Description
Distinctive features:
Functions:
- 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
Distinctive 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 temperature monitoring
- compact design, 45mm up to 25A and 52,5mm at 45A
- degree of protection IP20
- motor protection
- thermal device protection
