  • Low voltage warning apparatus and method
    Patent number: 5034728
    Abstract: A low voltage warning apparatus is adapted to energize a low voltage indicator in response to a test voltage signal falling below the magnitude of a reference voltage signal. The test voltage signal and reference voltage signal are connected to be received by a comparator circuit so that the comparator circuit output is connected to ground when the test voltage falls below the value of the reference voltage. The low voltage indicator is connected between an indicator power supply and the comparator output so that when the comparator output is connected to ground, a low voltage indicator energizing current flows through the low voltage indicator to provide the desired low voltage indication.
