Over & Under 3-Phase Monitor
The Model 269R Over & Under 3-Phase Monitor provides essential protection for industrial systems. It continuously monitors for critical conditions including high voltage, low voltage, phase loss, and phase reversal, safeguarding equipment from operational disruptions. With a robust design, it offers a repeat accuracy of ± 0.1% of set point and a mechanical relay life of 10 million operations, ensuring consistent performance over time. The adjustable reset time, ranging from 0.3 to 5 minutes, allows for application-specific configuration, enhancing operational flexibility. Operating within a temperature range of -20° to +130° F and tolerating 0-97% humidity without condensation, it is suitable for diverse industrial settings. Its 5-year unconditional warranty underscores its reliability in demanding environments, providing long-term assurance. This monitor is a practical solution for maintaining system integrity and minimizing downtime in critical three-phase applications.
