Soft starter

DAS-T [7,5 - 55kW]

Function Soft starter:

• 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

Properties Soft starter:

• 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

Typical applications:

pumps
ventilators
conveying machinery
dryers
washing machines
compressors cranes
trolleys
