The PSR soft starter series includes the most compact soft starters and thus enables the design of compact starting devices. The system concept with motor protection switches and the products of the PSR series provides a significantly more compact starting solution than, for example, a star-delta starter. Integrated bypass contactors reduce energy losses and simplify the connection; setting up is child's play thanks to the limitation to just three potentiometers. The optimized ramp properties nevertheless ensure very smooth starting and stopping under all operating conditions. PSR with Us = 24V AC/DC
