Power supplies are devices or hardware that convert or transform electrical input into electrical output. A power supply can be located both internally and externally depending on the need and application. They may be used to change an AC input voltage to DC output voltage, a DC input voltage to a different DC output voltage, or an AC input voltage to a different AC output voltage. All power supplies are used to provide a desired output voltage and are available in a variety of types and functionalities.

Types: The most common power supply types include AC/DC power supplies, DC/DC converters, switching power supplies, linear power supplies, uninterruptible power supplies (UPS), enclosed power supplies, DIN rail power supplies, and programmable power supplies, each designed for specific power conversion and distribution requirements.

Applications: Power supplies are widely used in industrial equipment, consumer electronics, telecommunications systems, computers, test and measurement devices, and embedded systems to deliver reliable and stable power.

Selection requirements: Choosing a power supply requires evaluating input/output voltage and current, power rating, efficiency, form factor, thermal performance, and protection features to ensure compatibility and reliability in the intended application.
