About product

IEEE519 standard

Variable Speed Drive AK06 line PS is another complete solution for the efficient control of installations with both induction and permanent magnet motors, as well as for fulfilling the requirements of IEEE519 standard.

Integrated phase-shifting autotransformer,

PS line drives have an integrated phase-shifting autotransformer, which, in combination with 24-pulse rectifier, provides 5% level of harmonic distortion to the input network in the load range from 25% to 100% in accordance with the IEEE 519 standard, and allows operation at frequency supply deviation ±5%.
