Variable Speed Drive Triol AK06 line LH

Variable Speed Drive AK06 line LH is a reliable and profitable solution based on the line RD, for applications that require compliance with the requirements of IEEE519 standard in the main operating range of the installation. LH drives provide a minimum level of distortion to the input network due to the built-in passive harmonic filter. The rated output current of the VSDs is from 100 A to 2000 A, the supply voltage is 380 V, 50 Hz and/or 480 V, 60 Hz. Triol provides efficient control of installations both with induction and valve motors with specialized authoring control algorithms.
