    Typical usages include: Electrical ballast circuits to switch them off in the event of voltage falling below the operational value. [2]Switched-mode power supplies.When the system supply output impedance is higher than the input impedance of the regulator, an UVLO with a higher hysteresis should be used to prevent oscillations before settling down to a steady state and possible malfunctions of ...

    en.wikipedia.org/wiki/Emergency_light

    An emergency light is a battery-backed lighting device that switches on automatically when a building experiences a power outage. In the United States, emergency lights are standard in new commercial and high occupancy residential buildings, such as college dormitories , apartments , and hotels .

  4. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

    Reduced voltages can bring control signals below the threshold at which logic circuits can reliably detect which state is being represented. As the voltage returns to normal levels the logic can latch at an incorrect state; to the extent that even " can't happen " states become possible.

  6. Residual-current device - Wikipedia

    en.wikipedia.org/wiki/Residual-current_device

    A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.

    To prevent electric power distribution network damage, each station along the network is protected with circuit breakers or fuse cutouts which turn off power in the event of a short circuit. These protection solutions present a major problem when restoring power immediately following transient events, because repair crews need to manually reset ...

  9. Transient-voltage-suppression diode - Wikipedia

    en.wikipedia.org/wiki/Transient-voltage...

    A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond, but in a practical circuit the inductance of the wires leading to the device imposes a higher limit. This makes transient ...
