Abstract

An electronic power management system includes at least one power distribution unit, a control panel, and at least one data bus. The power distribution unit distributes electrical power to at least one electric load and provides status of each electrical load and characteristics of the electrical power. The control panel receives the status and electrical power characteristics and controls operation of the electrical loads in response to the status and electrical power characteristics. The data bus communicatively couples the control panel and the power distribution units. The electrical characteristics for each load include measured electric current and voltage values, and an indication as to whether measured values are over, under, within a range, or out of a range of threshold values.
