Abstract: The technology is generally directed to a coordinated power throttling mechanism for a payload using power provided by a rack such that the rack power does not exceed a threshold amount for greater than a predetermined period of time. The coordinated power throttling mechanism includes the rack providing a power throttling signal to the payload and the payload executing the power throttling upon detection of the throttling signal. The payload may detect the throttling signal and, after a delay, execute the power throttling. The delay may ensure that all payloads within the rack have detected the power throttling signal.

Abstract: Methods, systems, and apparatus, for powering AC and DC loads in the event of a power failure. In one aspect, a system includes one or more DC loads that are powered by DC power, one or more AC loads that are powered by AC power, and an uninterruptible power supply (UPS). The UPS includes AC terminals connected to an AC power source and to the one or more AC loads to power the AC loads, DC terminals connected to a backup battery and to the one or more DC loads to power the DC loads a bidirectional AC/DC converter connected between the AC terminals and the DC terminals, and a controller that selectively switches the bidirectional AC/DC converter to the first mode when the AC power source is available and to the second mode when the AC power source is not available.
