Abstract: An example system includes a rectifying component to convert an alternating current (AC) signal into a direct current (DC) signal. The system also includes a filtering component. The filtering component determines that a plurality of AC cycle drops have occurred and will deactivate the AC signal in response to that determination. Furthermore, the system includes an isolating component. The isolating component consumes greater than a threshold level of power in one state and less than a threshold level of power in another state. The isolating component is operating in the state that consumes greater than a threshold level of power when the signal that indicates the AC voltage is at a level in which it may allow the device to operate safely and properly is deactivated.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a plurality of power outputs, a logic controller and a single switch. Each one of the plurality of power outputs is communicatively coupled to a respective current/power sensor. The logic controller is communicatively coupled to the respective current/power sensor of each one of the plurality of power outputs. The single switch is communicatively coupled to the logic controller and the respective current/power sensor of each one of the plurality of power outputs. Power to each one of the plurality of power outputs is controlled by the logic controller via the single switch.
