Zasilany

Zasilany is a Polish adjective meaning "powered" or "supplied with energy." It is commonly used in technical and everyday language to describe devices, systems, or components that receive energy from an external source rather than generating it themselves. The term is formed from the verb zasilać (to power or feed) and the passive participle suffix -any; its related noun is zasilanie, referring to the act or system of supplying power.

In engineering, electronics, and manufacturing, zasilany distinguishes equipment that requires an external power source from passive or self-powered devices. Examples include urządzenie zasilane z sieci (mains-powered device) and urządzenie zasilane baterią (battery-powered device). The expression may appear in product descriptions, manuals, and safety labels to indicate how a device obtains energy.

Zasilany can also describe subsystems within larger configurations, specifying their energy input method, such as zasilany ze źródła odnawialnego (powered by a renewable source). The term often implies dependence on its power source and can be contrasted with terms like bez zasilania (unpowered) or samozasilający (self-powered), depending on context.

In various domains, references to zasilany are accompanied by more precise qualifiers, for example zasilany prądem stałym (DC-powered) or zasilany prądem zmiennym (AC-powered). Related concepts include zasilanie (power supply), zasilacz (power supply unit), and źródło zasilania (power source).
