The PSR softstarter is the most compact of all the softstarter ranges, thereby making it possible to design compact starting equipments. The system concept with manual motor starters and the psr provides a far more compact starting solution than for in stance a star delta starter. Built-in by-pass reduces the energy loss and makes the connection easier and with only three potentiometers, the set-up couldnt be any easier. Still, the optimized ramping characteristics will ensure a very smooth start and stop for all applications. Recommended MS450 28 - 40
For Stopping Pumps: Even Without Using Torque Control, The PSR Range Is Designed To Reduce Water Hammering And Will Allow A Superior Stop Compared To The Direct Stop Resulting From A Star Delta Starter Or A DOL Starter
