MotorSaver™ Three-Phase Voltage Monitor 460 Series

MotorSaver™ Three-Phase Voltage Monitor

 

The MotorSaver™ Model 460 three phase voltage monitor is a microcontroller-based voltage and phase sensing circuit that constantly monitors three phase voltage to detect harmful power line conditions. When a harmful condition is detected, the output relay in the 3 phase monitor is deactivated after an adjustable trip delay time. The output relay reactivates after power line conditions return to an acceptable level for an adjustable restart delay time. If equipped with the manual reset option, an external normally open momentary reset switch must be closed to reactivate the output relay. The trip and restart delays prevent nuisance tripping due to rapidly fluctuating power line conditions. When integrated into a building automation system, BAS, the power monitor automatically senses whether it is connected to a 190-240 volt 60 Hz system, a 440-480 volt 60 Hz system, or a 380-416 volt 50 Hz system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480 volt AC. Other adjustments include a 1-30 second trip delay, a 1-500 second restart delay, and a 2% to 8% voltage-unbalance trip point adjustment.
