The first contact with the power adapter friends may have a lot of doubts, such as: What is the power adapter? Why some electronic products with an external plastic shell power adapter, and some are not directly in the plastic shell inside the product circuit? What is the relative effect of using a power adapter? Under what circumstances is it better to use an external power adapter? Here are a brief introduction to these questions
The role of the power adapter is to provide the equipment to work the necessary energy. Is to power the device. Some of the external built-in, and equipment applications and designers. Because the power adapter has a corresponding over-temperature protection function, so the use of power adapter can protect the equipment from high temperature damage, stable and reliable work, but also over-current, over-voltage, overload protection, the device will not because of current, voltage Such as fluctuations in the damage. External power adapter to use more flexible, as long as the equipment can meet the requirements of the parameters, you can use the same adapter. However, in order to ensure the normal operation of the equipment, the choice must be selected when the regular manufacturers of power adapter.
External plastic shell power adapter in the use of certain benefits, such as the line can be extended to reduce the line of energy loss and so on.
