Abstract
A power supply according to various embodiments of the disclosure is configured to detect an event and, in response to the event, alternately supply power to a plurality of provided devices via a provided bus at a first current level or at a second current level, the second current level less than the first current level. Among other things, embodiments in this disclosure help allow additional devices to be used on a bus, even where the total power consumption of the devices would normally exceed a maximum defined by a bus architecture. Furthermore, various embodiments help allow a single gauge of wire to be used throughout a bus network (even where long lengths of wire are required) while still providing sufficient power to the devices connected to the bus.
