    Tips: Precautions of Desktop AC Adapter?

    What do the nominal voltage and current of the power adapter mean? First of all, the nominal voltage of the general power supply refers to the open circuit output voltage, that is, the voltage when no load is connected to the outside and there is no current output, so it can also be understood that this voltage is the upper limit of the output voltage of the power supply. In the case of an active voltage regulator component used in the power supply, even if the mains voltage fluctuates, its output is a constant value. Like a general small transformer on the market, such as a power supply such as a walkman, if the mains fluctuates, the output of the power supply will not fluctuate accordingly.

    Generally speaking, the true no-load voltage of an ordinary power adapter may not be exactly the same as the nominal voltage, because the characteristics of the electronic components cannot be completely consistent, so there is a certain error. The smaller the error, the higher the consistency of the electronic components.

    In addition, regarding the nominal current value, no matter any power supply has a certain internal resistance, when the power supply outputs current, it will generate a voltage drop internally, causing two things. One is generating heat, so the power supply will be hot, and the other one is to cause the output voltage to decrease, which is equivalent to internal consumption.
