Abstract
A power management apparatus including a peripheral control circuit, an input switching circuit and an output control circuit is provided. The peripheral control circuit communicates with a remote device and provides a control signal and switching signals accordingly. The input switching circuit detects AC powers, and selects one of the AC powers as a supply power according to the control signal. When the selected AC power fails, the input switching circuit selects the other AC power as the supply power within a predetermined time duration. The output control circuit receives the supply power and is controlled by the switching signal to provide output powers to external loads. The output control circuit detects power utilizing information of the external loads. The remote device obtains power statuses of the AC powers and the power utilizing information of the external loads via the peripheral control circuit to monitor the power management apparatus.
