ACSeite
ACSeite is a term used in electrical engineering, especially in German-speaking contexts, to describe the portion of a device or circuit that is connected to alternating current (AC). The counterpart is the DC-Seite, referring to the direct-current side, usually after rectification or conversion. In schematic diagrams, the ACSeite is typically labeled with AC symbols (such as ~) and denotes the input section of a power supply or similar equipment.
In practice, the ACSeite includes components and circuits involved with acquiring the mains supply or other
Design and safety considerations are prominent for the ACSeite. Designers must ensure electrical isolation where required,
The boundary between ACSeite and DC-Seite varies by design. In some layouts the rectifier marks the division,
