An apparatus for generating a power signal from a load current is described, has a controller with a load current input, a load current output, an intermediate signal output, and a status signal output, an influencing device with an intermediate signal input and a power signal output, and an interruption device with an interrupt input, an interrupt output, and a status signal input. The controller generates a status signal and an intermediate signal depending on the load current, and the interruption device interrupts the power signal if the status signal satisfies a predetermined first condition, and otherwise lets the power signal pass, and the influencing device generates the intermediate signal as the power signal and output the same at the power signal output if the intermediate signal does not satisfy a predetermined second condition, and otherwise generates and output a power signal with a predetermined value.
