ALSTOM MVC3003-4003 Product Specification
1. Product Overview
The ALSTOM MVC3003-4003 is a medium-voltage variable frequency drive (VFD) engineered for industrial motor control applications, specifically tailored for high-power pumps, fans, compressors, and conveyors. Designed with ALSTOM’s proprietary pulse-width modulation (PWM) technology and robust power electronics, this VFD enables precise speed regulation of AC motors, optimizing energy efficiency while reducing mechanical stress on equipment. It is widely deployed in power generation, water & wastewater, mining, and cement industries, where reliable motor control and energy savings are critical.
Compliant with international standards such as IEC 61800-5-1 (adjustable speed electrical power drive systems) and IEEE 519 (power quality), the MVC3003-4003 ensures stable operation under fluctuating grid conditions and minimizes harmonic distortion, protecting both the drive itself and connected electrical systems.

3. Key Features
3.1 High Energy Efficiency
Adopting advanced vector control and optimized PWM algorithms, the MVC3003-4003 adjusts motor speed to match actual load demands, reducing energy consumption by 15% – 40% compared to traditional fixed-speed drives. This is particularly impactful for constant-torque applications like water pumps and fans, where load variations are common.
3.2 Robust Power Electronics
Equipped with high-voltage IGBT modules and a modular power unit design, the VFD offers strong overload capacity (110% rated load for 60 seconds) and resistance to voltage fluctuations. The modular structure also simplifies maintenance, as faulty units can be replaced without shutting down the entire system.
3.3 Flexible Control & Integration
Dual control modes (V/F and vector) cater to different application requirements: V/F control for simple speed regulation, and vector control for high-precision torque and speed control (e.g., in conveyor systems). Multiple built-in communication protocols enable seamless integration with SCADA and DCS systems, supporting remote monitoring and control.
3.4 Comprehensive Protection
A multi-layer protection system safeguards the VFD, motor, and connected equipment from electrical faults and environmental anomalies. Real-time monitoring of key parameters (current, voltage, temperature) triggers automatic protective actions, minimizing downtime and maintenance costs.
