Stellar Soft Starters Provide 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 (45mm and 55mm). The microprocessor based 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 to 100%. A separate 24VDC 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.

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.
