Switch power adapter three ways to quickly identify strengths and weaknesses
In switch power adapter in China research and development to the production control is very strict, but with the development of intelligent products constantly updated, the domestic power adapter industry is rapidly developing, different models, power switch power adapter has the influx of a large number of our lives, but due to price level and scale, the difference of the production process, then the quality of the production of power adapter, the price also can have very big difference, so how do we identify the strengths and weaknesses of the switch power adapter?
We can to quickly identify from four aspects, the first domestic example, first check the CCC certificate of switch power supply is effective, the second check the power adapter, carefully check the third interface and plug the power adapter.
In China for the control of the power adapter, is fall within the scope of the national compulsory certification directory.
So regular power adapter in the domestic market circulation of the national compulsory certification, when we buy power adapter, we first look to identify whether nameplate printed on the CCC mark, in addition we can inquire on the net this product certificate type, etc. , if the product has passed CCC certification, so we can choose the power adapter.
When after the completion of the first step we look at interface and plug the power adapter, first determine the size of the DC head to tell you the equipment is used, this is the most basic, if you are not match size that didn't also way, then watch the DC head will have loose case, because if the power adapter interface instability will cause the whole machine's current instability, can cause damage to equipment, safety accidents.
Finally, the switching power supply, actually this similar to the first point, but we confirm parameters, a qualified power adapter all the information, will be specified on the nameplate, such as voltage, current, energy efficiency, safety instructions, manufacturer, etc. , of course, if you just in the domestic use it sure are labeled in Chinese, but also will be very complete information.
Believe that after you read, must have a preliminary understanding of the switch power, when selecting a switch power adapter will not confused, want to know more information about the switch power adapter, please pay attention to the power adapter manufacturer in shenzhen, shenzhen moso technology co. , LTD. !
