The power control system comprises a power supply configured to provide an output voltage having a drive current to the actuator, a credential device powered by the power supply and configured to signal the power supply to provide the output voltage upon receiving an authorized access code, an actuator driver including a multiple-gain current-sensing circuit, and a microcontroller configured to monitor and control the power supply, credential device, actuator driver, and actuator, and determine the impedance of the coil. The microcontroller is populated by a look-up table having performance data for a plurality of coils such that the microcontroller selects a duty ratio to establish the optimum magnitude of drive current to the coil based only on the determined impedance of the coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power controller for a door lock and method of conserving power","description":"A power control system for use with an electric lock mechanism including an actuator having a coil with a particular coil impedance.
