High Efficiency Power Adapter

Why do power adapters need to do salt spray testing?

Salt spray testing is a method of accelerated corrosion resistance assessment in an artificial atmosphere.... It is a certain concentration of salt water atomized, and then sprayed in a closed constant temperature box, by observing the changes in the sample under test after a period of time in the box to reflect the corrosion resistance of the sample under test. Why do we need to smoke test power adapters?

In order to verify whether the metal parts on the power adapter will corrode when exposed to the atmosphere or other environments. The power adapter can be left in use for a sufficiently long period of time, for example, for one life cycle of the power supply. This is time-consuming and labor-intensive and is rarely practiced. A convenient way to evaluate the corrosion resistance of power adapters is needed.

Salt spray test is an accelerated test method, that is, it takes a short period of time, not years, only a few days, or even a few hours, you can detect how the corrosion resistance of the power adapter, very efficient.

Although the salt spray test is an effective test method. However, due to the many factors affecting corrosion, a single resistance to salt spray performance can not be used as a representative of resistance to other media performance, so the results of the salt spray test can not be used as a direct guide to the corrosion resistance of the test material in all environments. At the same time, the performance of the material in the test can not be used as a direct guide to the corrosion resistance in use. Nevertheless, the salt spray test method can still be used as a method of testing the material under test.

Eahunt's power adapters have been upgraded to level 6 energy efficiency and can be widely used in all kinds of electronic products. In addition, these products have been in line with the United States, the European Union and other countries, the company did UL, CE and other certifications, the majority of consumers can rest assured that customers can buy play their own role can not be ignored, and continue to develop high-quality, high energy-efficiency products to cope with the market's increasingly demanding energy-efficiency requirements.
