    摘要： A method to detect component removal while operating in a battery backup mode, comprising providing power from a battery backup unit (BBU) to a control card memory device, and measuring the current drawn by the control card memory device. If the current drawn by the control card memory device is less than or equals a pre-determined disconnect current, the method determines if a BBU release pin has been asserted. If the BBU release pin has been asserted, the method encodes in an event log a battery backup removal event. If the BBU release pin has not been asserted, the method encodes in the event log a control card removal event.

    摘要： A circuit for dynamically increasing the drop-out voltage of an electromechanical automatic transfer switch (ATS) into a brownout voltage range is provided. The automatic transfer switch includes a first input, a first coil connected to the first input, and a first, normally-open auxiliary contact in magnetic communication with the first coil. The circuit includes a first resistor adapted to connect to the first, normally-open auxiliary contact, and a first transformer having a primary winding connected to the first resistor, and a secondary winding adapted to connect to the first coil. An operating voltage across the first coil is reduced a proportional amount by a secondary voltage across the secondary winding when the first, normally-open auxiliary contact is closed.
