VLT® Compact 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...

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.

VLT® Compact Starter MCD 100
MCD 100 is a cost effective and extremely compact soft starter for AC motors up to 11 kW, due to a unique semiconductor design. MCD 100 is a true “fit and forget” product...

Product Range
1.5 kW (MCD 100-001)
7.5 kW (MCD 100-007)
11 kW (MCD 100-011)

All sizes are rated for line voltage up to 600 V AC.

Main Features
MCD 100 products provide timed voltage ramp up and down.
Ramp time can be individually adjusted with rotary switches from 0.4 to 10 seconds.
The start torque can be adjusted from 0 to 85% of the direct on-line torque.
Main Benefits
A robust semiconductor design – selection can be based on motor power which ensures easy selection. Can be used for an almost unlimited number of starts per hour without derating. An universal control voltage
(24-480 V AC / V DC) – simplifies selection and keeps stock at a minimum. A “fit and forget” contactor design – simplifies installation and reduces required panel space. Digitally controlled rotary switches – secure precise settings and simplify installation.
Ratings for heavy duty as standard – simplify selection and reduce the risk of breakdown.
