VLT Soft Starter

The compact VLT Soft Starter MCD 500 is a total motor starting solution. Current transformers measure motor current and provide feedback for adaptive control of motor ramp profiles.

21 - 1600 A, 7.5 – 850 kW 
(Versions for 200 – 690 VAC) 
To make programming easy, the VLT Soft Starter MCD 500 has a four line, multi language graphical display and a logical keypad. This enables advanced setup and viewing of operational status. Three menu systems: Quick Menu, Application Setup and Main Menu provide optimal programming flexibility and ease of use. 
AAC, Adaptive Acceleration Control, automatically employs the best starting and stopping profile for the application. This means that for every start and stop, the soft starter compares and adapts the process to the chosen profile best suited to the application. 

Starting: 
• AAC adaptive acceleration control 
• Current ramp 
• Constant current 
• Kickstart 
Stopping: 
• Coast to stop 
• TVR to stop 
• AAC adaptive deceleration control 
• Brake 
Outputs 
Three output relays, 1 programmable. Analogue output motor thermistor.
