Abstract: The Power Supply Unit comprises an output providing electrical power between a positive power supply line and a common ground line and a communication line. An adjustable current generator responsive to an internal measurement signal generates an output current at the output, and a voltage source is coupled to the communication line. A current measurement unit measures a current through the communication line and generates the internal measurement signal depending on the measured current through the communication line. Specifically, the Power Supply Unit is configured to determine the voltage drop on the common ground line by applying via the voltage source two different voltages to the communication line.
