Soft Starters MCD500
Rp. 0,00
Where variable speed is not required, electronic soft starters still provide benefits compared to star/delta and other contactor solutions. 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.
Features and benefits
Power Range
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.
Start and stop
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.

Features and benefits
The MCD 500 provides superior protection, fully adjustable to the actual needs, enabling increased reliability, uptime and equipment lifetime expectancy.
Features-benefits
• 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
