Power supply

maker

A device that provides electrical power to an electrical load, converting from one form of energy to electrical energy.

expanded

A power supply unit (PSU) is critical in providing consistent electrical power tailored to the needs of electronic devices, often converting AC current from a mains source to the specific DC voltages necessary for internal components. This conversion is essential in electronic circuits found in a variety of applications from consumer electronics to industrial machinery, thereby facilitating reliability and functionality of these devices.

examples

ATX power supplies deliver +3.3V, +5V, +12V DC outputs, commonly used in personal computers.

Typically utilized in desktop computers to power the CPU, motherboard, and peripherals, adhering to the ATX12V standard.

A 24V DC power supply used for 3D printers provides the required power for motors and heating elements.

Employed in various 3D printers to ensure stable output, crucial for precise operational control and consistent performance.
