Delta: Medium Voltage Drive (MVD1000 Series) 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 MVD1000/MVD2000/MVD3000 medium voltage drive can provide an enterprise with greater energy-savings as well as increased productivity.

Delta medium voltage drive is a high-efficiency, compact, high reliable and energy-saving solution. According to demand of different motors and loads, Delta provides general type and vector control type MVDs, which have a broad range of applications in segments such as power generation, oil & gas, mining, metals, cement, and public facilities. MVD is used to drive medium voltage motors loaded for instance by fans, pumps, compressors, mills, crushers, mixers, and extruders. MVD provides process control, so it can increase production efficiency, reduce energy loss, improve equipment protection, and reduce maintenance cost.
Delta provides customers complete solutions with easily operated variable frequency drives. Advanced control functions enhance adaptability against instable grid Multi-pulse input rectification reduces input current harmonic distortion, meeting IEEE 519-1992 Advanced drive concept provides multilevel output voltages and enhanced motor operation
Overcurrent Overload Transformer over temperature MVD over temperature Under voltage / over voltage Motor overload (external) Blower fault High voltage cabinet door open Cabinet air pressure abnormal Output short circuit Input / output phase loss Communication fault Output fault to ground
Enhanced Process & Quality Control Built-in proportional integral differential (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 Friendly user interface provide easy-to-use system integration
Control & Monitoring Features Frequency reference (Hz) Actual frequency (Hz) Input / output power / current / voltage Cumulative operating hours Drive status Status of system bypass switches and MCB Analog inputs / outputs monitoring Fault / Alert messages Fault diagnosis function Ride-through and flying start functions
System efficiency is more than 98.5% (without phase-shifted transformer) Optimized pump and fan operation ensure significant energy savings and short return on investment Integrated transformer enables a three-cable-in-three-cable out installation concept using considerably less engineering effort Reduced mechanical stresses eliminate hammer effect in pipelines and vent ducts, and lowers maintenance cost Multilevel voltages and motor soft start minimize stresses
