ABSTRACT:
A first resistor is connected in parallel with a second resistor having a lower resistance than the first resistor. The voltage at the terminal of the first resistor is compared with a first threshold voltage, and the voltage at the terminals of the second resistor is compared with a second threshold voltage. A switching device either connects the first resistor in series in a remote power feed circuit, if the switching device detects that the remote power feed current is less than a third threshold current that is between the first and second threshold currents, or connects the second resistor and the first resistor, connected in parallel, in series in the remote power feed circuit if the switching device detects that the remote power feed current is greater than the third threshold current.
