The 50R series is a single-phase voltage monitor with a voltage-sensing circuit that constantly monitors the single-phase power for a low-voltage condition. When a harmful condition is detected, the MotorSaver's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level and a specified amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. This monitor is used in a variety of applications such as compressors, air conditioners, heat pumps, well pumps, sump pumps, and small conveyer motors.

功能与特色

  • Proprietary voltage sensing circuitry
  • Adjustable trip delay (-3 models) and restart delay (-2 models) settings
  • High-voltage detection (-9 models)
  • 600 V rated relay contacts available on some models
