The Model 268 Over & Under Voltage Monitor is designed to ensure that the monitored operating voltage remains within a 120 VAC band. This device uses a dual op-amp comparator circuit to achieve stable and repeatable trip set-points. The output relay is energized only when the voltage being monitored remains between the upper and lower set-points. Voltages above or below the set-points will de-energize the relay, and illuminate the appropriate indicator LED. The Model 268 Over & Under Voltage Monitor is designed for continuous duty operation.
