An internal cooling grid is mounted internal to a facility, such as a data center, and includes a plurality of fluid transport elements arranged in a grid pattern with nodes at intersections of the grid pattern. Supply and return manifolds included in the nodes receive (and return) cooling fluid from/to more than two transport elements. Thus, a failure of one or more transport elements does not prevent a node from being supplied cooling fluid from at least a first transport element and a second transport element. In some embodiments, the cooling grid may be operated at a pressure less than one atmosphere, such that any leaks that occur cause air to leak into the cooling grid instead of cooling fluid leaking out of the cooling grid.

A power distribution grid for a facility, such as a data center, is located within the facility. The power distribution grid includes a plurality of power transport elements arranged in a grid pattern and nodes located at intersections of the grid pattern. Electrical loads are supplied power via respective nodes of the power distribution grid. Also, each node is supplied power from more than two transport elements, such that one or more transport elements can fail and electrical loads connected to a particular node associated with the failed transport elements continue to receive electrical power supplied to the particular node from at least two different transport elements.

The device includes an electric energy source to which an inverter is power-connected, whose output is three-phase with symmetrical power distribution. It further includes an inter-phase power transfer module which is power-connected to the inverter and comprises at least one first power board including at least three power transistors. The inter-phase power transfer module has a data interface and has a first output with asymmetrical power distribution into three phases, wherein the first output is further connected to a distinctive nodal point, this distinctive nodal point being power-connected to a load. Through a measuring module, the PLC control system is also connected to the distinctive nodal point, the PLC control system being further connected also to the inverter and the data interface. This arrangement ensures that the power supplied to the load reflects in each phase the power consumed by the load. The device further offers additional possibilities to control energy production, consumption and storage.

A power supply circuit in a PLC includes a first node that receives a DC voltage with a first level, a second node that outputs a voltage for driving a control unit, wiring connecting the first and second nodes, a first rectifier on the wiring having a forward direction from the first node to the second node, a charger for charging and discharging, a first converter that converts a discharging voltage from the charger into a DC voltage with a second level lower than the first level and outputs the voltage, and a second rectifier connected between an output of the first converter and the second node to have a forward direction from the first converter to the second node.

The invention relates to a programmable logic controller having an energy supply that provides electric energy to operate the unit and having at least one measurement input, with the measurement input being configured to measure and/or detect an electrical input signal. The programmable logic controller is characterized in that at least some of the electric energy of the input signal is supplied to the energy supply.

Systems, methods, and devices are disclosed herein for the integrated design and deployment of process control logic and power control logic in the context of industrial automation environments. In an implementation a computer displays, in an integrated design environment, representations of process control logic for controlling manufacturing devices an industrial automation process and of power control logic for controlling electrical devices in the industrial automation process. The computer further deploys the process control logic and the power control logic to a programmable logic controller (PLC) that controls the industrial automation process.

The convenience of a design of a system is improved by making it easier to verify consumed electric power when designing and constructing the system. An operation screen is displayed upon execution of on a PC for supporting the design of a control system. The configuration of a control system can be controlled in an editing region, and unit images representing an I/O unit are connected in order to a unit image representing a communication coupler. A power supply unit can be inserted into this configuration. An icon indicates a shortage of electric power to the units downstream of the unit indicated by a selected image. When a user mouses the pointer over the icon, the detailed meaning of the icon is displayed in a message. The designer is thus capable of easily verifying the position at which a power source supply unit should be added.

Methods and apparatus relating to techniques for dynamic control of liquid cooling pumps to provide thermal cooling uniformity are described. In an embodiment, modification is made to operation of one or more of: one or more cooling pumps or one or more fans, based at least in part on comparison of one or more detected temperature or noise values at one or more components of a processor with one or more corresponding threshold values. The processor may include the logic that causes the modification and one or more sensors. The sensors are thermally or acoustically coupled to the one or more components of the processor to determine the detected temperature or noise values. Other embodiments are also disclosed and claimed.
