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, 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.
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.
Power range:
21 – 1600 A, 7.5 – 850 kW
(1.2 MW inside Delta Connection) Versions for 200 – 690 VAC
| Features | Benefits |
|---|---|
| AAC Adaptive Acceleration Control | – Automatically adapts to the chosen starting and stopping profile |
| Adjustable bus bars allow for both top and bottom entry (360–1600 A, 160–850 kW) | – Space saving, less cable cost and easy retrofitting |
| DC injection braking distributed evenly over three phases | – Less 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 of the application |
| Auto Reset | – Less down-time |
| Jog (slow-speed operation) | – Application flexibility |
| Second-order thermal model | – Allows motors to be used to their full potential without damage from overloading |
| Internal bypass contractors(21-215 A 7.5-110LW) | – Saves space and wiring compared to external bypass. Very little heat dissipates when running. Eliminates costly external fans, wiring or bypass contractors |
| Auto-start/stop clock | – Application flexibility |
| Compact size-amoungst 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 languages | – Serving the whole world |
