MS6 REDUCED VOLTAGE STARTER

1 MS6 GENERAL DESCRIPTION

1.1 OVERVIEW

The Opal Pro series is a processor controlled line of solid state reduced voltage starters for use

with 3 phase induction motors. This series also includes various communication options,

which can be easily added to connect to standard industrial networks.

A solid state starter provides a step-less, smooth current ramp to the motor. This characteristic

eliminates current surges and mechanical torque transients. Since these units are solid state, we

now eliminate the maintenance of moving contacts, which are involved in almost any other

method of starting an AC induction motor.
