Description

Littelfuse 50R200 Voltage Monitor Product Description

Model 50R200 Single Phase Voltage Monitor has a voltage sensing circuit which constantly monitors the single phase power for a low voltage condition. Single phase motors on fans, compressors, air conditioners, heat pumps, sump pumps, and small conveyor motors are all applicable to the Model 50R. When a harmful condition is detected the MotorSaver's output relay is deactivated after the specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for the specified amount of time (Restart Delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

Littelfuse 50R200 Voltage Monitor Typical Applications

  • Fans
  • Compressors
  • Air Conditioners
  • Heat Pumps
  • Well Pumps
  • Sump Pumps
  • Small Conveyor Motors
