In daily use, due to the complex application environment, component damage and so on, it is possible to cause the problem of no output power after power on, so that the post-stage circuit can not work normally. So what are the common causes?
There are lightning strikes, surges or voltage spikes at the input end
Checking scheme: check whether the front-end fuse, rectifier bridge, plug-in resistor and other components of the input products are damaged, and use differential test to analyze the electrical waveform. It is recommended to be used in the environment in accordance with the EMS conditions of the technical manual. If it is needed to be used in more severe environment, it is necessary to add EMC filter and anti-surge device in the front end of the product.
Input voltage far exceeds the maximum specification value of the product
Checking scheme: check whether the product input fuse, plug-in resistor, large capacitor and other devices are intact, and test the input voltage waveform for judgment. It is recommended to adjust the input voltage, use the power supply with the appropriate voltage as the input, or replace it with a product with a higher input.
There is water or tin residue and other sundries attached to the product, resulting in internal short circuit
Checking scheme: check whether the environmental humidity is within the specifications, and then open the product to check whether there is debris on the patch surface, and whether the bottom surface is clean. It is recommended to ensure the clean environment of the test (use), and the temperature and humidity are within the specification range. If necessary, the product should be painted with three anti paint.
The input line is broken or the connection line end is not in good contact
