Soft motor starter line
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.
