Medium - Voltage Soft Starter
This third generation, fiber optic controlled, medium-voltage soft starter is designed for use with standard asynchronous and synchronous motors.
The soft starter is a highly sophisticated digital soft starter which ensures smooth, stepless acceleration and deceleration, eliminating current and mechanical shocks on motor and load. It may be supplied as a chassis or enclosed type with a multiple range of options.
