Abstract
A power supply particularly for use with a traffic control system has a voltage monitoring and control system which continually monitors the line voltage fed to the traffic control system and automatically turns off the power when the voltage drops below a predetermined minimum for a predetermined time period or provides a warning signal should the voltage drop below a higher second predetermined minimum for a predetermined time interval. In the event that the voltage returns to a predetermined acceptable value for a predetermined time period, the power is automatically restored and the warning signal discontinued. The monitoring system includes sensors operative in response to each of the control parameters which operate in conjunction with logical control circuitry to effect the desired controls.
