CONTROLLER CIRCUIT INCLUDING A SWITCH MODE POWER CONVERTER AND AUTOMATIC RECLOSER USING THE SAME

摘要

An autorecloser circuit including a relay circuit with an electromagnetic relay configured to be coupled between an AC power source and a customer location to deliver current from the AC power source to the customer location. A controller coupled to the relay circuit is configured to control the electromagnetic. A current sense circuit coupled to the controller is configured to detect an amount of the current that is delivered to the customer location and a reference voltage circuit coupled to the controller is configured to establish a reference level for the amount of the current that is delivered to the customer location. A power circuit coupled to the controller and to the relay circuit is configured to provide a DC power source to the controller and to the relay circuit from the AC power source. The controller is configured to disconnect or reconnect the AC power source from the customer location based on the detected amount of current.
