Abstract
An improved system and method measuring a temperature in a power controller is provided. The system includes a circuit board, a solid state switching device, a heat sink, and a temperature sensor. The solid state switching device may be mounted on the circuit board and controls the switching of power to an industrial load. The heat sink is mounted on the solid state switching device such that a first portion of the heat sink is thermal communication with the solid state switching device and a second portion of the heat sink is in thermal communication with an exposed portion of a trace on the circuit board. The temperature sensor may be in thermal communication with the trace. As such, the temperature sensor may be in thermal communication with the solid state switching device through the trace of the circuit board.
