Carlo Gavazzi RGTS Soft Starter Overview

Soft Starters are used in conjunction with electrical motors to alleviate the mechanical and electrical stress resulting from sharp rise in torque and sudden inrush current. Shielding the system from the latter in particular can extend the motor’s lifetime while preventing damage to the cables, shaft, and distribution network.

The Carlo Gavazzi RGTS is a 1-phase solid state soft starter designed for two-wire AC induction motors. Control is provided through built-in potentiometers that can be used to limit the motor ramp-up time and the initial torque buildup. An overview of the features is as follows:

Operation

A voltage ramp algorithm is utilized for the starter’s working, with the user having the option to adjust two independent settings, namely:

By setting the initial torque at a lower value results in a decreased output voltage, while the ramp-up time decides how long it will take for the output voltage to reach the full-load value.
