1. A power distribution unit comprising:

  • a plurality of switched power outlets adapted to provide power to external devices wherein the switched power outlets are adapted to be controlled by a control signal;

    a sensor that measures the magnitude of the current of power being drawn by the power distribution unit;

    a comparator that determines if the magnitude of the current exceeds a predetermined threshold;

    time qualification circuitry that determines if the magnitude of the current exceeds the predetermined threshold for a predetermined time duration; and

    control circuitry that sends a control signal to said switched power outlets when the magnitude of the current exceeds a predetermined threshold for a predetermined time duration.
