| Model 202 Three Phase Voltage Monitor |
| Series Description: Model 202 is an auto-ranging voltage monitor designed to protect three-phase motors regardless of size. It is used on 190-480 VAC, 50 to 60 Hz motors to prevent damage caused by single phasing, low voltage, high voltage, phase reversal, or voltage unbalance. A unique microcontroller-based voltage and phase sensing circuit constantly monitors the three phase voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver's output relay is deactivated after a trip delay. The output relay reactivates after power line conditions return to an acceptable level for the selected amount of time (Restart Delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. |
