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.

All Curtis AC controllers require application-specific programming prior to integration. For buyers lacking AC motor controller programming expertise, please consult your authorized vehicle/motor dealer and thoroughly review the Curtis 1232SE AC Motor Controller Datasheet before purchasing. This ensures proper configuration for your specific application, including compatibility verification and parameter optimization. Professional programming is recommended to achieve optimal performance and safety compliance.

    Application Vehicle Example

    
    

    The Curtis Model 1232 is intended for use as the traction controller on class 3 material handling "walkies" and other small industrial trucks. It is equally suitable as the pump controller for auxiliary hydraulic functions on larger industrial vehicles.

    Example: controllers 1232SE-5221 are used as driving motor controller of Noblelift pallet truck PT20. For more controller setting details, click here to download the controller parameter list (PDF format), controller program for Noblelift PT20. Attention, this controller program has steering function (working with an EPS controller 1220-2201). Some PT20 pallet trucks have not an EPS controller. The controller program is different for these trucks. For more details, please contact us.
