Model 2644 3-Phase Monitor
The Model 2644 3-Phase Monitor provides essential protection for industrial systems. Its capability to detect phase loss, low voltage, and phase reversal safeguards critical equipment from electrical anomalies. With a nominal AC voltage of 120VAC (phase to phase) and an adjustment range of 85-120V, it offers adaptability for various application requirements. The unit features a restart delay of approximately 3.5 minutes, ensuring controlled system re-engagement. A response time adjustable from 0.2 to 20 seconds allows for precise control over fault reactions. DPDT 10 amp output contacts ensure reliable switching for connected loads. This monitor is designed for consistent performance in environments ranging from -20° to +131° F, supported by a 5-year unconditional warranty. Its robust design, precise monitoring capabilities, and transient protection of 2500 VRMS contribute to operational continuity and equipment longevity.
