摘要： The present disclosure is a system and method for measuring both load current and residual current within an electronic component. The electronic component includes a first toroidal core for measuring load current and a second toroidal core for measuring residual current, all enclosed within a housing. The system facilitates the measurement of load current and residual current in a small form factor and may be configured to replace legacy electronic components that measure only load current.

摘要： An electrical device with buoyancy-enhanced cooling is provided. The electrical device includes a housing having a first portion including a heat sink and a second portion coupled to the first portion. The heat sink includes a plurality of hollow fins. A cover plate is positioned within the housing and is coupled to the first portion of the housing. The cover plate defines openings between an interior of the housing and the plurality of hollow fins and the openings are located at each end of each hollow fin. Further, an electrical component is positioned within the interior of the housing. Air heated by the electrical component is permitted to circulate within the housing and is directed through the hollow fins based on buoyancy forces (e.g., such that the air is permitted to cool within the hollow fins based on conduction, convection, and/or radiation).

摘要： The present disclosure relates to a system for controlling a supply air temperature adjustment for a cooling unit to optimize operation of the cooling unit with respect to at least one of room air temperature and humidity requirements. The system uses a controller for implementing: a machine learning module configured to select which portion or portions of acquired data pertaining to operation of the cooling unit will be utilized; and a neural network model which uses information supplied by the machine learning module and learns an operational behavior of the cooling unit, and wherein the machine learning module performs supervised learning and regression for the neural network model, and wherein the neural network model uses information supplied by the machine learning module for generating an output. The controller also implements an optimization module which receives the output from the neural network model and which implements a global optimization routine, using unit power consumption of the cooling unit as the objective function, to produce a supply air temperature set point for use by the cooling unit which optimizes an operating parameter of the cooling unit.

摘要： The present disclosure relates to a shared transfer switching system with built in relay testing ability, for transferring power received by a load from a preferred AC power source to an alternate AC power source, or transferring power being received by the load from the alternate AC power source to the preferred AC power source. The system selectively controls various ones of the relays used to apply power from either the preferred or alternate power sources to the load, such that the relays are switched from open to closed states at controlled times, while voltage measurements are made at select locations between the relays. The system can identify which specific ones of a plurality of relays associated with each of the preferred and alternate power sources has properly opened and closed, and thus verify that all of the relays needed to switch between the preferred and alternate power sources are operating properly.

摘要： A power control system may Include an uninterruptible power supply (UPS), a display-device, load measurement circuitry to determine a load percentage of the UPS, and a controller. The controller may receive the load percentage of the UPS from the load measurement circuitry; monitor the load percentage of the UPS to determine whether the UPS is operating in a nominal load state or an overload state; generate an input overload countdown timer when the UPS is operating in the overload state, where the input overload countdown timer provides an estimated time remaining in the overload state; generate an output overload countdown timer by applying a minimum envelope filter to the input overload countdown timer; and direct the display device to display the output overload countdown timer. Additionally, the minimum envelope filter may be operated in an open-loop or a closed-loop configuration.

摘要： A device may include an rectifier with one or more transistors that accepts a three phase AC input and generates a DC bus output, a low-pass filter to provide a filtered DC bus voltage, a driver to drive the transistors based on a modulation index, and a controller to generate the modulation index. The controller may generate a nominal modulation index, generate an adjusted modulation index based on the nominal modulation index modified by a ratio of the filtered and measured DC bus voltages, and provide the modulation index to the PWM driver, where the modulation index is the nominal modulation index when a difference voltage associated with a difference between the filtered and measured DC bus voltages is below a voltage threshold, and where the modulation index is the adjusted modulation index when the difference voltage is above the voltage threshold.

摘要： In one aspect the present disclosure relates to a battery cabinet apparatus having flame and noxious gas management capability. The apparatus has a plurality of parallel arranged vertical frame elements, a plurality of spaced apart shelves disposed within an interior area of the apparatus, and a plurality of louver panels. The louver panels are arranged one above another and coupled to a first pair of the vertical frame elements. Each of the louver panels has an upper portion and a lower portion, where the lower portion, angles inwardly, relative to the interior area of the apparatus. In this manner the upper portion of a first one of the louver panels cooperates with the lower portion of a second one of said louver panels disposed immediately above the first one of the louver panels to form an opening for exhausting at least one of flames or noxious gasses that develop within the apparatus.

摘要： The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to help control powering a load when an AC mains power source is not available to provide power to the load. The system has a power converter forming an uninterruptible power supply, and includes a controller configured to control operation of the power converter. A supplemental battery subsystem is included which is in communication with the power converter for supplying DC power to the power converter. The controller monitors the application of power from the utility proxy to the load and uses the DC power supplied by the supplemental battery subsystem, when needed, to supplement the generation of power by the power converter, to thus assist the power converter in powering the load along with the power being provided by the utility proxy.

摘要： The present system relates to a power topology mapping system for identifying which one of one or more equipment components are being powered from a specific phase of a multi-phase AC power source. The system makes use of a plurality of power receiving subsystems which each receive an AC power signal from at least one phase of the multi-phase AC power source. Each power receiving subsystem has a communications card, an identification designation unique to it, and a controller. One of the power receiving subsystems is designated as a reference power domain component. The controllers each carry out phase angle measurements associated with the AC power signal being received by its power receiving subsystem. A topology mapping subsystem is included which analyzes phase angle measurement data reported by the power receiving subsystems and determines which subsystem is being powered by which phase of the multi-phase AC signal.

摘要： The present disclosure relates to a system for controlling power walk-in for an uninterruptible power supply (UPS) being switched to receive AC power from an AC generator. The system may have a control system and a power walk-in (PWI) subsystem. The PWI subsystem may be controlled in part by the control system. The PWI subsystem may be configured to control at least one of an input current or an input power of an AC signal being provided by an AC generator during a power walk-in operation to attempt to maintain a minimum frequency of the AC signal from the AC generator during the power walk-in operation.
