Over & Under 3-Phase Monitor
The EX269R Over & Under 3-Phase Monitor offers essential protection for industrial electrical systems. This device monitors critical conditions including high voltage, low voltage, phase loss, and phase reversal, ensuring operational integrity. With a nominal AC voltage of 380VAC and adjustable upper/lower ranges (350-450V and 300-400V respectively), it adapts to specific system requirements. Its 50Hz frequency compatibility and 6W power consumption demonstrate efficient integration. The monitor features a fixed response time of 4 ±2 seconds and an adjustable reset time from 0.3 to 5 minutes, allowing for tailored system recovery. Output contacts are SPDT 10A at 240VAC resistive, providing reliable control for connected equipment. Designed for consistent performance, it operates within a -20° to +130° F temperature range and tolerates 0-97% humidity without condensation. Its 10 million mechanical operations relay life ensures long-term durability.
