摘要： A modular overload relay provides a low cost analog base unit performing overload detection functions and one or more add-on units communicating with the base unit through an electric conductor on a side of the base unit to which the add-on module may be attached. The add-on units augment the circuitry of the base unit through additional analog or microprocessor-based circuitry communicating with various points within the analog circuitry of the base unit.

摘要： A circuit is provided for rectifying and amplifying an AC input waveform to optimize the dynamic range of downstream circuitry, such as an analog-to-digital converter. The circuitry includes an inverting amplifier and a non-inverting amplifier. The inverting amplifier includes a selectable resistance network in a feedback loop that permits the gain to be adjusted by appropriate selection of conductive states of solid state switches. The non-inverting amplifier includes a selectable resistance network on an input line. A control circuit, such as a microprocessor, monitors the output of the A/D converter and controls the conductive state of switches in the feedback and input networks to maintain the digital output within a desired portion of the dynamic range of the A/D converter. Several discrete gains may be provided and programmed in accordance with a predetermined selection scheme.

摘要： A circuit for and method of controlling transient currents on power conductors includes a voltage-controlled switch connected between one of the power conductors and a load. A turn-on circuit is connected to the switch to control the switch during a transition period in which the switch changes from a non-current conducting state to a conducting state in which a static current flow to the load can be maintained. The turn-on circuit controls turn-on such that the rate of rise and the peak amplitude of the current through the switch is limited during the transition period. A reset circuit also is connected to the voltage-controlled switch to reset the switch to a non-conductive state when the voltage between the power conductors drops out. The reset circuit is configured to reset the switch within a reset period having a duration that is shorter than the duration of the transition period. The circuit and method are particularly suited for use in a network in which the power conductors provide electrical power to a plurality of nodes, and are even more suited for use in a network in which the power conductors and the data conductors, which transmit data between nodes, are disposed within a single media cable.

摘要： A system and method for measuring current flow through a conductor. The system includes a core having a general ring shape and a central opening. The core terminates at two ends that form a gap for receiving a Hall generator. The core is electrically coupled to a ground to prevent electrical noise on the conductor from being coupled to the Hall generator, thus permitting the direct use of the voltage signal output by the Hall generator.
