They are all buying lightning surge generators. Why is the quality difference so great

Everyone must know something about lightning surge generator. Lightning surge generator is applied in many industries, such as industrial equipment, household appliances, medical devices, intelligent equipment, lighting appliances, communication transmission, audio and video equipment, low-voltage electrical appliances, electronic components, electric tools, power equipment, information technology equipment, rail transit and spacecraft, instrumentation and other industries, However, as the lightning surge generator market matures, more and more counterfeit products continue to show up in our field of vision, so we should be more careful when buying lightning surge generators! Today, Xiaobian will tell you how to buy safe and assured products in our purchase of lightning surge generator

First of all, we should choose the instrument that can provide pulse test voltage up to 6kV, which is also good for the future upgrading of technical standards, and can avoid the embarrassment after the upgrading of standards, so as to better protect everyone’s interests from damage.

Secondly, it is best to choose the lightning surge generator with high-voltage fast induction principle, which can realize ns level high-speed on-off switch with high stability and long service life.

Then choose the lightning surge generator with high automation integration, such as the instrument with automatic switching function of positive and negative polarity, voltage level and phase angle, so that our test process can be unattended.

Finally, there is the problem of after-sales. For instruments such as lightning surge generators, if the warranty period is two years, customers can save part of the maintenance cost.
