Variable Speed Drive Triol AK06 line CP

Variable Speed Drives AK06 line CP is a complex of unique advanced technologies, which creates the maximum benefit implementing UD line solutions, enabling the minimum level of distortion to the input network due to the built-in passive harmonic filter.

NEMA4, NEMA4X enclosure together with the passive filter is a reliable solution for operation in harsh climatic conditions combined with high demands to the quality of the supply voltage.

The specialized Triol author’s control algorithms provide efficient control of installations with both induction and permanent magnet motors, as well as compliance with the requirements of IEEE519 standard, in the load range from 25% to 120%. VSDs line CP is available in 6 and 12-pulse design, which enables integrating the drive into various power supply systems on the field.
