Abstract:
1. A power distribution system comprising an input connected to a power source, a plurality of outputs, each output connected to one of a plurality of loads, and at least one power limiting unit connected between the input and one of the outputs, the power limiting unit comprising: a power sensor connected between the input and each of the plurality of outputs, that measures the power supplied by the source to the plurality of loads; a plurality of power circuits each connected in series to the power sensor, and supplies a regulated electrical output to a respective one of the plurality of loads, each of the plurality of power circuits comprising a control element that receives a control signal; a comparison unit coupled to the power sensor to receive a measured representation of the power supplied to a particular one of the plurality of outputs, and compare the measured representation to a threshold for providing an overload signal in case the measured representation exceeds the threshold; and a control unit connected to the comparison unit for receiving the overload signal and each of the plurality of the power circuits for providing the uniquely associated control signal and limiting the associated control signal to a given value in case the overload signal is received.
