Abstract:
A shroud that includes a body, a cavity, a curved outlet, and at least one non-linear channel. The body can have a top end and a bottom surface, as well as a first end and a second end located opposite the first end. The cavity can be located under the top end of the body and disposed toward the first end. The curved outlet can be disposed toward the second end of the body and have a banana-shaped vent that traverses at least two sides of the body. Each linear channel can include a bent passage, a third end, and a fourth end, where the third end adjoins the cavity, and where the fourth end adjoins a portion of the banana-shaped vent of the curved outlet. The curved outlet and the at least one non-linear channel can prevent substantially all liquids and solids outside the body from entering the cavity.
Abstract:
A system for transferring heat from an electrical enclosure is provided. An electrical enclosure defines a housing area in which one or more electrical devices are housed. A heat pump extends through the electrical enclosure, the heat pump defining a channel configured to communicate fluid for transferring heat from the one or more electrical devices. The electrical enclosure is substantially sealed from the heat pump channel and from other areas outside the electrical enclosure.
Abstract:
A system for suppressing an overheat condition in an electrical housing includes an electrical housing that defines a housing area including one or more electrical devices; a suppression fluid container containing a suppression fluid; a valve configured to regulate the flow of the suppression fluid from the suppression fluid container to the housing area; at least one sensor configured to sense at least one of temperature and smoke; and a controller communicatively connected to the at least one sensor and the valve, the controller configured to receive signals from the at least one sensor indicating an overheat condition in the housing area; and in response to the received signals indicating the overheat condition in the housing area, control the valve to allow the suppression fluid to flow from the suppression fluid container into the housing area, in order to suppress the overheat condition in the housing area.
Abstract:
A power converter includes a transient voltage protection circuit connected between an input of the power converter and a power stage of the power converter. The transient voltage protection circuit provides a low resistance connection from the input of the power converter to the power stage of the power converter when the input voltage is less than a predetermined threshold, but blocks the input voltage from the power stage when the input voltage is equal to or greater than the predetermined threshold voltage. The power converter may be a boost power converter used in a vehicle to provide power from a main power bus of the vehicle to a subsystem of the vehicle such as an anti-lock brake system.
Abstract:
A power converter includes a bypass circuit connected in parallel with a power stage of the power converter. The bypass circuit provides a lower loss current path in parallel with the power stage when an input voltage of the power converter exceeds a predetermined threshold. The power converter may be a boost power converter used in a vehicle to provide power from a main power bus of the vehicle to a subsystem of the vehicle such as an anti-lock brake system.
Abstract:
The invention can provide for a power supply, and in particular a fieldbus power supply, comprising a plurality of power supply modules each arranged to output power on a plurality of channels; a current share controller arranged to share an output current requirement across the plurality of power supply modules and wherein; at least a second of the plurality of channels in each module is arranged to track the loading of the first of the plurality of channels in each respective module and so that a multichannel and multimodule power supply with reduced power handling requirements for each module can be provided.
Abstract:
A device includes a cover that includes a base. The cover is configured to be positioned over a mount that couples a support structure of an electrical device to another element. The electrical device includes an energized terminal that is configured to connect to an electrical power system and a grounded terminal. The device also includes an insulating interface coupled to the base of the cover such that, when the cover is positioned over the mount, the interface contacts the support structure to substantially electrically insulate the mount. A system includes an electrical device, a support structure that holds the electrical device on the first side, a mount configured to couple the structure to another element, the mount being grounded during operation of the system, and a protective device positioned over the mount.
Abstract:
A light emitting diode (LED) floodlight is described herein. The LED floodlight can include a LED housing assembly coupled to a driver assembly. The LED housing can include a number of LEDs mounted on a front side of a LED housing and a number of heat sink protrusions extending from a back side of the LED housing. The driver assembly can include a driver mounted within a driver housing, where the front side of the driver housing couples to the end of the heat sink protrusions that extend from the back side of the LED housing. The LEDs may be coupled to a number of reflectors. The reflectors can include a reflector body having a top portion and a bottom portion. The top portion can form a shape that is an elongated version of the shape formed by the bottom portion.
Abstract:
A manifold within an explosion-proof enclosure is described herein. The manifold can include an inlet duct coupled to an air moving device, where the inlet duct can receive exhaust air from the air moving device. The manifold can further include an outlet duct that includes a perimeter and at least one channel, where the outlet duct can send the exhaust air outside the explosion-proof enclosure, where the perimeter of the outlet duct is coupled to a first portion of an inner surface of an outer wall of the explosion-proof enclosure, and where the first portion of the inner surface includes at least one aperture that traverses the outer wall. The manifold can also include a body that includes a cavity, where the body couples the inlet duct to the at least one channel, and where the exhaust air flows from the inlet duct through the cavity to the outlet duct.
