1. A distributed low voltage power system, comprising:

  • a power source generating line voltage power;

    a first line voltage cable comprising a first line voltage end and a second line voltage end, wherein the first line voltage end is coupled to the power source;

    a first power distribution module (PDM) comprising a first power transfer device, wherein the second line voltage end of the first line voltage cable is coupled to the first PDM, wherein the first PDM receives input power from the power source through the first line voltage cable, wherein the first power transfer device generates a first low-voltage (LV) signal from the input power, and wherein the first PDM comprises a first output channel;

    a first communication link coupled to the first output channel of the first PDM;

    a first point-of-load (POL) control device of a plurality of POL control devices coupled to the first PDM, wherein the first POL control device is coupled to the first output channel of the first PDM using the first communication link, wherein the first POL control device generates at least one first distributed LV signal based on the first LV signal received from the first PDM; and

    at least one first LV device coupled to the first POL control device, wherein the first POL control device sends the at least one first distributed LV signal to the at least one first LV device, wherein the first LV signal sent by the first PDM is specifically addressed to the first POL control device and the at least one first LV device, wherein the at least one first distributed LV signal provides power regulation to the at least one first LV device, and wherein only the first POL control device of the plurality of POL control devices executes instructions of the first LV signal.
