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.

AC-DC Power Supply Converts AC mains input (110V/220V) into regulated DC output voltage. The most common type used in industrial equipment, consumer electronics, and embedded systems. Available in open-frame, enclosed, and DIN rail-mount formats.

DC-DC Converter Takes a DC input voltage and converts it to a different DC output voltage, either higher (boost), lower (buck), or inverted. Widely used on PCBs to supply multiple voltage rails from a single power source, common in telecommunications, automotive, and portable devices.

AC-AC Power Supply Converts one AC voltage level to another AC voltage level, typically using a transformer. Used in voltage adapters, isolation applications, and equipment requiring a different AC voltage than the local mains supply.

Linear Power Supply Uses a linear regulator to drop excess voltage as heat, producing a clean, low-noise DC output. Preferred in audio equipment, laboratory instruments, and sensitive analog circuits where output ripple and noise must be minimized.

Switched-Mode Power Supply (SMPS) Uses high-frequency switching to convert and regulate power with high efficiency (typically 85–95%). Compact and lightweight compared to linear supplies. The dominant power supply technology in modern electronics, from laptop adapters to industrial machinery.

Uninterruptible Power Supply (UPS) Provides backup power from a battery when the main power source fails. Protects critical equipment such as servers, medical devices, and industrial control systems from power outages, voltage sags, and surges.

Programmable Power Supply Allows output voltage and current to be adjusted remotely via software or front-panel controls. Used in R&D labs, automated test equipment, and production line testing where flexible, precise power output is required.

DIN Rail Power Supply Designed to snap onto standard DIN rails inside electrical cabinets. Converts AC mains to regulated DC (typically 24V or 48V) for powering PLCs, sensors, and control equipment in industrial automation systems.
