Soft motor starter line
These soft starters are available in 5 A to 40 A sizes, are overcurrent protected and feature two DIN-rail mountable frame sizes: 45 mm and 55 mm. The microprocessor-based starters have an operating voltage range of 208 Vac to 460 Vac.
Stellar SR22 series soft starters are available in 5 A to 40A sizes, are overcurrent protected and feature two DIN-rail mountable framesizes: 45 mm and 55 mm. The microprocessor-based starters have an operatingvoltage range of 208 Vac to 460 Vac. Each unit is easily configurable andequipped with three potentiometers allowing adjustable start and stop times ofup to 30 seconds and an adjustable start pedestal voltage ranging from 30% to100%. A separate 24 Vdc control voltage is required.
The soft starters are suitable for applications such aspumps, blowers and conveyors. They use thyristors for controlled reducedvoltage motor starting and stopping, and then switch to internal contacts forefficient running at rated speed. When used instead of a line starter, the softstarters provide smoother control resulting in less shock as well as lesselectrical and mechanical stresses.
The soft starters are backed by a two-year warranty.Optional cooling fans are available to prolong the life of the soft starter.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
