1. A power strip, comprising:

  • a housing having a first end and a second end;

    at least one power outlet mounted on an exterior surface of the housing;

    a power management circuit defined on an interior region of the housing, including;

    a micro-controller coupled to the power supply and to a relay driver, the relay driver receiving control signals from the micro-controller;

    an input power source sensor circuit is coupled intermediate the power supply and the micro-controller, to receive primary input power from the power supply and secondary input power from a secondary power source, whereby the input power source sensor circuit provides the primary input power to the micro-controller and if the primary input power fails, the input power source sensor circuit provides the secondary input power to the micro-controller; and

    at least one relay coupled to the relay driver and to the at least one power outlet,wherein the relay receives a control signal from the relay driver to actuate the relay to a conductive state to powering-on the power outlet and the relay receives another control signal from the relay driver to actuate the relay to a non-conductive state to powering-off the power outlet; and

    an under voltage sensor coupled to the micro-controller and adapted to receive a predetermined voltage value from the power supply,wherein the micro-controller is configured to indicate that current from the power supply has exceeded a predetermined threshold value.
