Abstract

Abstract An apparatus for and method of managing and distributing power from a supply of limited power is described. A plurality of outlets are connect to a plurality of power units. As additional outlets are used, the invention measures the amount of power drawn by the outlets. Outlets are enabled if the amount of measured power is less than a maximum amount of power available. Additional outlets not currently in use are disabled if the amount of measured power is greater than the maximum amount of power available.
