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