Fuji Electric, VersiStart II (50~75A) series soft starters
Features:
  • two-phase controlled soft starter
  • controlled by microcontroller
  • optimized soft start
  • heatsink temperature detection
  • connection in the motor delta winding (cost saving via smaller rating)
  • current and torque reduction during acceleration
  • easy mounting, also for retrofitting into existing plants
  • integrated bypass relay
  • parameterization by means of four potentiometers
  • no additional control voltage required
  • no mains neutral conductor (N) required
  • economically priced substitute for star-delta starters
  • control outputs with spring-loaded terminals
  • compact design, 103 mm width
  • degree of protection IP20
Function:
  • soft acceleration and deceleration
  • potential-free control input for soft acceleration and deceleration
  • 4 separately adjustable parameters accel. time, start voltage, decel. time, max. start current
  • boost-start selectable
  • Motor PTC
  • current controlled start-up with external transformer (transformer is included in delivery)
  • potential-free control output for operating state, unit bypassed and failure

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