electrostatic discharge is a common natural phenomenon (when a charged object approaches or contacts a conductor, the charge will be transferred, which is electrostatic discharge). its influence on electrical and electronic equipment, devices or systems is everywhere, and it is an electromagnetic energy with a very high degree of harm. only by improving the anti-static ability of electronic products can we ensure the safe use of electronics. in the automotive field, the requirements for electrostatic discharge are very strict. the on-board electronic electrostatic discharge generator rv esd is specially used to evaluate the performance of on-board electronic products, devices and systems subjected to electrostatic discharge. the products meet the requirements of new standards such as iso 10605 and gb/t19951.

voltage dips/sags, short interruptions are caused by failures of the power grid and power facilities or sudden large changes in loads. in some cases, there will be two or more consecutive dips or interruptions. voltage changes are caused by continuous changes in the loads connected to the grid. if the eut cannot respond in time to changes in the power supply voltage, it may cause malfunctions. voltage dips generators are used to evaluate the performance of electrical and electronic equipment when subjected to voltage dips/sags, short interruptions, and voltage changes. products fully meet the requirements of standards iec/en 61000-4-11 and gb/t17626.11.
