Abstract
A bus instrument () configured to predictively limit power consumption and adapted for use with a two-wire instrumentation bus is provided. The bus instrument () includes a sensor (), a shunt regulator (), and a controller (). The controller () is configured to generate a predicted available power Pthat will be available to the bus instrument () after a change in the loop current I, compare the predicted available power Pto a present time power Pcomprising a controller power Pplus a sensor power P, and reduce the sensor power Pif the total available power Pis less than the controller power Pplus the sensor power P.
