Abstract

Disclosed is a power distribution unit and power management architecture employing such power distribution unit. The power management architecture includes a remote power management system for managing a plurality of power appliances, and a plurality of power distribution units each of which is provided with wireless network connectivity. With the wireless network connectivity, the remote power management system and the power distribution units constitute a mesh link network for two-way data transmission. In operation, the remote power management system transmits a first profile to the power distribution units to allow the first control unit of the power distribution unit to real-timely control the operation of the power distribution units according to the management policy and/or the management principle recorded in the first profile.
