SOFT STARTERS
Starting a AC Induction motor can be a stressful experience
for both the users power distribution system as well as the
mechanical system that is being powered by the motor.
Typical symptoms of across the line starting can include:
dimming of lights
wear on belts, couplings, motors
damage to end products
tripping of overload protection

To combat these problems, Reduced Voltage Soft Starters
were developed. Solid State Reduced Voltage Soft Starters
use power semiconductors called silicon controlled rectifiers(SCR) that block voltage in both directions in the off stage
and conduct voltage in one direction only in the on state.
By using a Current Controlled (Closed Loop) Soft Starter, we
can achieve a much smoother starting action because currentis directly proportional to torque, thus eliminating many
problems associated with using almost any other method of
starting AC motors.

Soft Starter or VFD?
Soft Starters are usually current or voltage controlled,
not frequency.
Soft Starters do not have the ability to control speed.
Soft Starters will have significant price benefits.
Soft Starters will have a smaller footprint on larger HP
application.

SAF SOFT STARTERS
Since 1976, SAF has developed Soft Starters that span over
three generations of technology. The dependable SR6 analog
unit, the compact versatile OPAL SS6, and the NEW
microprocessor-based OPAL Pro digital version. Even as our
products evolve, we have ensured to maintain the qualities
that have made every generation of SAFs Soft Starters a
success:
Reliability, Ruggedness and Simplicity.

SAF SOFT STARTERS
SAFs OPAL series was
built on the concept that our
customers wanted a reliable
starter that was simple to
use and had the flexibility to
match any application.
These ideas were kept in
mind when our customers
requested that we develop a
new digital starter.
