Automation Direct Stellar Soft Starters
AutomationDirect introduces Stellar soft starters, the newest addition to their product offering, as a low-cost motor control alternative. The SR22 series soft starters, available in 5A to 40A 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 to 460 Vac. Each unit is equipped with three potentiometers allowing adjustable start and stop times of up to 30 seconds, and an adjustable start pedestal voltage ranging from 30% to 100%. A separate 24 VDC control voltage is required.

Ideal for applications such as pumps, blowers and conveyors, the SR22 series soft starters use thyristors for controlled reduced voltage motor starting and stopping, and then switch to internal contacts for efficient running at rated speed. When used instead of a line starter, Stellar soft starters provide smoother control resulting in less torque, less shock, and less electrical and mechanical stress, according to the company.

Backed by a two-year warranty, Stellar soft starters prices start at $145. To prolong the life of the soft starter, optional cooling fans are available.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
