Variable Speed Drive Triol AK06 line RD

Variable Speed Drive AK06 line RD is a reliable and cost-effective solution to control submersible units of electric submersible pumps and surface pumping installations for operating conditions from -20 ° C to + 50 ° C with NEMA3R enclosure. A wide range of specialized control algorithms provides an integrated solution for manufacturing tasks. The rated output current of the VSDs varies from 100 A to 3000 A, the supply voltage is 380 V, 50 Hz and/or 480 V 60 Hz (versions with supply voltage up to 550 V are available).
