The PSR series of soft starters includes the most compact soft starters, enabling the design of compact starting devices. The system concept with motor protection switches and products from the PSR series provides a significantly more compact starting solution than, for example, a star-delta starter. Integrated bypass relays reduce energy losses and simplify the connection, while setup is incredibly easy thanks to the limitation to just three potentiometers. The optimized ramp characteristics ensure very smooth starting and stopping under all operating conditions.
