The PSS is the most flexible of the four softstarter ranges from ABB. It allows both in-line and inside delta connections. It is the ideal solution when looking for a robust solid state starting solution where many starts per hour are required. The setup of the PSS softstarter is easily done using the three rotating switches to adjust the start and stop and the dip switch to select between in-line or inside-delta connection.
