ABSTRACT:
Voltage monitor for monitoring the output voltage of a power source which can be connected to a power load, which includes a reference voltage source, comparators for comparing the power source voltage with the reference voltage, switches between the power source and the load, which can be controlled by an output from the comparators, such that the switches can be closed only when the power source voltages are within certain voltage limits and meet certain conditions, and also such that the load is disconnected when the power source voltages go beyond certain voltage or frequency limits. A timing circuit may also be provided for timing various voltage conditions.
