D265-575VAC
The Model 265 3-Phase Monitor provides essential protection for industrial systems. It continuously monitors for critical conditions including phase loss, low voltage, and phase reversal, ensuring equipment integrity. With an automatic reset function, operational downtime is minimized without requiring manual intervention. This device supports 575VAC nominal systems, offering an adjustment range of 450-575V for precise application. Its robust design includes SPDT 10 amp output contacts and a rapid 50ms maximum response time, facilitating prompt system response. The monitor operates reliably across a wide temperature range, from -20° to +131° F, making it suitable for diverse industrial environments. UL Recognized and CSA Certified, it delivers consistent and dependable performance for critical machinery protection.
The Model 265 3-Phase Monitor continuously monitors 3-phase Wye or Delta
systems for phase loss, low voltage and phase reversal. When properly
adjusted, the Model 265 Monitor will detect phase loss on a loaded motor
even when regenerated voltage is present. The solid-state sensing
circuit drives an internal relay, in a fail-safe configuration, i. e. ,
the relay is energized when correct voltage and phase rotation are
applied. Operating power for the Model 265 is drawn from the 3-phase
lines being monitored. An adjustable timer delays restarting of the
load, allowing up to five minutes for compressor head pressures to bleed
off, in the event of short-term power failures. The Model 265 Monitor
is not sensitive to line current, and can be used with any size motor or
compressor. Automatic and manual reset versions are available.
