What does the nominal voltage and current of the power adapter (hereinafter referred to as the power supply) mean? First of all, the nominal voltage of the general power supply refers to the open-circuit output voltage, that is, the voltage when there is no external load and no current output, so it can also be understood that this voltage is the upper limit of the power supply output voltage.
In the case of active voltage stabilizing elements used in the power supply, even if the mains voltage fluctuates, its output is also constant. If the mains voltage fluctuates, the output of the power supply will not fluctuate with it, such as the small transformer on the market, such as the power supply equipped with a walkman.Keywords:
