platform, which has the advantages of high system integration, intelligent control, easy operation, and saving testing time.
