Abstract
A field device for an industrial process includes field device circuitry, an APL communication circuit, and a power circuit. The power circuit includes a power regulator configured to regulate DC power that powers the field device circuitry and the APL communication circuit, a main power sensor configured to generate a main power signal that corresponds to the DC power, a voltage shunt regulator configured to divert excess power to a circuit common, and an excess power sensor configured to generate an excess power signal that corresponds to a magnitude of the excess power. The power regulator adjusts the DC power based on the main power signal and the excess power signal.
