Description

Time Mark 2581-460The 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
