virtalähteellään

virtalähteellään is a Finnish word that translates to "with its power source" or "by its power source" in English. It is a possessive form of the noun virtalähde, which means power source or power supply. The suffix -llään indicates the third-person possessive with the adessive case, meaning "on/at/with him/her/it/them". Therefore, virtalähteellään refers to something being powered by or connected to its own power source.

This term is commonly used in technical contexts, such as electronics, engineering, and computing. For example, a device operating virtalähteellään means it is functioning independently of an external power grid, relying solely on its internal battery or other self-contained power unit. Similarly, a system described as virtalähteellään installed might imply it has its own dedicated power supply unit, separate from the main building's electrical system. The specific meaning can vary depending on the context, but the core idea remains the presence of an intrinsic power provision.
