Product Information Electrostatic discharge (ESD) is a common natural phenomenon. The effects of ESD on electrical and electronic equipments, devices or systems are everywhere. It is a very high degree of harmful electromagnetic energy. Only to improve the level of anti-static interference can ensure the safe use of electronic products. ESD genertor is used to evaluate the electrostatic immunity performance of electrical components and electronic equipments by simulating real We are also ISO9001 certified. Our self-developed electrostatic discharge (ESD) generator, electrical fast transient (EFT)/ burst generator, lightning surge generator, voltage dips simulator and so on have won a high reputation both at home and abroad. With the company's unique product support, application technology, system supporting capabilities and high quality service, we offer our users the most comprehensive testing program.
