描述 Description

The 201-xxx-DPDT Series is an 11-pin octal base plug-in voltage

monitor designed to protect 3-phase motors regardless of size.

The 201-100-DPDT is used on 95–120 V ac, 50/60 Hz motors and

the 201-200-DPDT is used on 190–240 V ac, 50/60 Hz motors

to prevent damage caused by incoming voltage problems. The

units feature two isolated sets of contacts that are ideal for use

with two control circuits with different voltages.

The unique microcontroller-based voltage and phase-sensing

circuit constantly monitors the voltages to detect harmful

power line conditions When a harmful condition is detected, the

MotorSaver’s output relays are deactivated after a specified trip

delay. The output relays reactivate 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 unit is also available with a shorter trip delay and faster

restart delay. The 201-xxx-DPDT-60mS has a trip delay of 0.5

seconds and a restart delay of 60 milliseconds.
