Abstract

An energy supply device for supplying electric power to a consumer of a vehicle has an input for establishing a connection to an on-board network of the vehicle in order to provide an input voltage for a transmission arrangement, an output for outputting a supply voltage to operate the consumer, a transmission arrangement for purposes of transmitting electric energy between the input and the output, whereby the transmission arrangement comprises a signaling adaptation means, so that, as a function of a deviation of the input voltage that is critical for the electric power supply, a signal is impressed upon the supply voltage, whereby the signal can be evaluated in the consumer on the basis of the supply voltage.
