Description
The A1000 series will be discontinued as of December 2023. We advise customers who wish to order products currently not in stock to place their orders before the end of November 2023 to ensure it fulfilled.
The A1000 includes next generation product features that provide remarkable technical advantages giving exceptional drive performance and energy saving benefits for induction motor and permanent magnet control. Drives include functional safety features, easy start up and reliable operation. Available for 200v and 400v (up to 480V) three phase supplies with outputs from 0.75kW to 355kW. The AC4A line is designed to run on a 400 V, three phase (3ph) line.
