MVW01

Representative Image Only

The third generation of the MVW01 offers power arms with a new cooling system and an electric panel with a new thermal dissipation design that allows a greater range of power output when compared to the previous version.

The MVW01 third generation also introduces the new 10” touchscreen HMI that provides the operator an easy interaction to program the drive, access and read the parameters, configure the exhibition mode (letters size, idioms, colors, etc.), create graphics and also, by means of pop-up windows, see text messages as alarms, trips, error log, help, etc.

Applied for a wide range of industrial applications that require variable speed control, such as compressors, pumps, fans, conveyor belts, mills, etc. or to start high power motors (synchronous or asynchronous).

The MVW01 third generation is an efficient and reliable solution that not only enables process speed control but also provides energy savings, high efficiency, reducing operation & maintenance costs as well as the total cost of ownership (TCO).

Main characteristics

  • Motor voltage: 2.3 kV to 6.9 kV;
  • Power range: 500 to 49.000 HP (400 kW up to 36 MW);
  • Protection degree: IP21, IP41, IP42 or IP54 (available on Water cooled version).

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.
