A power supply system includes a power source and a control circuit. The power source provides DC power. A control circuit, which is remote to the power source, receives the DC power and provides a first DC power signal to an electronic device. The control circuit includes an active component to provide at least one of a voltage control output or a current control output to the power source to regulate the DC power.
