About product

Compliance with IEEE519

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.

Built-in input harmonic filter

LH drives provide a minimum level of distortion to the input network due to the built-in input 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.
