Series Features
50R Series - Single-Phase Voltage Monitor
Series Description: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® deactivates its output relay 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.
Series Applications:Fan motors, Air conditioners, Compressors, Heat, well, and sump pumps, Small conveyer motors
Proprietary voltage sensing circuitry: Constant monitoring of single-phase power for a low-voltage condition
Adjustable trip delay (-3 models) and restart delay (-2 models) settings: Prevents nuisance tripping due to rapidly fluctuating power line conditions, allows staggered start-up of multiple motors after a fault
High-voltage detection (-9 models): Trips and resets at a fixed percentage of the setpoint: trip 110%, reset 107%
600 V rated relay contacts available on some models: Eliminates the need for a control transformer to step voltage down to 120–240 V for a control circuit
