Product Description

Increased Performance, Improved functionality

Higher performance form, fit and functional replacements for earlier Curtis Model 1236 AC controllers.

 

CE marked as a programmable safety device under

EN ISO 13849-1.
 

Models available from 250-350A output at 24-80V

system voltages.
 

Enhanced 64MHz micro and additional FLASH memory

doubles the available VCL code space and provides

more than twice the VCL execution speed.
 

Six additional VCL-configurable CAN 'mailboxes'

significantly increases CAN master capabilities.
 

Advanced Pulse Width Modulation techniques produce

low motor harmonics, low torque ripple and minimized

heating losses, resulting in high efficiency.

15 kHz	500 VAC	10 kHz	15kHz	300 Hz	linear cutback starts at 85°C; complete cutoff at 95°C	complete cutoff at -40°C

• 

  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 1238E 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 1238E 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 1238SE AC Motor Controller Datasheet before making your purchase.

  As a professional supplier, we possess OEM programs (controller settings) of certain utility vehicles and forklifts. Buyers may contact us and send us the vehicle (forklift) information (manufacturer, model, year of production, etc.), for knowing if we can provide the controller with its OEM program.

  

• According to the vehicle type and buyer's requirement, we may reprogram the controller 1234SE-5421 with CURTIS CURTIS Model 1313-4331 Handheld Programmer or CURTIS 1314 PC programming station. There is no extra cost for reprogramming the controller.

   

  Application Vehicle Example

   

  The Curtis Model 1238E 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 1238E-5621 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.
