3-Phase Monitor with Adjustable Trip & Restart Delays
The 3-Phase Monitor with adjustable trip and restart delays offers precise system protection for industrial applications. Its broad 190-480 VAC operating range and auto-ranging capability simplify integration into diverse electrical infrastructures. Users can configure trip delays from 1-30 seconds for voltage and unbalance faults, alongside adjustable restart delays from 1-500 seconds. This customization allows for tailored response to transient conditions, preventing unnecessary shutdowns while ensuring equipment safety. The monitor detects under and over voltage, voltage unbalance, and phase loss, safeguarding connected machinery. Dual SPDT output contacts provide flexible control options for alarms or contactor disengagement. Its robust design, with an operating temperature range of -20° to +140° F, ensures reliable operation in demanding environments, contributing to sustained operational uptime and equipment longevity.
