Description
1PH PLUG IN VOLT MONITOR
The 201-xxx-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 micro controller-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.
