  2. Cutoff voltage - Wikipedia

    en.wikipedia.org/wiki/Cutoff_voltage

    The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is normally used, whereas 0.9 V is normally used as the cut-off voltage of an alkaline cell ...

  3. Panel switch - Wikipedia

    en.wikipedia.org/wiki/Panel_switch

    A busy line condition was indicated by -48 volt battery applied to the other side of the cut-off relay winding, and thus at the sleeve lead. This would be detected by the final selector as it hunted over the terminals. Starting in 1929, all newer panel systems were deployed as battery cut-off (BCO) systems. [14]

  4. Cut-off (electronics) - Wikipedia

    en.wikipedia.org/wiki/Cut-off_(electronics)

    In electronics, cut-off is a state of negligible conduction that is a property of several types of electronic components when a control parameter (that usually is a well-defined voltage or electric current, but could also be an incident light intensity or a magnetic field), is lowered or increased past a value (the conduction threshold).

  5. Battery eliminator circuit - Wikipedia

    en.wikipedia.org/wiki/Battery_eliminator_circuit

    In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models , which need separate voltages to power the motor and the RC equipment.
