    Abstract: The present disclosure provides embodiments of direct current (DC) power connectors and methods to manufacture the same. More specifically, the present disclosure provides a connector plug with improved power capacity and structural rigidity. The connector plug includes an inner body and an outer body coupled to transmit power through the DC power connector, wherein the inner body is concentrically arranged within the outer body, and an insulating barrel that is coupled between the inner body and the outer body to electrically isolate the inner body from the outer body. The inner body and outer body comprise a base metal or metal alloy having an electrical conductivity ranging between 30% International Annealed Copper Standard (IACS) and greater than or equal to 99% IACS. In addition, the inner body, outer body and insulating barrel comprise an inter-locking feature, which increases the structural rigidity of the connector plug and prevents disassembly when the inner body, outer body and insulated barrel are assembled together.

    Abstract: Systems and methods are provided to implement power supply units (PSUs) that are capable of operating on input power having different types of input voltage waveforms, including, but not limited to, pure sinusoidal waveforms, non-pure sinusoidal waveforms, and non-sinusoidal waveforms. Such a PSU may operate to continue supplying DC output power to a system load as long as the PSU is powered by any one of a variety of such different input power types, while at the same time also effectively monitoring for presence of input power provided to the PSU and shutting down the PSU in event of absence or termination of the input power to the PSU. Such a PSU may also automatically identify and adapt to changes between different types of input power while at the same time continuing to supply DC output power to a system load in an uninterrupted manner for as long as some type of input power is being provided to the PSU.

    Abstract: A disclosed method for LED control for a detachable reversable power cable includes detecting, at a power source, that a first connector at a first end of the power cable is connected to the power source, triggering, at the power source, a first pulse on a first wire of the power cable that turns off a first LED switch coupled to a first LED on the first connector, disabling the first LED, and triggering, at the power source, a second pulse on a second wire of the power cable that drives a second LED on a second connector at a second end of the power cable opposite the first end, the second LED being coupled to a second LED switch that is on. The method further includes, responsive to detecting that the second connector is connected to a power sink, modifying a driver path for the second LED.
