摘要： Implementations are described for a modular power distribution unit (PDU) for a rack-mountable power tray or power shelf. The modular PDU includes a housing defining an input face and an opposing output face, and a plurality of power cables extending to the input face. The modular PDU further includes one or more second power connectors arranged at the output face, and distribution circuitry configured to distribute power from a first power bus and a second power bus to the one or more second power connectors. The modular PDU further includes one or more fasteners configured to attach the output face of the housing to the face of the power tray or power shelf, wherein the one or more second power connectors are retained in a coupled configuration with the one or more first power connectors.

摘要： According to an embodiment, a surge protector includes a capacitor, a switch, and a first transistor. The capacitor charges based on an input power to the surge protector. The switch turns on when the capacitor is charged to a charge threshold. The surge protector outputs the input power when the switch is turned on. The first transistor turns on when a voltage of the input power exceeds a first input voltage threshold such that the capacitor discharges to below the charge threshold and such that the switch turns off. The surge protector stops outputting the input power when the switch is turned off.
