Abstract
A system for precisely controlling the operational characteristics of a relay is provided. In one embodiment, the invention relates to a relay having performance characteristics that vary with a temperature of the relay, where the relay comprises a plurality of operational phases including a switching phase and a holding phase, and a relay control circuit configured to provide a preselected current to the relay at least during the switching phase and the holding phase, where the preselected current remains substantially constant despite a change in the temperature of the relay, where the relay is configured to transition from a non-energized position to an energized position during the switching phase, and where the relay is configured to maintain the energized position during the holding phase.
