Power adapter in normal use, the temperature is how much normal?
Jan 11, 2018

First: The reason why the power adapter is hot:

Power adapter in the voltage conversion, a part of the energy loss, in addition to a small number of waves in the form of loss, most of the heat is the way to emit out. The greater the power of the power adapter, the more energy it loses, and the greater the calorific value of the power supply.

Second: The normal use of the power adapter, surface temperature is how much normal?

During the development phase of the power adapter, there will be a variety of test evaluations of parameter performance. The temperature is one of them. Generally, the surface temperature rise of the power adapter will be controlled within 30-35 ℃. As we all know, the power adapter is used indoors, then the indoor temperature under normal circumstances will not exceed 40 ℃, normal is around 25 ℃. Then even if the maximum 40 ℃, the power adapter shell temperature is within 75 ℃. The temperature of the shell is about 100 ℃, and the temperature of the nameplate sticker is about 80 ℃. So 75 ℃ is almost the limit. In fact, as long as the temperature of the power adapter is in the design range, that is, the temperature in the normal range, generally will not be dangerous!

Third: Power Adapter Heating Solution

The power adapter heat is unavoidable, but it can accelerate its heat dissipation to prevent its temperature from rising continuously.

1, in the high temperature environment to use, the power adapter should be placed in direct sunlight and ventilated places;

2, create a good thermal environment, the power adapter placed in the sun is not exposed to the location of the ventilation.
