DUOSTART Series (3,5А~12А)

Features:
  • two-phase controlled soft starter
  • easy mounting, also for retrofitting into existing plants
  • integrated bypass relay
  • no mains neutral conductor (N) required
  • parameterization by means of three potentiometers
  • economically priced replacement for star/delta switches
  • for mounting on top hat rail
  • current reduction during acceleration
  • very compact design, overall width from 45mm on
  • degree of protection IP20
Functions:
  • soft start and soft stop
  • potential-free control input for soft start and soft stop
  • 3 separately adjustable parameters starting torque, acceleration time, deceleration time
  • control (start/stop) with contact or voltage 10-42VDC

Typical Applications:
door and gate drives
pumps, ventilators
conveyors
packaging machinery
transformer soft start


Options (upon request):

  • DUOSTART ... M (beginning of acceleration until end of deceleration)
  • DUOSTART ... S control (start/stop) with voltage 10-42VDC
  • external 24V supply voltage (wide voltage range capability)

Upon request up to 500kW
N = without bypass (Integrated Bypass by mid year ´10)
