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.
dc voltage dips and interruptions generator is a test device that simulates voltage dips, short interruptions, and voltage variations on dc input power port. vdt dc is specially designed for power fail simulation of dc systems. the product adopts a modular digital dc power supply system to provide customers with high-power dc output sources to meet the testing of different dc power systems. products meet the requirements of standards iec/en 61000-4-29 and gb/t 17626.29.
pulse voltage generator is mainly used for impulse withstand voltage test of electronic and electrical products and equipment. its performance meets the requirements of iec60060-1, -2, iec61010, gb311, gb/t16927.1-1997, gb/t16927.2-1997, gb/t116896.1-1997, iec 60255-5, gb14711 and other standards. this product is widely used in insulation performance test of various products.
