AC/DC adapters are commonly used external power supply units for electrical equipment which cannot directly draw power from the mains network. They convert alternating current (AC) into the required direct current (DC).
Typically, such devices do not have space within their casing for the bulky components required for this conversion. Swappable external power supply units also provide more flexibility.
Phone and laptop chargers are perhaps the most familiar form of AC/DC adapter. However, they also have a variety of uses in industrial settings - for example, they are used with motors and automation equipment.
AC/DC adapters have many alternative names, including:
- AC DC adapters
- AC/DC converters
- AC chargers
- DC adapters
- AC adapters
- AC adapter plugs
- Battery chargers
- Switching adapters
- Plug-in power supplies
- Power adapters
