VLT® Soft Starter MCD 500

VLT® Soft Starter MCD 500 is a total motor starting solution.
Current transformers measure motor current and provide feedback for controlled motor ramp profiles.
AAC, the Adaptive Acceleration Control automatically employs the best starting and stopping profile for the application.

Features and benefits

Power range 
21 – 1600 A, 7,5 – 800 kW
(1,2 MW inside Delta Connection) Versions for 200 – 690 VAC

AAC, the Adaptive Acceleration Control automatically employs the best starting and stopping profile for the application. Adaptive Acceleration Control means that for each start and stop, the soft starter compares and adapts the process to the chosen profile best suited to the application.

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.
