Soft starter DM4

Application examples

  • The internal current limitation restricts the inrush current peaks when starting up motors of circular saws, band saws, agitators, mixers, grinders and crushers
  • Longer service life and less wear on fan and pump drives
  • Controlled start and stop of mechanical handling drives prevent damage to goods and premature wear on plant that is often spread over a large area
  • For use as three-phase voltage regulator of heating and lighting installations, as well as for inrush current limitation on transformers
