The perfect solution, also for more severe applications:• Pumps• Conveyors• Fans• Mixers• Compressors• Centrifuge• Mill • Saw• And many more

Power range 7.5 – 800 kWVersions for 200–690 VAC

VLT® Soft Starter MCD 500 is a total motor starting solution. Current transformers measure motor current and provide feedback for controlled motor ramp profiles.

The VLT® Soft Starter MCD 500 has a four line graphical display and a logic keypad making programming easy. Advanced setup is possible displaying operational status.

Three menu systems: Quick Menu, Application Setup and Main Menu provide optimum programming approach.

AAC, the Adaptive Acceleration Control automatically employs the best starting and stopping profile for the application.

Adaptive Acceleration Control means, that at each start and stop, the soft starter compares the actual curve with the one defined as preferred, and adjusts its performance next time.

Features Benefits

• AACAdaptiveAccelerationControl • Automatically adapts to the best starting and stopping profile for the application

• AdjustableBusBars,allowfortop,bottom or both (>=360A)

• Space saving, reduced cable cost and easy retrofitting

• DCinjectionbrakingdistributedevenly over three phases

• Reduced installation cost and less stress on the motor

• InsideDelta(6-wireconnection) • Smaller soft starter can be selected for the application
