Abstract: A power control system for use with an electric lock mechanism including an actuator having a coil with a particular coil impedance. 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.

Abstract: A power control system for use with an electric lock mechanism having an actuator comprises a power supply to output an output voltage to the actuator. A credential device signals the power supply to output the voltage upon receiving an authorized code. A microcontroller controls the power supply, the credential device, and the actuator and may operate in an Access Mode or a Dog Mode. When in Access Mode, the actuator is unpowered and the credential device is powered until an authorized code is received and the power supply powers the actuator. The Dog Mode has an awake mode where the actuator is powered and the credential device is unpowered after the actuator remains in the powered state for a length of time. A sleep mode has the actuator unpowered and the credential device powered until an authorized code is received and the power supply powers the actuator.

Abstract: A power control circuit assembly for an electric door lock comprises a load control circuit module configured to distribute a DC operating voltage to power an electromechanical door latch mechanism and its associated access control device. An energy storage device such as a rechargeable battery is coupled to the load control circuit module and is configured to deliver a DC voltage to the load control circuit module wherein the DC energy storage device voltage supplies the DC operating voltage. A rectifier is configured to receive an input AC voltage and convert the input AC voltage to an input DC voltage. The input DC voltage is adapted to deliver an energy storage device recharge voltage. An energy storage device voltage detection module is configured to interrogate a DC voltage supplied by the energy storage device.
