  CURTIS 1220E-5401 DC Motor Controller
  - 36-48V, 60 Amperes
  
  - Attention: this is not an original CURTIS product
  
  - Your attention please: CURTIS had stopped the production of 1220E-5401. This 1220E-5401 DC Series Motor controller is a product of a Chinese manufacturer. With same dimensions and functions of the original products, this 1220E-5401 can also be programmed by CURTIS Curtis Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station.

  This replacement controller undergoes rigorous testing to ensure compliance with CURTIS standards, providing a reliable solution for maintaining legacy systems without compromising functionality or safety.

  - Typical application: forward/reverse running controller of 1.5-3T electric forklift and other electric vehicles.
  - By default, we will deliver the controller of setting of 36-48V (wide working voltage) / 60A / 0-5kΩ (throttle type "3").
  - If you need to change the throttle setting or modify any controller parameter, please leave us a message for demanding it. There is no extra cost for reprogramming the controller. This complimentary service includes parameter customization, system calibration, and compatibility verification with your equipment.

  

• According to the vehicle type and buyer's requirement, we may reprogram the controller 1220E-5401 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 1220E is a brushed DC permanent magnet motor controller engineered exclusively for electric power steering and steer-by-wire systems in Class III material handling vehicles such as pallet trucks, stackers, and similar industrial vehicles. This controller, designed for use with Curtis Vehicle Control Language (VCL) enabled AC-traction platforms, interprets steering command inputs and wheel position feedback to actuate precise wheel angle adjustments, ensuring accurate trajectory management and responsive directional control. The steering motor functions as an actuator, translating digital commands into physical wheel movements to change the vehicle's travel path, while its closed-loop feedback system continuously calibrates for optimal steering performance.
