Abstract
An intermediate power supply unit for distributing lower voltage power to remote devices is disclosed. The intermediate power supply unit includes a higher voltage power input configured to receive power distributed by a power source and a power coupling circuit configured to couple the higher voltage power input to a plurality of power coupling outputs. If it is determined that a wire coupling the power source to the higher voltage power input is touched, the higher voltage power input is decoupled from the power coupling outputs. The intermediate power supply unit also includes a power converter circuit configured to convert voltage on higher voltage inputs to a lower voltage applied to one or more lower voltage outputs. The power converter circuit is also configured to distribute power from the one or more lower voltage outputs over a power conductor coupled to an assigned remote device.
