Altivar 71Q

Water-cooled drives for heavy duty industry from 90 to 630 kW

Improved robustness and efficiency with water cooling

Altivar 71Q
  • Features

    Altivar 71Q is a variable speed drive with water cooling from 90 to 630 kW. It is used in harsh environments, when drives with particular robustness are required. The integrated liquid cooling permits optimal dissipation of the lost heat from the power part and therefore optimizes the encapsulation of the whole electrical drive unit.

    • 3-phase 380 to 480 V from 90 to 500 kW
    • 3-phase 500 to 690 V from 110 to 630 kW
    • Control, operation, programming and the options are absolutely identical to the air-cooled devices Altivar 61 and Altivar 71
    • Multi-pump card for controlling up to 5 pumps
    • Communication cards (ProfiBus DP, Modbus TCP, Daisy Chain and Plus, DeviceNet, Ethernet, Interbus, CC-Link, etc.)
    • Programmable controller cards
    • Specific I/O for application functions
    • Encoder interface cards
    • Integrated EMC filter
    • Use in an open or closed cooling circuit possible
    • Reliable operation also when industrial water or fresh water is used for cooling
    • Wide temperature range of the coolant up to +55°C
    Improved dynamics and energy savings with Active Front End (AFE)
    • Active Front End is an option which allows the drive to reduce the total current harmonic distortion (THDI) to less than 4%
    • Altivar Active Front End even works with weak or unstable networks
