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.

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
