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.
