The present invention relates to an electrical supply apparatus and a device and an electrical power supply module. The apparatus comprises means of reception of a supply voltage originating from the supply module, having a higher voltage level in normal mode and at least one lower voltage level in standby mode, means of activation of at least one functionality of the apparatus, which are operational in normal mode and disabled in standby mode, and means of switching of the supply module toggling the supply voltage at least from the standby mode to the normal mode. The apparatus comprises means of communication to the supply module, including the means of switching, means of transmission of a current to the supply module and means of variation of intensity of this current, the means of communication controlling a toggling of the supply voltage at least from the standby mode to the normal mode through a variation of this current. By this manner, for controlling the supply voltage for receiving, the apparatus modulates the current provided by the supply module. The supply module detects the variation of intensity of the supply voltage, and according to these variations, defines a new supply voltage.
