A series of reliability tests are required for the power supply from production to putting it into the market. It is generally done in accordance with national basic standards, such as GB2423-2008 series of environmental test methods for electrical and electronic products. Frequently tested items include: high and low temperature, temperature cycle, temperature shock, damp heat, vibration, shock, IP protection level test, etc. Next, let's take a look at some conventional test items together!
