In the circuit, such as from the switching transient process (cutting off inductive loads, bouncing relay contacts, etc.), it will usually interfere with other electrical and electronic equipment in the same circuit. This kind of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. Clusters of narrow pulses can charge the junction capacitance of semiconductor devices, which may cause circuit or equipment errors when accumulated to a certain extent. The burst generator determines a common reproducible evaluation basis for evaluating the performance of power supply ports, signal, control and grounding ports of electrical and electronic equipment when disturbed by electrical fast transient bursts. The products meet the requirements of new standards such as iec61000-4-4, en60100-4-4 and gb/t17626.4.

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.
The lightning surge generator sur 20KA is used to inspect the anti surge protection devices such as zinc oxide arrester valve piece, varistor, SPD, TVs tube, gas discharge tube, etc. for surge impact test. The product produces 8/20us surge pulse waveform, and the technical indicators of the waveform comply with the provisions of national standards and IEC standards.
