1. A distributed communications system (DCS), comprising:
a central unit configured to:
distribute one or more downlink communications signals over one or more downlink communications links to a plurality of remote units; and
distribute received one or more uplink communications signals from the plurality of remote units from one or more uplink communications links to one or more source communications outputs;
the plurality of remote units, each remote unit among the plurality of remote units configured to:
distribute at least one received downlink communications signal among the one or more downlink communications signals from the one or more downlink communications links, to one or more client devices; and
distribute the or more uplink communications signals from the one or more client devices to the one or more uplink communications links; and
a power distribution circuit, comprising:
a source power management circuit (PMC) comprising:
a source power input;
a source current limiter circuit coupled to the source power input and a source power output;
the source PMC configured to receive source current of a source power on a source power input from a power source;
the source current limiter circuit configured to limit the source current to a source current threshold limit to generate a limited source current; and
the source PMC further configured to distribute the limited source current on the source power output;
a plurality of remote PMCs each comprising:
a remote power output coupled to a remote unit among the plurality of remote units;
each of the plurality of remote PMCs configured to:
receive a remote current on a remote power input coupled to the source power output based on the limited source current; and
distribute the remote current to the remote unit coupled to the remote power output; and
an energy storage circuit coupled to source power output, the energy storage circuit configured to:
store energy from the limited source current on the source power output in response to a current demand by the plurality of remote PMCs being less than the source current threshold limit.
