Over/Under Voltage Monitor
The Model 268 Over/Under Voltage Monitor offers essential protection for 120VAC systems. This device continuously monitors voltage, safeguarding equipment from damaging fluctuations. Its adjustable trip points for both high and low voltage ensure precise control, while the automatic reset feature minimizes downtime. With a robust 10A contact rating at 240VAC resistive and a continuous duty cycle, the Model 268 provides reliable operation in demanding industrial environments. The unit maintains setpoint stability of 0.1% max under fixed conditions and tolerates 0-97% humidity without condensation, ensuring consistent performance across a wide operating temperature range of -20° to +130° F. Its rapid 50ms response time allows for quick detection of anomalies, preventing potential equipment damage. This monitor is a critical component for maintaining system integrity and extending equipment lifespan in various industrial applications.
