Description
The Model 2581 3-Phase Monitor
is designed to continuously monitor 3-phase power lines for
phase loss, low voltage and phase reversal. The Model 2581
Monitor will detect phase loss on a loaded motor even when
regenerated voltage is present.
This device consists of
a solid-state voltage and phase-angle sensing circuit, driving
an electromechanical relay. When correct voltage and phase
rotation are applied, the internal relay will energize.
A fault condition will de-energize the relay. When the fault
is corrected, the monitor will automatically reset .
The Model 2581 3-Phase Monitor
does not require a neutral connection and can be used with
Wye or Delta configured systems. Low voltage trip point
is factory set at 10% below nominal. An LED indicator is
provided for system troubleshooting.
