CCS 500 is an intelligent multi-function combined immunity tester, which can meet various requirements of international standards and product series standards for transient pulse, surge and voltage drop testing, and the test voltage can reach up to 5KV. CCS series combined immunity tester is the best choice for the fully compatible immunity test scheme. It not only meets the immunity test requirements of EU CE certification and CCC certification for single-phase equipment under test, but also has built-in automatic single-phase coupling/decoupling. It can also perform three-phase five-wire DUT testing through an automatically controlled external coupling/decoupling network (up to 100A).
