| Delta Medium Voltage Drive |
|
| Why Delta MVD |
 Drives can save an average of 40% of the electricity a motor uses as well as reduce related CO2 emissions. Since industry accounts for one-third of the world's electricity consumption and electric motors consume 65% of industrial electricity in regions such as the EU [1], the potential global energy savings from a wider use of drives would be substantial. For an industrial enterprise drives can reduce energy costs, minimize wear on motors and other equipment, and reduce maintenance costs. A reliable, high-performance drive such as Delta's MVD-1000 medium voltage drive can provide an enterprise with greater energy-savings as well as increased productivity.

| Feature and Benefit |
Leading Technology
‧Multi-pulse input rectification reduces input current harmonic distortion, meeting IEEE 519-1992
‧Advanced drive concept provides multilevel output voltages and enhanced motor operation
Enhanced Process & Quality Control
‧A built-in PID controller enhances control of process variables such as flow and pressure
‧Ride through and flying start features ensure a more continuous process in spite of input voltage dips
‧Easily integrated with customer's upper level control
Lower cost of ownership
‧Reduced power loss maintains overall efficiency above 96% and minimizes operating costs over the drive's life cycle
‧Optimized pump and fan operation ensures significant energy savings and shortens the return on investment
‧Integrated transformer enables a three-cables-in-three-cables-out installation concept using considerably less engineering effort
‧Reduced mechanical stresses eliminates hammer effect in pipelines and vent ducts, and lowers maintenance cost
‧Multilevel voltages, controlled start-up, and smooth response to load step minimize motor stress |
|
| Reliability & Certification |
| Delta provides quality assurance through rigorous inspection and testing based on international standards. To ensure that the motor drive operates as predicted upon start-up, Delta Electronics has built a state-of-the-art-multi-megawatt test facility for full load capacity and burn-in verification. A detailed test procedure reduces start-up time during installation and commissioning in the field. |
