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.
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.
the fault simulator of on-board electronic power supply simulates the starting, opening and closing of vehicles; changes or abnormal conditions in the on / off state of electronic devices or in the charge / discharge state of batteries, including multiple tests such as superimposed ac voltage, voltage sag, voltage startup, etc., are ideal interference sources for evaluating the power failure immunity of on-board electronic equipment. the on-board electronic power failure simulator rv 16750 meets the new requirements of iso 16750-2.
