Claim of US Patent No. 10,412,799

1. A powered device for being used in a power distribution system, the power distribution system comprising:a power providing device for providing a power at an output voltage to the powered device over a power output interface and for monitoring said power for occurrence of an overload condition, which occurs when said power corresponds to a predetermined second power limit, and
an electrical conductor for transmitting the power between the power providing device and the powered device;wherein the powered device is assigned to a power class corresponding to a predetermined first power limit and the predetermined second power limit, the predetermined first power limit relating to a maximum power that the powered device may consume and the predetermined second power limit relating to a maximum power that the power providing device of the power distribution system may provide; and w herein the powered device is arranged to indicate the assigned power class to the power providing device;the powered device comprising:a power input interface for receiving the power,
an electrical load, and
an electrical load power providing unit for transforming the power received over the power input interface into an electrical load power and for providing the electrical load power to the electrical load,
wherein the electrical load power providing unit is arranged for determining a current limit as a power control value based on the output voltage of the power provided over the power output interface by the power providing device of the power distribution system, and
wherein the electrical load power providing unit is further arranged to control the power level of the electrical load power based on the power control value to avoid the occurrence of the overload condition at the power providing device, such that the power consumed by the powered device is above the predetermined first power limit and the power provided by the power providing device is equal to or below, the predetermined second power limit.
