Description

Should the monitored voltage fall below the set point level Umin, the protector will trip and the red LED will illuminate to indicate the fault condition. During the time delay period the red LED will flash for the set time (t) before the relay deenergises. The protector will automatically reset once the monitored voltage rises above the set point level Umin plus the differential (between 1-15%) causing the red LED to extinguish and the relay to make without time delay. Should the voltage fall below the value of opening level Uoff the protector under red LED will flash indicating a status of low nominal voltage causing the relay contact to return to original status.
