    Digital Bypass Starter III (DBSIII)

Default Alternative Text
An economical solution for new and retrofit industrial refrigeration applications
  • Solutions

    The new DBS III with the integrated Altistart 22/48 soft start/stop unit allows you to improve performance and provide stable operation for your refrigeration equipment.
  • Value Proposition

    The DBS III, a digital, solid-state, reduced-voltage combination motor starter, is an integrated solution for reduced-voltage starting and soft stopping of standard three phase asynchronous induction motors, plus, extends the useful life of the equipment while reducing KW energy demand.
  • Differentiation

    The DBS III starter reduces inrush current (with resulting voltage sag) as well as reducing mechanical shocks that can result from starting a motor across the line. Integrated control algorithms help ensure smooth rotation throughout the starting ramp without mechanical instability. Included within the DBS III starter is an integral shorting contactor to reduce steady-state motor operational losses.
