When the power adapter is in normal use, how much temperature is normal?

   Whether it is a power adapter or a charger, the temperature rise of the power supply itself is an important parameter.

   First: the reason why the power adapter is hot:

   When the power adapter is performing voltage conversion, a part of the energy is lost. Except for a small part of the loss in the form of waves, most of it is emitted in a thermal manner. The greater the power of the power adapter, the more energy is lost, and the heat generated by the power supply is greater.

   Second: When the power adapter is in normal use, what is the surface temperature?

   During the development phase of the power adapter, there will be a test evaluation of various parameter performances. Temperature is one of them. Under normal circumstances, the surface temperature rise of the power adapter will be controlled within 30-35 °C. As we all know, the power adapter is used indoors, then the indoor temperature is generally not higher than 40 ° C, normal is around 25 ° C. Then even at a maximum of 40 ° C, the power adapter's case temperature is also within 75 ° C. The temperature resistance of the outer casing is around 100 °C, and the temperature resistance of the nameplate sticker is around 80 °C. So 75 ° C is almost the limit. In fact, as long as the temperature of the power adapter is within the design range, that is, the temperature is within the normal range, it is generally not dangerous!

    Third: power adapter heating solution

   Power adapter heat is unavoidable, but it can speed up its heat dissipation and prevent its temperature from rising.

   1. When using in a high temperature environment, the power adapter should be placed in a place that is not exposed to direct sunlight and is ventilated;

   2, create a good cooling environment, the power adapter is placed in a position that is not exposed to sunlight and air.
