3-Phase Monitor with Line Voltage & Phase Sequence Indicator
The Model 2638 3-Phase Monitor provides essential protection for industrial systems. It detects critical conditions including phase loss, phase reversal, and low voltage, ensuring operational integrity. With a rapid 0.05-second response time, it minimizes potential equipment damage. Integrated LED status indicators offer immediate diagnostic feedback, simplifying troubleshooting. The automatic reset function streamlines system recovery after a fault event, reducing manual intervention. This device operates reliably across a -20° to +131° F temperature range and tolerates 0-97% humidity without condensation. Its SPDT 10A output contacts at 240VAC resistive provide robust control for various applications. A 5-year unconditional warranty underscores its durability and consistent performance in demanding environments. This monitor is a practical solution for maintaining system uptime and protecting valuable assets.
