DAS-T Series (17А~105А)

Features:
  • three-phase controlled soft starter
  • easy mounting, also for retrofitting into existing systems
  • terminal arrangement suitable for switchgear connection
  • integrated bypass contactor
  • no mains neutral conductor (N) required
  • functional peak current reduction
  • monitoring of heat sink temperature
  • monitoring of motor temperature via motor thermistor
  • potential-free control inputs and outputs
  • special voltages up to 690V
  • robust metal enclosure
  • degree of protection IP 20
Functions:
  • soft acceleration and deceleration
  • acceleration/deceleration via control contact or control voltage 10 ... 42VDC (selectable)
  • 4 separately adjustable parameters starting torque, acceleration time, soft stop torque, deceleration time
  • potential-free output for operational status* 250VAC/8A
  • fault signalling contact (250VAC/8A)
  • input for motor thermistor
  • for special voltages higher than 500V an external electronic supply (230VAC) is necessary.

* closed when power semiconductors are bridged, or closed from start of acceleration to end of deceleration


Typical Applications:
pumps
