Littelfuse 460-100-SP Voltage Monitor Product Descriptions
The 460-100-SP is used on 95–120 V ac, 50*/60 Hz single-phase motors and the 460-200-SP is used on 190–240 V ac, 50*/60 Hz single-phase motors to protect them from damaging high and low voltage conditions. An adjustment knob allows the user to
set a 1–500 second restart delay. The variable restart delay is also a power-up delay and can be utilized to stagger-start motors on the same system.
A unique microcontroller-based, 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.
