The 201-SP series is an 8-pin octal-base, plug-in voltage monitor designed to protect single-phase motors regardless of size. The 201-100-SP is used on 95–120 V ac, 50/60 Hz motors to prevent damage caused by low voltage. The 201-200-SP is used on 190–240 V ac, 50/60 Hz motors. The 201-200-SP-T-9 is a pin-for-pin replacement for a Time Mark® #260 series voltage monitor. High voltage protection is included in the 201-200-SP-T-9. The unique microcontroller-based voltage and voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. 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.
