Your package may be returned to the original sender due to an incorrect or incomplete shipping address. Please contact the us Team and provide us with the correct shipping address and we will arrange a replacement for you.

Most engineers still focus on meeting the input and output voltage and power load requirements when selecting power supplies, which is only the most fundamental requirement. With the continuous development of the industry, the needs of customers vary accordingly. Some only require the function realization and low price; some require to meet the high reliability and low fault tolerance rate, which is caused by the different directions in selection. In general, the selection mainly focuses on conventional parameters, important parameters, and some hidden parameters that are not usually noticed. Of course, reliability is the most concerned parameter at this stage.

This is mainly for safety certification purposes. When certification authority tests product performance, they will make the input voltage range on the mark fluctuate by +10% and -15%, so the common practice in the industry is to set the input voltage range of 100VAC-240VAC on the mark.

If the large instantaneous current of the AC/DC Converters upon load access does not exceed the over-current protection point of the module, it will not have any impact on the module. See the datasheet for the over-current protection point of the module. If the current exceeds the over-current protection point of the module, the module will trigger the protection and voltage dip occur, and then recover.
