Variable speed drive VSD AK06 Series

Variable Speed Drive (VSD) AK06 series is designed to control and protect the submersible pump, electric submersible pump, and displacement pump units with induction and permanent magnet motors. Triol AK06 VSD solution combines unique technical characteristics, the highest consumer qualities, and excellent reliability. Triol AK06 VSD is represented by 8 lines, each of which was created for a definite segment of the global oil production industry. The lines differ from each other in the cabinet enclosure type and the power device connections at the VSD input. Variable Speed Drives AK06 series provides the optimal solution to a wide range of operational tasks, significantly save the time of engineers, technologists and use algorithms that save resources of oil production companies and contribute to the growth of oil industry. Using products of AK06 series in solving virtually any tasks of ESP technology, oil and oilfield service companies receive the maximum benefit.
