Abstract

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.
