VersiStart III (9A~45A)

Features:
  • three-phase controlled soft starter
  • controlled by microcontroller
  • optimized soft start and current control
  • connection in the motor delta winding (cost saving via smaller rating)
  • current and torque reduction during acceleration
  • easy mounting, for snap-mounting on 35 mm standard rail
  • integrated bypass relay
  • parameterization by means of potentiometers
  • no mains neutral conductor (N) required
  • economically priced substitute for star-delta starters
  • spring-loaded terminals
  • heat sink temperatur monitoring
  • compact design, 45mm up to 25A and 52,5mm at 45A
  • degree of protection IP20
  • motor protection
  • thermal device protection
Function:
  • soft acceleration and deceleration
  • potential-free control input for soft acceleration and deceleration
  • separately adjustable parameters accel. time, start voltage, decel. time, current limiting, rated device current and tripping class
  • boost-start selectable
  • potential-free relay output for operating state
  • transistor output — unit bypassed

Typical Applications:
door and gate drives
pumps, ventilators, fans
conveying systems, packaging machines
transport systems, assembly lines, machine application


Options (upon request):

  • special voltages 230V and 480V
  • wide voltage range 200-480V with external control supply voltage US 230VAC (B)
  • signalling contact (M)beginning of acceleration until end of deceleration
