An EFT generator will operate with a short rise time, high rate of repetition and generate relatively low energy transients, with the intention of emulating the switching of inductive loads. The switching of inductive loads in the field can be the toggling of an electric switch, a motor and relay system or adjacent bundles of cables. Interference of electrical and electronic equipment may lead to performance decline or failure, resulting in malfunctions, and even reduced reliability. In order to evaluate the product’s immunity to this kind of electric fast transient/burst, a fast transient immunity test is normally required. Then how to choose an EFT generator?
1. Judging from production details of the EFT generator
For this kind of precise instrument, you should first check whether there is a certificate when purchasing it. At the same time, you should carefully check whether the generator has corresponding protective measures, whether it has protective effect against electrostatic dust, and its waterproof performance. And whether it is well manufactured, whether the gap processing is good. Check the size of the display screen, and whether relevant operations can be carried out directly through the touch screen, which facilitates the test operation, improves the use efficiency.
2. Judge from some functions of the EFT generator
EFT/burst generators are widely used. Once purchased, there may be more products that need to be tested. So, the frequency of use will be relatively high. When selecting fast transient generators, you may pay attention to its repetition rate control range, and other accessories must also be matched to prevent unnecessary failures during testing.
Because the electric fast transient burst generator has a wide range of applications, once purchased, there may be many products that need to be tested, so the use frequency will be relatively high. When selecting the electric fast transient burst generator, you can pay attention to understand its repetition frequency regulation range, and other matched accessories to prevent unnecessary failures during test.
3. Judging from the service of manufacturer
The price of purchasing such a precision and professional instrument is not cheap, so after-sales service cannot be ignored. See how long the warranty period is, how many times and times of free maintenance are provided, whether there is technical guidance, etc. In order to ensure that the electromagnetic energy generated between some electronic equipment in the factory does not interfere with each other, it is very important to choose the correct and suitable EFT/burst generator, which will benefit to the EFT immunity test.
