摘要
A circuit arrangement with a power input and at least one power supply unit that generates a DC voltage for operating an electronic device including a power input circuit inserted between the power input and the at least one power supply unit that selectively disconnects or rectifies an AC voltage provided via the power input for the at least one power supply unit, wherein the power input circuit has at least one first semiconductor switching element that switches a first electrical load path with a current limiting element from the power input to the at least one power supply unit, and at least one second semiconductor switching element that switches a second electrical load path from the power input to the at least one power supply unit, and a power input filter, wherein the power input filter includes a first filter circuit arranged between the power input and the power input circuit and a second filter circuit arranged between the power input circuit and the at least one power supply unit.
