B2638-208/240V
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.
The Model 2638 3-Phase Monitor combines a 3-phase monitor with a line
voltage and phase sequence indicator. Like other Time Mark Monitors, the
Model 2638 senses phase loss, phase reversal and low voltage. When
power and phasing are correct, the internal relay energizes. LED
indicators will show that all phases are present, and the direction of
phase rotation. When a fault occurs, the monitor trips its relay and
indicates which phase is lost, or, if a reversal is present. This allows
you to automatically protect your equipment by correcting the
appropriate fault condition. The Model 2638 will automatically reset
when correct power is restored. It is available in 208/240 VAC, 480 VAC,
or 380 VAC/50 Hz.
