For a low-cost alternative for motor control, this series of soft
starters is available in 5A to 40A sizes, are overcurrent protected and
feature two DIN-rail mountable frame sizes (45mm and 55mm). Prices
start at $145.
AutomationDirect Stellar microprocessor-based soft starters have an operating voltage range of 208 to 460 VAC. Easily configurable, 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 percent to 100 percent. A separate 24 VDC control voltage is required.
Designed 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 an across-the-line starter, Stellar soft starters provide smoother control resulting in less torque, less shock, and less electrical and mechanical stress.
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 starting at $45.
