MVW01 – Medium Voltage Variable Speed Drive

WEG introduce the third generation of Medium Voltage Variable Speed Drives MVW01 G3 offers power arms with a new cooling system and an electrical panel with a new thermal dissipation design that allows a greater range of power output.

This series of WEG Frequency Inverter uses MV IGBTs that offer greater efficiency, greater robustness and better protection for the MV motor.

Friendly operator interface with 10” “touch screen” HMI provide the operator an easy interaction to program the drive, access and read the parameters, configure the exhibition mode (letter size, languages, colour, etc.), create graphics and also, by means of pop-up windows, see text messages as alarms, trips, error logs, help, etc.

MVW01 G3 is applicable for a wide range of industrial applications that need variable speed such as compressors, pumps, fans, conveyor belts, mills, etc. for new or existing installations, the MVW01 G3 is an efficient and reliable solution that in addition to allowing process speed control, also offers energy saving reduced operational costs.

System Customized Solutions

WEG customized solutions are based on standard VSD designs and experience gained through the supplying of a demanding a variety of applications.

Water Cooled Version

MVW01 water-cooled version is perfect for high power and demanding applications, such as environments with harsh conditions. It is also the ideal solution when hot air cannot be dissipated and air-conditioning is not a viable solution commercially.

Double independent water circuit consisting of internal closed loop, internal water-to-water heat exchanger and external water circuit, provides MVW01 a high efficiency cooling system to dissipate the losses away from the electrical room.

Reliable water circuits using quick release water connectors with retention avoids undesirable water drops inside the panel even in case of maintenances and redundant pumps to guarantee the continuous operation of the cooling system.

No special treatment for the external water is required.

Testing Facility

Every equipment manufactured is tested in our labs. This guarantees the performance and saves time during commissioning and start-up.

The tests of WEG MV VSD will be conducted in accordance with the following standards: IEC 60146-1, 61800-3, 61800-4 and 61800-5.

• Routine tests: Visual Inspection, insulation, dielectric voltage-withstand, light load, checking of auxiliary devices, checking the control equipment properties and checking the protective devices.
• Type tests: paint plan, rated load, temperature rise and efficiency / power losses.
• Special tests: power factor, overload / overcurrent capability, harmonic distortion and ground fault test.

Routine tests, type tests and combined/string tests (VSD + Motor) can be performed in the same manufacturing plant. Please consult WEG for further information.
