FIELD: electrical engineering.
SUBSTANCE: invention relates to a device for supplying power to a powered device via a wire data line. Device is configured to supply power to the device to be powered in accordance with the configuration, installed on at least one parameter transmitted by the device being powered by a wire line of data transmission in the power supply cycle. Besides, device comprises memory for storage of configuration information and controller for device control based on stored information, in order to supply power in accordance with the same configuration to the power supply device in the next power cycle after power disconnection.
EFFECT: technical result consists in provision of possibility of accelerated commissioning of the powered device after power supply interruption along the data transmission line by means of the device connected to the supplied device.
