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.
power supply voltage
cdn (coupling/decoupling network)
number of tests
1~80v (customer specific on demand)
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.
the lightning surge generator sur 6ka 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.
p1 is the transient phenomenon generated when the analog power supply is disconnected from the inductive load. it is applicable to the situation that various duts are directly connected in parallel with the inductive load when they are used on the vehicle; p2a simulates the transient phenomenon caused by the sudden interruption of the current in the device in parallel with the dut due to the inductance of the harness. the on-board electronic transient interference simulator rv p1p2a meets the latest requirements of iso-7637-2 and gb/t21437.
