Abstract

A method for identifying at least one electrically powered device by a power supply device via a powerline connection, includes: a) connecting the at least one electrically powered device via a powerline to core power supply; b) sensing that a powerline connection is available by the at least one electrically powered device; c) generating a specific load by modulation of the power according to a unique identifier of the at least one electrically powered device on the powerline connection; d) sensing the generated specific load by the power supply device connected to the powerline connection; and e) extracting the unique identifier information from the specific load by the power supply device. An electrically powered device, a power supply device, a power distribution unit, and a corresponding system are also described.
