Power Supply Efficiency Boost Increase your power supply efficiency by using a QBAR switch to lower the parasitic current drain through the bleeder resistor during normal supply operation. A QBAR switch, OFF during normal operation, is turned ON at supply turn-off and stays ON when all voltages fall to zero. Indicate Status Simply and Reliably HI on the status line drives GO indicator through a ...

Alarm System - QBAR Switch...

Alarm System - QBAR Switch in Series with Load A QBAR switch will reliably activate an alarm (a warning display, a cooling fan, a not-ready indicator, or any other load that should be driven during failure) over a wider range of fault conditions than other switch types.The QBAR switch will turn the alarm on when: LO on the status output indicates system failure +5 V supply is lost status conduc...
