The Way of the Future

Curtis AC Induction motor speed controllers represent the next level in drive systems for material handling and industrial vehicles, offering lower maintenance, higher performance and greater flexibility. The new Curtis AC controller family delivers an exceptional level of sophistication and adaptability for vehicle designers and end-users. Curtis AC controllers come in compact, fully sealed housings with advanced thermal management. These controllers combine the renowned power and smoothness of Curtis speed controllers with a Programmable Logic Controller to provide rugged strength and unequalled flexibility. From this powerful fusion came the next evolution in motor speed controllers - VCL.
