ABSTRACT:
Power sourcing equipment providing a plurality of power sources for connection over communication cabling to a single powered device, the power sourcing equipment comprising: a first power source; a second power source; a control circuit; a current sensor adapted to monitor an output current of the first power source, the current sensor being operatively connected to the control circuit; and a voltage regulating means associated with one of the first power source and the second power source, the voltage regulating means being responsive to the control circuit, the control circuit being operative responsive to the monitored output current to operate the voltage regulating means so as to maintain the monitored output current within a pre-determined range.
