Abstract: A human interface module includes a body. At least one input device and at least one output device are connected to the body. A mounting protrusion projects outwardly from the body and that is adapted to be received through a mounting aperture defined in a door or other cabinet panel for fixedly securing said body to the panel. The mounting aperture can be punched and include an alignment notch that receives a locator nib of the mounting protrusion. A nut can be advanced on a threaded portion of the mounting protrusion to secure the body to the panel. The body can be a bezel that receives a removable interface module. A USB Type-C or other electrical connector can be connected to the body and is adapted to mate with a corresponding mating connector of a cable. The connector can be accessible through a hollow core of the mounting protrusion.

Abstract: Motor drive power conversion systems are provided including a rectifier and a switching inverter, wherein the switching devices of the rectifier, the inverter and/or of a DC/DC converter are silicon carbide switches, such as silicon carbide MOSFETs. Driver circuits are provided for providing bipolar gate drive signals to the silicon carbide MOSFETs, including providing negative gate-source voltage for controlling the off state of enhancement mode low side drivers and positive gate-source voltage for controlling the off state of enhancement mode high side drivers.

Abstract: A method and apparatus for predicting junction device temperature of at least a first switching device in a power conversion module that includes the first switching device and at least a second switching device, the method comprising the steps of identifying a cross thermal impedance value indicative of how the temperature of the second switching device effects the first switching device temperature an using the cross thermal impedance value to predict the temperature of the at least a first switching device.

Abstract: An automated sample conditioning system for conditioning and preparing steam and hot water samples at a constant flow rate and velocity continuously monitors and adjusts flow rate in the sample line. Sample flow is metered through a flow rate device such as an orifice plate of known flow characteristics, and a downstream pressure value is provided by either a fixed back pressure regulator/relief valve or by a pipe section of known length and diameter. A pressure transducer continuously monitors pressure in the sample line upstream from the orifice plate. A control analyzer automatically adjusts a motorized pressure reducing device in response to fluctuations in pressure monitored by the pressure transducer in order to maintain constant flow rate and velocity. Monitoring devices and displays acquire, display and control critical pressure, temperature and flow rate parameters throughout the system. Network communications capability for remote, unattended monitoring control and data acquisition is also provided.
