Abstract
A method of regulating the operation of an electrical system. The electrical system includes, a load, at least one sensor coupled to the load configured to measure at least one characteristic of the load, a solenoid having at least one coil, at least one sensor coupled to the solenoid coil configured to measure at least one characteristic of the coil. A control circuit is coupled to the at least one load sensor and the at least one coil sensor, and includes a memory. The method includes receiving, by the control circuit, at least one load characteristic from the at least one load sensor, determining, by the control circuit, a force sufficient to maintain an electrical contact, based on the at least one load characteristic, and regulating, by the control circuit, a coil current, based on the force and based on the at least one characteristic of the coil.
