ABSTRACT:
A method and apparatus for power reduction in the operation of a power circuit for a relay or other electro-mechanical device having a first (higher) power requirement for the device to be activated, and a second (lower) power requirement for the device to be maintained includes charging a power supply capacitor to the necessary voltage for the first power requirement while the device is not activated, supplying current from the power supply capacitor to the device when it is activated until the voltage reaches the second power requirement, and keeping the power supply capacitor voltage at that second power requirement to maintain activation of the device.
