摘要： A control circuit for an energy saving contactor including at least one power contact is provided. The control circuit includes a power supply unit, an energy storage circuit coupled to the power supply unit, a first transducer coupled to the power supply unit and configured to switch the at least one power contact from an open armature position to a closed armature position, a latch system configured to maintain the at least one power contact in the closed armature position, a second transducer coupled to the power supply unit and configured to disengage the latch system to cause the at least one power contact to switch from the closed armature position to the open armature position, and a controller configured to control electrical power supplied from the power supply to the first and second transducers to selectively activate the first and second transducers based on monitored input voltage conditions.
