An AC/DC power supply is a device that converts alternating current (AC) into direct current (DC), delivering stable power to a wide range of electronic devices and systems. These power supplies are commonly used in electronic design, testing, and repair—especially in applications that require stable DC voltage.

1. Voltage Conversion：Converts AC input into the required DC output voltage.
2. Adjustable Output：Provides variable voltage output to meet the needs of different devices and test conditions.
3. Overcurrent Protection：Prevents excessive current from damaging the power supply or connected devices.
4. Voltage Regulation：Maintains a consistent DC output even when the input voltage fluctuates.​

    Common types of AC/DC power supplies include benchtop models, modular units, and laboratory-grade supplies. The appropriate type is selected based on specific application requirements such as form factor, output range, and load conditions.
