ALSTOM MVS3000-4001 Product Specification
1. Product Overview
The ALSTOM MVS3000-4001 is a high-reliability medium-voltage soft starter specialized in smooth motor startup and shutdown control, targeting applications including large centrifugal pumps, fans, compressors, and conveyor systems. Integrated with ALSTOM’s advanced thyristor control technology and intelligent current-limiting algorithms, this soft starter effectively reduces inrush current during motor startup (to ≤3 times rated current), minimizing mechanical shock to equipment and electrical impact on the power grid. It is widely deployed in thermal power plants, petrochemical refineries, water treatment plants, and mining facilities, where stable startup performance and equipment protection are core requirements.
Compliant with international standards such as IEC 61800-3 (medium-voltage adjustable speed drive systems) and IEEE 399 (power system analysis), the MVS3000-4001 maintains stable performance under grid voltage fluctuations and harsh industrial environments. Its modular design and comprehensive protection functions ensure reliable operation, while the user-friendly operation interface simplifies parameter setting and status monitoring.

3. Key Features
3.1 Gentle Startup & Equipment Protection
Adopting advanced thyristor phase-shift control technology, the MVS3000-4001 gradually increases the output voltage to the motor, effectively suppressing inrush current and reducing mechanical impact on motor bearings, shafts, and transmission components. This extends the service life of motors and associated equipment by 20% – 30%, especially suitable for large inertia loads like ball mill motors.
3.2 Multiple Startup Modes & Flexible Adaptation
Equipped with three startup modes (current-limiting, voltage-ramp, torque-controlled), users can select the appropriate mode based on load characteristics. For example, current-limiting mode is suitable for grid-sensitive scenarios, while torque-controlled mode is ideal for high-inertia loads. The adjustable startup time (1 s – 300 s) further enhances adaptation to different application requirements.
3.3 Robust Structure & Reliable Operation
The soft starter uses high-voltage thyristor modules with strong current-carrying capacity and a modular power cabinet design, ensuring stable operation under long-term working conditions. The built-in temperature monitoring and overheating protection functions prevent component damage caused by excessive temperature, while the dust-proof and moisture-proof housing design adapts to harsh industrial environments.
3.4 Convenient Monitoring & System Integration
The integrated LCD display provides real-time monitoring of key parameters such as startup current, voltage, and temperature. With standard Modbus and optional Profibus communication interfaces, it can be seamlessly connected to SCADA and DCS systems, supporting remote control, parameter modification, and fault diagnosis, which simplifies the management of large-scale motor control systems.
