Power Supply Unit (Psu)
A Power Supply Unit or PSU is a device that provides power to an electronic device. A PSU typically contains a transformer, rectifier and filter. The most common type of PSU is a AC-to-DC converter. PSUs are used in computers, cell phones and other electronic devices. A Power Supply Unit or PSU is a device that provides power to an electronic device.
A PSU typically contains a transformer, rectifier and filter. The most common type of PSU is a AC-to-DC converter. PSUs are used in computers, cell phones and other electronic devices. PSUs convert the alternating current (AC) from the mains supply into low voltage direct current (DC) required by the internal components of the electronic device. The DC voltage is then regulated to ensure that it remains constant despite changes in the AC mains supply voltage or load current demand from the electronic device components.
