Abstract

See full text

A system includes a contactor operatively connected to a coil for actuating the contactor to open and close a circuit. A pass element includes a source, a drain, and a gate, wherein the drain is electrically connected to the coil, and wherein the coil is in series between the pass element and ground. A voltage source is connected to the source of the pass element to pass current into the coil when the pass element is in a pass state. A current source control circuit with economizer is operatively connected to the gate of the pass element. A delay circuit is operatively connected to the current source control circuit with economizer and to a command line to command a lower current for holding the contactor closed after a delay has expired for the contactor to transition.
