A power distribution arrangement comprising an input connected to a power source, two or more outputs each adapted to be connected to one of a multiplicity of loads (2, 3, 4, 5), at least one power limiting unit (8, 9) connected between the input and a respective one of the outputs and receiving a corresponding threshold (at 15), which represents the value to which the amount of power provided to the respective one of the outputs is to be limited, and a power management unit that provides the threshold/s (at 15) to the at least one power limiting unit (8, 9) and that is configured to evaluate a total power currently supplied by the power source, and to set the threshold/s (at 15) based on the difference between the total power currently supplied by the power source and a maximum power of the power source; wherein each power limiting unit (8, 9) comprises: a power sensor that is connected between the input and the particular one of the outputs and adapted to measure a representation of the power supplied by the power source to the respective load (3, 4) connected to the particular one of the outputs; a power circuit that is connected in series to the power sensor and that supplies, dependent on a control signal (at 22), a regulated output voltage or a regulated output current or both to the respective load; the power circuit comprises a control element receiving the control signal (at 22); a comparison unit that is coupled to the power sensor to receive the measured representation of the power supplied to the particular one of the outputs and that compares the representation to the corresponding threshold (at 15) for providing an overload signal in case the representation exceeds the corresponding threshold (at 15); and a control unit that is connected to the comparison unit for receiving the overload signal and to the power circuit for limiting the control signal (at 22) to a value such that an output power of the power circuit is limited to the amount of power indicated by the respective threshold (at 15), when the overload signal occurs. an input connected to a power source, two or more outputs each adapted to be connected to one of a multiplicity of loads (2, 3, 4, 5), at least one power limiting unit (8, 9) connected between the input and a respective one of the outputs and receiving a corresponding threshold (at 15), which represents the value to which the amount of power provided to the respective one of the outputs is to be limited, and a power management unit that provides the threshold/s (at 15) to the at least one power limiting unit (8, 9) and that is configured to evaluate a total power currently supplied by the power source, and to set the threshold/s (at 15) based on the difference between the total power currently supplied by the power source and a maximum power of the power source; a power sensor that is connected between the input and the particular one of the outputs and adapted to measure a representation of the power supplied by the power source to the respective load (3, 4) connected to the particular one of the outputs; a power circuit that is connected in series to the power sensor and that supplies, dependent on a control signal (at 22), a regulated output voltage or a regulated output current or both to the respective load; the power circuit comprises a control element receiving the control signal (at 22); a comparison unit that is coupled to the power sensor to receive the measured representation of the power supplied to the particular one of the outputs and that compares the representation to the corresponding threshold (at 15) for providing an overload signal in case the representation exceeds the corresponding threshold (at 15); and a control unit that is connected to the comparison unit for receiving the overload signal and to the power circuit for limiting the control signal (at 22) to a value such that an output power of the power circuit is limited to the amount of power indicated by the respective threshold (at 15), when the overload signal occurs.
