Soft Start Controller with Auxiliary Contact
Description
The S701 device is a reduced voltage soft start controller
designed to control acceleration and deceleration of three-
phase motors. With the Auxiliary Contact Option, it is possible
to control an external bypass to reduce heating and lengthen
acceleration and deceleration times.
The S701 provides the user with the ability to adjust initial
torque, ramp up and down time, and also select kick start for
high inertia loads.
