Model 19 3-Phase Monitor with Trip & Restart Delays
The Model 19 3-Phase Monitor offers essential protection for industrial systems. It accurately detects phase loss, low voltage, and phase reversal, safeguarding connected equipment from operational disruptions. With an automatic reset type, the unit minimizes downtime by restoring power once conditions stabilize. Users can configure precise operational parameters through adjustable trip delays, ranging from 1 to 30 seconds, and restart delays, from 1 to 300 seconds. This flexibility allows for tailored system response to varying load conditions. The monitor is compatible with both Wye and Delta systems, requiring no neutral connection for simplified integration. Its robust design, featuring SPDT 10 amp output contacts and a five-year unconditional warranty, ensures consistent performance and reliability in demanding operational environments. Power consumption is 1.4W.
