Abstract:
1. A power supply apparatus, which supplies power to an equipment via a cable, comprising: a power receiving section that receives supply of the power from a power line; a power line communicating section that transmits a communication signal to the equipment via the cable; a power supply limiting section which is installed between the power receiving section and the equipment, allows the communication signal from the power line communicating section to pass to the equipment, and limits the supply of the power to the equipment; a power supplying section which is installed between the power receiving section and the equipment and passes the power to the equipment; a connecting section to which the equipment is connected and which supplies the power to the equipment; a voltage detecting section that detects a voltage of the connecting section; a control section that controls passage of the power by the power supplying section, if reduction of the voltage of the connecting section is detected by the voltage detecting section; and a storage section that stores registered information of the equipment; wherein the power line communicating section performs communication with a second power line communicating section of the equipment, and performs authentication processing whether or not the equipment is registered in the registered information, and transmits a control signal to the control section to enable passage of the power by the power supplying section if identification information from the second power line communicating section corresponds to the registered information.
