EFT-5K16 EFT immunity measurement
1. Introduction:
Electrical fast transient generator is designed according to IEC61000-4-4. It is widely applied to the fields of industry control appliance, household appliance, medical equipment, components, auto cotnrol equipment and etc..
The electrical fast transient/ burst generator is to simulate the electrical fast transient or burst, the repetitive fast transient test is a test with bursts consisting of a number of fast transients, coupled into power supply, control, signal and earth ports of electrical and electronic equipment.
The test voltage of burst generator is from 0.25KV to 5KV, which can cover all the test levels, and user can define the test level. The high amplitude, short rise time, high repetition rate are completely meet the requirment of IEC61000-4-4.
The electrical fast transient/burst generator is built in a 380V/16A CDN.
EMC Test equipment includes: EMI receiver, ESD generator, surge generator, electrical fast transient generator, voltage dips short interruptions and voltage variatins generator, ring wave generator and etc.
