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 the products of 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 connections, while the setup is made easy with only three potentiometers. The optimized ramp characteristics ensure very smooth starting and stopping under all operating conditions. PSR with Us = 24V AC/DC.
