An electrical supply module including a composite board including a first and a second layer of an electrically conducting material separated by an insulator, which first layer forms an outer surface including a first electrical contact site, the composite board having a recess, allowing access to a second electrical contact site at the second layer, the recess having a coupling portion and a coupling unit having a complementary coupling portion allowing releasable coupling with the coupling portion of the recess, a first electrical contact area and a second electrical contact area, wherein coupling of the coupling portion and the complementary coupling portion establishes electrical connection from the first and second electrical contact sites to the first and second electrical contact areas, respectively. The electrical supply module provides a flexible device that allows freely adding and removing various electronic components to the composite board.

A power distribution system includes a panel assembly that has an outer surface and two conductive structures spaced from each other and spanning beneath the outer surface. An application module is configured to engage one of a plurality of locations disposed over the outer surface of the panel assembly. The application module includes a first contact configured to engage the first conductive structure and a second contact configured to engage the second conductive structure. The second contact is electrically insulated from the first contact and the first conductive structure for the panel assembly to deliver low voltage power to the engaged application module.

The low voltage power distribution bus system for a plurality of connected modules includes an intelligently managed power load. The system maintains a marginal reserve of power while monitoring the amount used of the total power. When a new module is connected, a base power setting for the new module is retrieved. The system calculates available power and compares the base power setting. If the available power is exceeded, the system redistributes a maximum allowed power of each connected module and assigns the new module an allowed maximum power. The allowed maximum power is the base power setting if the available power exceeds the base power setting of the new module and a fraction of the base power setting if the base power setting of the new module exceeds the available power.
