The invention relates, among other things, to an assembly (10), comprising a potential-isolated electrical power supply device (20), which electrical power supply device has: an input (E20) for applying an input voltage, an output (A20) potential-isolated from the input for outputting an output voltage, and a control connection (S20), at which a control signal (ST) for increasing or lowering the output voltage can be applied, and comprising a control device (30), which is connected to the control connection (S20) of the electrical power supply device (20) and can apply the control signal (ST), and comprising a voltage evaluating module (40), which is connected to the control device (30) and to the output (A20) of the electrical power supply device (20) and supplies a feedback signal (Srk) concerning the voltage level of the output voltage to the control device (30). According to the invention, the control device (30) is suitable for alternatively setting one of at least two different target voltage levels at the output (A20) of the electrical power supply device (20), the voltage evaluating module (40) is designed in such a way that the voltage evaluating module sends a feedback signal (Srk) back to the control device (30), by means of which feedback signal the overshoot or undershoot of each of the at least two different target voltage levels at the output (A20) of the electrical power supply device (20) is indicated by means of a signal change of the feedback signal (Srk), and the control device (30) is suitable for setting each of the at least two different target voltage levels at the output (A20) of the electrical power supply device (20) while taking into account the signal changes of the feedback signal (Srk). |
