Unlock high-torque performance and precise dynamic speed control with high-power DC Drives, the workhorses of heavy industry. Engineered for applications demanding maximum starting torque and continuous power across full speed ranges, DC drives provide the essential control needed for severe duty cycles. From continuous steel rolling mills to high-capacity mine hoists, extruders, and heavy-duty cranes, these units deliver instant response, smooth speed regulation, and reliable operation under extreme loads

All repairs and refurbished units sold through AFi Systems come with a 2-year warranty!

Free evaluations for your DC drives, with a no-fix no-fee policy!
Any refurbishment includes the replacement of any components likely to degrade over time such as power semiconductors (SCRs/thyristors), gate firing circuit boards, electrolytic capacitors, and electromechanical parts like cooling fans, before being soak tested under full load in one of our dedicated drive bays so we can be confident in our two-year warranty. Our refurbishment services include drives for obsolete products whose legacy fieldbus communications or analog feedback loops prohibit easy retrofitting.
