The manufacturer of 12V2A power adapter tells you that the power adapter is actually a comprehensive transformer composed of a transformer, an AC/DC converter and a corresponding voltage regulator circuit. In short, this comprehensive transformer contains two main components, a transformer and a current converter. The manufacturer of the 12V2A power adapter tells you that these two components themselves have power consumption, and their attached voltage stabilizing circuit is naturally no exception, so the power supply itself is also a consumer.

The manufacturer of the 12V2A power adapter tells you that the energy of the input power cannot be 100% converted into the effective energy used by the components in the host. This is the problem of conversion efficiency we are talking about today.
The manufacturer of the 12V2A power adapter tells you that the conversion efficiency is an important indicator of the power adapter. High efficiency means that the less loss of the power adapter itself, the more energy is saved. The conversion efficiency of the power adapter is the total output power divided by the total input power, which is defined as efficiency.
The 12V2A power adapter manufacturer tells you that the relationship between the conversion efficiency and temperature rise of the power adapter has to be discussed here. Because the power adapter needs to lose the corresponding power inside the power adapter, the conversion efficiency of the power adapter cannot be 100%, and the power consumed by the power adapter is heated. The main effect of the heat generation of the power adapter itself depends on the conversion efficiency of the power adapter and the volume of the power adapter. The manufacturer of the 12V2A power adapter tells you that under certain heat dissipation conditions, the power adapter has a certain temperature rise, that is, the case temperature and the size of the power adapter. The difference in ambient temperature. The size of the heat dissipation surface of the power adapter shell directly affects the temperature rise. For places with higher temperatures, the power adapter needs to be derated to reduce the power consumption of the power adapter, thereby reducing the temperature rise and ensuring the power supply The temperature of the components of the adapter does not exceed the limit value. The manufacturer of the 12V2A power adapter tells you that in addition to meeting the requirements of electronic and electrical work, when the output power of the power adapter is constant, the temperature rise of the power adapter has a great impact on its mean time between failures, high efficiency, and low temperature. Liter makes the product longer life, volume and mass. When it comes to volume, we need to talk about power density.
The 12V2A power adapter manufacturer tells you that most power adapter manufacturers use the power density of the product as a standard to measure the effectiveness of the product. The 12V2A power adapter manufacturer tells you that if you cannot use the power adapter within the specified maximum ambient temperature range, it is possible The maximum output power of the parameter is not reached. The average output power available for the power adapter is the available power density.
