Input Source: The power supply receives electrical energy from an external source, such as an electrical outlet, battery, or solar panel.
Conversion: It converts the input power into a usable form, which can be direct current (DC) or alternating current (AC), depending on the requirements of the connected device.
Regulation: The power supply regulates the output voltage and current to ensure they remain stable and within the specified range, even if the input voltage fluctuates.
Protection: It may include protective features such as overcurrent protection, overvoltage protection, and short-circuit protection to safeguard both the power supply and the connected device.
