DCsyötöistä

DCsyötöistä refers to direct current power supplies. These are devices that convert alternating current (AC) from the mains power grid into direct current (DC). Many electronic devices, such as computers, smartphones, and various appliances, require DC power to operate. A DC power supply, often called an AC/DC adapter or power brick, contains a transformer to reduce the voltage, a rectifier to convert AC to pulsating DC, and filters and regulators to smooth and stabilize the DC output. The output voltage and current are specific to the device the power supply is designed for. Improperly matched DC power supplies can damage electronic equipment.
