2500D-240
The 2500D 3-Phase Monitor provides essential protection for industrial systems. This device continuously monitors for critical conditions including phase loss, phase reversal, low voltage, and voltage unbalance. Its automatic reset feature simplifies operation, ensuring minimal downtime following a transient event. The monitor's robust DPDT output contacts are rated for 10 amps at 28VDC/300VAC, accommodating diverse control circuit requirements. With configurable nominal AC voltages spanning 120V to 600V, the 2500D integrates into various electrical infrastructures. A trip delay adjustment range of 1 to 10 seconds allows for precise response tuning. Power consumption is 4.5W per phase. Designed for surface mounting, its ABS plastic enclosure ensures durability across an operating temperature range of -4° to +131° F. The unit's ability to not trip on complete power loss enhances system stability. UL listing confirms adherence to safety standards.
The Model 2500D 3-Phase Monitors are designed to continuously monitor
the voltages of a 3-phase power distribution system for abnormal
conditions. The monitors feature solid-state voltage and phase angle
sensing circuits which drive a DPDT electromechanical output relay.
Connect to any 3-phase WYE or DELTA with no neutral connection required.
When the correct voltage and phase sequence is applied to a specified
Model 2500D, the output relay will not energize. An under voltage, phase
reversal, phase unbalance or phase loss condition will cause the output
relay to energize, even if regenerated voltage is present. Complete
power loss will not cause Model 2500D to trip.
