ABSTRACT:
A line voltage monitor and controller disconnects AC-powered user equipment from an AC power line whenever the AC power line voltage is outside a predetermined operating voltage window. The equipment is automatically reconnected to the power line only after the power line voltage remains continuously within the operating voltage window for a predetermined delay period. The controller protects the user equipment from both over-voltage and under-voltage (brownout) conditions.
