Systems and methods for providing consistent and reliable movement of refrigerant within a cooling system for a data center are disclosed. By implementing fluid transfer valves such that a thermosyphon heat exchanger fill loop allows refrigerant to circulate between an isolated refrigerant storage space and a heat exchanger, the data center is cooled more efficiently.

A power distribution apparatus is disclosed. In one example, the power distribution apparatus includes a first power source (102A) configured to provide electrical power to a load (101) and a second power source (102B) configured to provide electrical power to the load (101). A transfer switch (105) is configured to switch a source of power to the load (101) between the first power source (102A) and the second power source (102B). A control circuit (115) is configured to cause the transfer switch (105) to cause a transfer of power to the load (101) from the first power source (102A) to the second power source (102B) in response to a user command and to delay the transfer of power to be within a transfer time window and based on a phase relationship between power provided by the first power (102A) and second power sources (102B).

A power distribution unit may include an input power connector configured to receive input electrical power from an external power source. The power distribution unit may include a primary busbar configured to receive the input electrical power from the input power connector and distribute the input electrical power via a power configuration. The power distribution unit may include an output controller assembly configured to receive distributed input electrical power from the primary busbar and manage the distributed input electrical power. A power distribution unit may include a plurality of receptacles configured to receive the distributed input electrical power from the output controller assembly, wherein power to one or more of the plurality of receptacles is based on the power configuration.

A power distribution unit includes: a backplane with backplane slots; a primary busbar having a least one primary faster hole on one end for fastening the primary busbar to the backplane; and a primary mounting plain extending perpendicularly from an opposing end with at least one primary slot therethrough. The power distribution unit further includes a central busbar having a central mounting plain extending perpendicularly from one end, mounted to the primary mounting plain, and a central slot therethrough on an opposing end. The power distribution unit also includes an ancillary busbar mounted to the central busbar around the central slot.

A signal monitoring system may include two or more amplifiers to simultaneously amplify an input analog signal and generate two or more amplified analog signals, where each of the two or more amplifiers is configured to amplify the input analog signal with a different fixed gain value. The system may further include two or more analog to digital converters to simultaneously digitize the two or more amplified analog signals with a common sampling rate and generate two or more digitized signals. The system may further include a controller to generate a full resolution signal from the two or more digitized signals by selecting on a sample-by-sample basis each value of the full resolution signal from a particular one of the two or more digitized signals associated with an undistorted representation of the input analog signal.

An uninterruptible power supply (UPS) and a power supply system. The UPS includes a first switching module, a rectifier, a second switching module, a direct-current (DC) bus and a controller. A first end of the first switching module is connected to an alternating-current (AC) power supply, and a second end of the first switching module is connected to an input end of the rectifier. Two terminals at a first end of the second switching module are respectively connected to a positive electrode and a negative electrode of a battery pack, two terminals at a second end of the second switching module are respectively connected to the negative electrode and the positive electrode of the battery pack, and a third end of the second switching module is connected to the input end of the rectifier. An output end of the rectifier is connected to a DC bus.

Star-delta convertible connector (200) and method of operating the same for selectively establishing a star configuration or a delta configuration in a three-phase power distribution system are disclosed. The connector includes a socket assembly (202) having multiple receptacles electrically coupled to corresponding terminals and arranged to receive phase conductors and, selectively, neutral conductors, as well as an interchange plug receptacle. The interchange plug (204) includes prongs carrying at least one conductive busbar (222) configured to establish different electrical interconnections based on plug orientation. In a first orientation, the busbar electrically interconnects phase conductors with neutral conductors to establish a star configuration, and in a second orientation, the busbar electrically interconnects phase conductors with one another to establish a delta configuration. Switching between configurations is accomplished by removing the interchange plug, reorienting the interchange plug by approximately 180 degrees, and reinserting the interchange plug, without rewiring, disassembly, or removal of the socket assembly.

A system and method for continuous real-time monitoring of charge levels, e.g., fluid refrigerant available within a refrigerant reservoir of a pumping apparatus for a two-phase cooling system, receives power data corresponding to a current load drawn by each server or information technology (IT) device served by the pumping apparatus. Based on the received power data, the controller infers the expected charge level, e.g., the proportion of fluid refrigerant that should be remaining within the refrigerant reservoir as opposed to circulating in the secondary fluid network of the cooling system, and compares the expected charge level to an actual current charge level sensed within the refrigerant reservoir, initiating a gentle system shutdown and/or generating an alert if the actual charge level sufficiently deviates from the expected charge level based on the received power data.

A system and method for smart pre-cooling in a single-phase or two-phase cooling system maintains a thermal buffer tank in fluid communication with the primary and secondary fluid networks of the cooling system (as applicable) wherein a fluid thermal buffer may be stored to provide reserve cooling capacity. A controller of the cooling system receives weather data, e.g., ambient temperatures for one or more segments of an hour, day, week, or other predetermined duration. For each segment, based on forecasted ambient temperatures, the controller may direct the thermal buffer tank to charge or use reserve cooling capacity to minimize overall energy consumption. For example, when temperatures are lower the thermal buffer tank may charge additional cooling capacity, and when temperatures are higher the thermal buffer tank may deploy reserve cooling capacity to reduce the burden on other chiller devices in removing heat from the system.

A modular data center infrastructure system can include one or more through modules and one or more end modules. The modules can be disposed above one or more cabinets, such as computer equipment cabinets. The modules can be disposed above an aisle between two rows of cabinets and/or coupled to opposing pairs of cabinets. The modules can be coupled to one another. The system can include a first through module coupled above a first opposing pair of the cabinets, a second through module coupled to the first through module and/or above a second opposing pair of the cabinets, and an end module coupled to one of the through modules and/or above a third opposing pair of the cabinets.
