VersiStart II (3,5A~16A)

Features:
  • two-phase controlled soft starter
  • controlled by microcontroller
  • optimized soft start
  • current and torque reduction during acceleration
  • easy mounting, for snap-mounting on 35mm standard rail
  • integrated bypass relay
  • parameterization by means of three potentiometers
  • no additional control voltage required
  • no mains neutral conductor (N) required
  • economically priced substitute for star-delta starters
  • compact design, 45mm
  • degree of protection IP20
Function:
  • soft acceleration and deceleration
  • potential-free control input for soft acceleration and deceleration
  • 3 separately adjustable parameters accel. time, start voltage, decel. time
  • boost-start selectable
  • potential-free relay output for operating state - unit bypassed — and failure (optional)

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


Options (upon request):

  • special voltages 230V and 480V
  • wide voltage range 200-480V with external control supply voltage US 24VDC (B)
  • signalling contact (I) bypass and failure
  • motor-PTC (I)
  • current control (standard at VS II 400-16) (I)
  • heat sink temperature monitoring (I)
  • √3 — connection (cost saving via smaller rating)
  • signalling contact (M) (beginning of acceleration until end of deceleration)
