Model 2644 3-Phase Monitor
The Model 2644 3-Phase Monitor provides essential protection for industrial equipment. This device accurately detects critical power anomalies including phase loss, low voltage, and phase reversal, safeguarding machinery from potential damage. Its adjustable response time, ranging from 0.2 to 20 seconds, allows for precise system integration. A built-in restart delay of approximately 3.5 minutes ensures controlled system re-engagement after power fluctuations, preventing immediate restarts that could stress components. Operating reliably across a temperature range of -20° to +131° F, this monitor maintains consistent performance in diverse industrial environments. With a nominal AC voltage of 208/240VAC and an adjustment range of 160-240V, it offers broad compatibility. The unit's low power consumption of 1.5W contributes to energy efficiency. This monitor offers dependable operational continuity and reduced downtime for critical three-phase applications.
