Voltage sag and short-term interruption are caused by the failure of power grid and power facilities or sudden large changes in load. In some cases, there will be two or more consecutive dips or interruptions. Voltage changes are caused by continuous changes in the load connected to the grid. If EUT cannot respond to the change of power supply voltage in time, it may cause faults. The cycle drop generator is used to evaluate the performance of electrical and electronic equipment when subjected to voltage sag, short-term interruption and voltage change. The product meets the requirements of new standards such as iec61000-4-11 and gb/t17626.11.
The DC drop generator VDT DC mainly provides an evaluation basis for the electrical and electronic equipment powered by the DC distribution system to be affected by the immunity of the power supply voltage sag, short-term interruption or voltage change during operation. The DC performance of the DC voltage drop generator VDT meets the requirements of iec61000-4-29 and gb/t17626.29.
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.
