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.
