TECHNICAL DATA

LSMV Series – Medium Voltage Drives for Energy Efficiency

Three-phase | 140 to 9,130 kW

Perfect Energy-Saving Medium Voltage Drive

Key Features

  • Multi-Level Pulse Width Modulation (PWM) Technology:

    • More sinusoidal output waveform, eliminating the need for output filters
    • Low input current THD, fully compliant with IEEE standards

  • Compact Design:

    • Optimized internal layout through thermal analysis to maximize space efficiency

  • High Efficiency & Energy Saving:

    • Efficiency and power factor above 95%, without compensation devices
    • No input/output filters required, achieving perfect energy-saving VFD system

  • Redundant Cell Power Factor Control:

    • No additional cost for low power factor correction
    • Advanced voltage regulation and stable high power factor maintained across the entire speed range using standard induction motors (above 95%)

  • Built-in Cell Bypass Function:

    • In case of cell failure during operation, the faulty cell is bypassed automatically or manually
    • After bypass, the system can still deliver 83% of the rated voltage
    • Neutral point shifting ensures continued operation with constant drag torque, even with a bypassed cell
