VLT 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.Selection can be made on the basis of the motor power – exactly as with traditional contactors.
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.
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.
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.
VLT MCD 200
Due to extensive use of the latest technology, such as new semiconductor control algorithms and bypass design, the new soft starters are very compact and heat dissipation very low.
There is no need for extra ventilation or bypass contactors. This simplifies installation and keeps panel space at a minimum.
7.5 – 110 kW
MCD 201 is the basic version offering timed voltage ramps
MCD 202 is the advanced version providing current limit soft start, timed voltage ramp down, and motor protection.
Current ratings for normal and heavy starting
Versions for 200- 575 V AC
Voltage ramps or current limit ramp soft start
Built-in motor protectionCompact design with internal bypass system for minimum power loss
Add on modules for remote operation and serial communication
Software for sizing, control and monitoring.
VLT MCD 500
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.
The MCD 500 provides superior protection, fully adjustable to the actual needs, enabling increased reliability, uptime and equipment lifetime expectancy.
• Adjustable bus bars allow for both top and bottom entry (360-1600 A, 160-850 kW) – Reduced installation cost and motor stress.
• Inside Delta (6-wire connection) – Smaller soft starter can be selected.
• Log menus, 99 events and trip log – eases analysis.
• Second-order thermal model – allows motors to be used to their full potential without damage from overloading.
• Internal bypass contactors (21- 215 A – 7.5-110 kW) – saves space & wiring, low heat dissipation when running, eliminates external fans.
• Auto reset – reduces downtime
• Auto-start/stop clock – application flexibility¨
• Compact size, amongst the smallest in their class – saves space in installation.
