Abstract: Systems, devices, and related methods for automated testing of an automatic transfer switch. A device for testing an automatic transfer switch includes a primary power supply input, a controlled primary power output, a primary power source selection assembly, an output electrical power monitor unit, and a control input. The power source selection assembly is controllable to enable selective communication of electrical power received via the primary power supply input to the controlled primary power output. The output electrical power monitor unit is configured to monitor electrical power supplied to a connected load via the automatic transfer switch. The control input is operatively coupled with the primary power source selection assembly and the output electrical power monitor unit to enable control of the operation of the primary power source selection assembly via an external controller and to transfer output from the output electrical power monitor unit to the external controller.

Abstract: Techniques are described for providing an automatic transfer switch (ATS), such as in a data center, to switch between a primary power system and a reserve power system based on a priority of the computing systems to which the ATS is supplying power. The ATS obtains the priority from a centralized database and obtains an existing load on the reserve power system. If the existing load is too high and the priority of the computing systems coupled to the ATS is too low, then the ATS may not switch to utilizing the reserve power system upon a failure in the primary power system.

Abstract: Automatic transfer switching apparatus and systems include a switching device including an input line, a sensor, and a parallel assembly of a solid-state relay and latching relay electrically connected with the input line. The solid-state relay is used to short the latching relay such that the latching relay can be opened and/or closed in an unloaded state while the input line is energized.

Abstract: An automatic transfer switch (ATS) includes power quality conditioners to condition electrical power fed to a power output of the automatic transfer switch. In some embodiments, the power quality conditioners include a surge protection circuit or a filter circuit. In some embodiments, the automatic transfer switch includes a battery module configured to supply electrical power to the power output of the ATS during a power disruption event.
