Test Equipment Description

The 3ctest SG 5020H series fully automatic lightning surge test bench is based on 3ctest third generation intelligent test generator with the technology of programmable control and computer technology, its system composition is simplified greatly and reliability is improved. This enhances the security of the system in high voltage and current tests to avoid the equipment may suffer from the harm during high voltage discharge transient process. With unique color touch screen operation interface and convenient and simple operation, simple test requirement setting is just performed on the parameter setting pages, kinds of tests can be completed automatically. It has the advantages of high system integration, intelligent control, easy and simple operation, saving test time, etc.
