Automatic circuit allocation of remote devices in a multi-power supply system

A centralized power supply system comprising a controller coupled to a first set of DC power supply units, wherein:

• (a) each DC power supply unit of the first set of DC power supply units is configured to be capable of:
• (i) being electrically connected to a respective power cable of a first set of a plurality of power cables;
• (ii) transmitting a power signal to a respective remote device of a first set of a plurality of remote devices via the respective power cable;
• and
• (b) the controller is configured to perform the steps of:
• (i) sending one or more voltage instructions to one or more DC power supply units of the first set of DC power supply units to set a respective predetermined voltage for each of the one or more DC power supply units;
• (ii) sending a first power modification instruction to a first DC power supply unit of the first set of DC power supply units to modify an output voltage of the first DC power supply unit over a first power cable of the first set of the plurality of power cables,
• (iii) receiving a plurality of input voltage values associated with each of the first set of the plurality of remote devices including a first input voltage value associated with a first remote device of the first set of the plurality of remote devices;
• (iv) comparing the respective input voltage value of each remote device of the first set of the plurality of remote devices and determining that the first input voltage value differs by more than a predetermined value from the input voltage value of each other remote device of the first set of the plurality of remote devices;
• and
• (v) automatically assigning a correspondence between the first DC power supply unit and the first remote device.
