The 'E' difference: a significant enhancement to the CURTIS AC family, The 'E' models utilize a powerful dual-microprocessor logic architecture to provide improved performance and surpass the requirements of the latest international functional safety standards. CURTIS controllers 1232E provide advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties. They offer vehicle developers a highly cost-effective combination of power, performance and functionality. Designed primarily for use on small to medium material handling vehicles such as counterbalance or warehouse trucks. The Model 1232E is equally suitable for industrial utility vehicles.
It is supposed that the CURTIS AC Controller need to be programmed before applying to a specific application. For the buyer without AC MOTOR CONTROLLER PROGRAMMING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1232SE AC Motor Controller Datasheet before making your purchase.
As a professional supplier, we possess OEM programs (controller settings) of certain utility vehicles and forklifts.
