spänningsvalfunktion

A spänningsvalfunktion, or voltage selection function, is a component or mechanism within an electronic device that allows a user or the system to choose from a range of input or output voltage levels. This is often implemented to accommodate different power sources, regional electrical standards, or specific operational requirements of the device. For example, a universal power supply might incorporate a spänningsvalfunktion to accept either 110V or 220V AC input, automatically adjusting its internal circuitry to match the incoming voltage.

The function can manifest in various forms. It might be a physical switch, such as a small slider or a rotary dial, clearly labeled with different voltage options. In more advanced or integrated systems, the spänningsvalfunktion could be software-controlled, with the device detecting the input voltage and configuring itself accordingly, or allowing the user to make selections through a digital interface. The primary purpose is to ensure the device operates safely and efficiently by providing the correct voltage for its internal components. Without a proper spänningsvalfunktion, attempting to power a device designed for a lower voltage with a higher voltage supply could lead to damage or destruction.
