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. Adaptive Acceleration Control means, that for each start and stop, the soft starter compares and adapts the process to the chosen profile fitting 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.
The perfect solution, also for more severe applications:

  • vlt500_0001Pumps
  • Conveyors
  • Fans
  • Mixers
  • Compressors
  • Centrifuge
  • Mill
  • Saw
  • And many more Power range 21 – 1600 A, 7,5 – 800 kW
    (1,2 MW inside Delta Connection) Versions for 200 – 690 VAC
Features Benefits
. AAC Adaptive Acceleration Control . Automatically adapts the the best starting and stopping profile for the application
. Adjustable Bus Bars, allow for top, bottom or both (>=360A) . Space saving, reduced cable cost and easy retrofitting
. DC injection braking distributed evenly over three phases . Reduced installation cost and less stress on the motor
. Inside Delta (6-wire connection) . Smaller soft starter can be selected for the application
. Log Menus, 99 Events and Trip log provide information on events, trips and performance . Eases analysis on the application
. Auto Reset . Less down time
. Jog (slow-speed operation) . Application flexibility
. Second-order thermal model . Allows motor to be used to its full potential without damage from overloading
. Internal bypass contractors (<=110kW) . Saves space and wiring compared to external bypass . Very little heat dissipates when running Eliminates costly external fans, wiring or bypass contactors
. Auto-start/stop clock . Application flexibility
. Compact size-amongst the smallest in their class . Saves space in cabinets and other application setups
. 4-line graphical display . Optimum programming approach and setup for viewing operational status
. Multiple programming setup (Standard Menu, Extended Menu, Quick Set) . Simplifies the programming, but still holding to maximum flexibility
. Multiple (8) languages . Serving the whole world
