MVW01 – Medium Voltage Drive

The MVW01 G4 (IoT Ready), WEG’s medium-voltage frequency inverter, was designed to meet the demands of electric motor control in applications with power up to 55,520 HP and voltages up to 6.9 kV. Featuring cutting-edge technology with high-voltage IGBTs, it uses NPC and HNPC topologies, along with flexible air and water cooling systems. It ensures high operational safety with protections against electrical arcs and an optional arc-resistant enclosure.

Equipped with a 10-inch touchscreen HMI interface, the MVW01 G4 offers seamless interaction for programming and real-time monitoring. Connectivity with major communication protocols, including EtherNet/IP, Profinet, Modbus-TCP, and MQTT, is supported. Additionally, it integrates directly and securely with the WEG Motion Fleet Management platform, providing intelligent asset management and predictive maintenance.

Rigorously tested in WEG laboratories and compliant with safety and efficiency standards, the MVW01 G4 ensures high reliability for critical high-power applications. A symbol of efficiency, robustness, and safety, it meets the needs of various industries, promoting energy savings, reducing operational costs, and reinforcing WEG’s commitment to sustainability.

Main Characteristics

Main Reasons to Use the MVW01

  • Voltage Source Inverter (VSI) featuring NPC topology;
  • Latest generation of power semiconductors that allow a durable replacement market;
  • Air or water cooling system;
  • State-of-art MV-Drives Technology;
  • High reliability due to proven design and low number power components;
  • Efficiency higher than 98,5% (low losses and high power factor in all speed range);
  • Customized lineup design (integrated or external transformer, back-to-back configuration, AFE input)
  • External transformer ensure optimized project layout that allows to reduce the size of the electrical room (lower costs with civil works and with the HVAC system);
  • High robustness against short circuit and overcurrent for MV motor;
  • Choose the water-cooled version for aggressive environments with high temperatures, high concentration of contaminating particles or where air conditioning is not a viable option.

 

User-friendly HMI

10-inch touch screen HMI mounted on the MVW01 door offers great flexibility to the operator allowing easy access to user process data in real time. The intuitive operation makes the tasks of parameterizing the equipment, reading status and recording alarms / faults simpler.

It also supports multiple languages, various levels of protection against unauthorized access as well as graphing and plotting functions.
