ALSTOM MVC3003-4025 Product Specification
1. Product Overview
The ALSTOM MVC3003-4025 is a cost-effective medium-voltage variable frequency drive (VFD) tailored for mid-to-high power industrial motor control, focusing on applications such as medium-sized centrifugal pumps, forced draft fans, reciprocating compressors, and heavy-duty conveyors. Integrated with ALSTOM’s mature pulse-width modulation (PWM) technology and optimized control algorithms, this VFD realizes reliable speed and torque regulation of AC motors, balancing energy efficiency and operational stability while controlling equipment costs. It is widely applied in regional thermal power plants, petrochemical auxiliary systems, municipal water treatment plants, and non-ferrous metal processing facilities, where cost-performance and steady operation are core demands.
Complying with international standards including IEC 61800-5-1 (adjustable speed electrical power drive systems), IEEE 519 (power quality), and IEC 61000-4 (electromagnetic compatibility), the MVC3003-4025 maintains consistent performance under normal grid fluctuations and general industrial environments. Its basic harmonic suppression function reduces grid impact, ensuring safe operation of the drive system and associated electrical equipment.

3. Key Features
3.1 Balanced Energy Efficiency & Cost Performance
Adopting ALSTOM’s optimized PWM algorithm and practical control strategy, the MVC3003-4025 maintains favorable efficiency even at partial loads (≥94% efficiency at 30% load). It adjusts motor output according to load variations, reducing energy consumption by 15% – 35% compared to traditional control methods, which is suitable for medium-load applications like municipal water supply pumps and power plant auxiliary fans.
3.2 Reliable Performance & Flexible Configuration
Equipped with mature high-voltage IGBT modules, the VFD provides stable overload capacity (110% rated load for 60 seconds) to adapt to occasional load surges. Its flexible configuration allows users to select control modes (V/F or vector) and optional functions based on actual needs, avoiding unnecessary cost input while meeting basic control requirements.
3.3 Simplified Maintenance & Basic Diagnostics
The compact modular design simplifies installation and maintenance, with key components easily accessible for replacement. The built-in basic diagnostic system monitors critical parameters (current, voltage, temperature) in real time, triggering alarm signals for faults to help maintenance personnel locate issues quickly, reducing maintenance time and costs.
3.4 Easy Integration & Standard Safety
Common communication interfaces (Modbus, Profibus) enable seamless connection with mainstream SCADA and DCS systems, supporting basic remote monitoring and control. It meets international safety standards, with essential safety designs such as overcurrent protection and insulation monitoring, ensuring safe operation in general industrial environments.
