Abstract: There is disclosed an enclosure and cooling system for electronic equipment that provides forced-air cooling of multiple compartmentalized electronics assemblies while simultaneously isolating the electronics assemblies from the ambient environment, keeping the electronics assemblies free from contamination due to harmful dust, dirt, water, corrosives, and other airborne foreign matter. Embodiments include an air-conduction cooled environmentally-sealed electronics enclosure having at least first and second environmentally-sealed electronics compartments, each containing a respective electronic assembly. A common-air cooling channel containing a fin core is disposed between the first and the second electronics compartments, such that ambient air drawn from an air intake, through the common channel, and out an air exhaust removes heat generated by the electronic assemblies within the sealed compartments to an exterior of the enclosure. Other embodiments are disclosed.

Abstract: The disclosure provides embodiments of a self-contained automatic battery charging system having a power printed circuit board (PCB) that enables inputting an alternating current (AC) power flow to the automatic battery charging system. A first switchmode converter converts an AC input power to a direct current (DC) power, thereby providing an active power factor correction. The first switchmode converter comprises an isolation transformer, which provides an electrical isolation between a primary circuitry and a secondary circuitry of the automatic battery charging system. A second switch mode converter regulates a system output voltage and limits a system output current to an electrical load. A DC output is connected to a battery, another electrical storage device, and/or a parallel-connected DC load to be powered.

Abstract: There is disclosed a dynamic boost charging system having a monitoring component configured to measure total DC current and/or battery current and a reporting component configured to transmit output data of the total DC current and/or battery current measured. A battery charger control system in operable connection with the monitoring component receives the data of the total DC current and/or battery current measured by the monitoring component, and is configured to: obtain an initial time and/or charge measurement; determine a time and/or charge to complete a recharge cycle based on the time and/or charge measurement; selectively use at least two preset DC output voltage settings, one of the at least two preset DC voltage settings being a float voltage, and another of the at least two preset DC voltage settings being a boost voltage; and maintain the boost voltage until the time has passed the charge has been provided.

Abstract: Disclosed herein is an embodiment of a charger having a power printed circuit board (PCB) that enables an alternating current (AC) power to flow into a self-contained automatic battery charging system. A first switchmode converter converts an AC input power into a direct current (DC) power thereby to provide an active power factor correction to obtain an improved power factor. The first switchmode converter comprising a high frequency isolation transformer which provides an electrical isolation between a primary circuitry and a secondary circuitry of the self-contained automatic battery charging system. A second switchmode converter connected to a DC output from the first switchmode converter regulates system output voltage and limits system output current to an electrical load. The DC output is connected to a battery and/or another electrical storage device to be charged and/or to a parallel-connected DC load to be powered.
