Description

Time Mark 2501-208The Model 2501 3 Phase Monitor is designed to continuously monitor 3 phase power lines for abnormal conditions. This device features solid state voltage and phase angle sensing circuits, which drive a SPDT electromechanical output relay. When the correct voltage and phase sequence is applied to a specified Model 2501, the output relay will energize. An under voltage, phase reversal, phase unbalance, or phase loss condition will cause the output relay
