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.
