Softstarter, 0050957, DOLD

The 0050957 is a softstarter designed to enable 1-phase or 3-phase induction motors to start smoothly. This product slowly ramps up the current on two phases, therefore allowing the motor torque to build up slowly. This reduces the mechanical stress on the machine, prevents damage to conveyed material and limits the start current. When the motor is up to full speed the semiconductors in this is bridged to prevent internal power losses and heat build up.

Features

• Softstart and softstop function
• Acceleration and deceleration time resp. starting and switch-off torque are separately adjustable
• Wide input voltage range of the power semiconductors
• Integrated overtemperature monitoring
• LED indication

Applications

• Motor with gear, belt or chain drive
• Fans, pumps, conveyor systems, compressors
• Packaging machines, door-drives
• Start current limiting on 3-phase motors
