The DSP-1LM Phase Monitor offers an affordable, high quality solution to provide protection from phase loss, phase unbalance and phase reversal for your motors, compressors, pumps, ventilators or any other type of 3-phase electrical equipment. This is a 3-in-1 monitor, phase loss monitor, phase reversal monitor, phase unbalance monitor. The Controlab three phase monitor is sometimes compared to a smart fuse or to an intelligent protection relay, it continuously monitors the voltage level and phase-angle on each phase of your electrical supply. If a phase failure (single phasing) occurs, the DSP-1LM 3 Phase Monitor will immediately open the control circuit of the protected equipment, thus preventing damage. When the voltage returns to normal, the three-phase DSP-1LM monitor resets itself and closes the control circuit, allowing the protected equipment to be started normally and safely.
