  • Important information:

It is necessary that the Curtis AC Controller is programmed before applying to a specific application. For a customer without AC Motor Controller Programming knowledge or experience, please consult your motor dealer and carefully read the Curtis 1234 AC Motor Controller Manual before making your purchase.

Typical Application: Chery FB15 1.5T Electric Counterbalanced Forklift Truck controller.

Our knowledgeable technicians possess OEM programs (controller settings) of certain utility vehicles and forklifts. Customers may contact us and send us the vehicle or forklift information (manufacturer, model and year of production), to see see if we can provide the controller with its OEM program.

This 1234-5271 can also be programmed by Curtis Model 1313-4401 Handheld Programmer or Curtis 1314 PC programming station. There is no extra cost for reprogramming the controller.

Product Overview

Curtis 1234 AC induction motor controllers deliver smooth power unlike any previous vehicle control system. They provide unprecedented flexibility and power through inclusion of a field-programmable logic controller embedded in a state-of-the-art motor controller.

The embedded logic controller runs a fully functional field-oriented AC motor control operating system (OS) that can be user-tailored via parameter modification. The OS also contains logic to execute OEM developed software, called VCL, that can be used to enhance the controller capabilities beyond the basics.

VCL (Vehicle Control Language) is an innovative software programming language developed by Curtis. Many electric vehicle functions are uniquely built into the VCL code, and additional functions can be OEM-controlled using VCL code. VCL opens new avenues of customization, product differentiation, and responsiveness to the market.

The CAN bus communications included in the 1234, as well as in many other Curtis products, allow these AC induction motor controllers to be part of an efficient distributed system. Inputs and outputs can be optimally shared throughout the system, minimizing wiring and creating integrated functions that often reduce the cost of the system. Curtis 1234 controllers are the ideal solution for traction, hoist, dual drive, and other motor drive and vehicle control needs.

The 1234 controllers are fully programmable through the Curtis Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. The programmer provides diagnostic and test capability in addition to configuration flexibility.

Features

Advanced functionality, compact power

  • High frequency, silent operation across the 0-300Hz stator frequency range.
  • Models available for 200-350A output at 24-48V system voltages. These are true 2 minute RMS ratings, not short duration ‘boost’ ratings.
  • Powerful operating system allows parallel processing of vehicle control tasks, motor control tasks and user configurable programmable logic.
  • Advanced Pulse Width Modulation techniques produce low motor harmonics, low torque ripple and minimized heating losses, resulting in high efficiency.

Unmatched Flexibility

  • Easily programmable through the Curtis Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
  • Programmable for either traction or pump applications.
  • Field upgradeable software.
  • Integrated Battery state-of-charge algorithm and hour meter.
  • Multi-ModeTM provides user-selectable vehicle operating profiles.
  • Fully-featured generic software and VCL for typical Warehouse Truck applications is included.
  • Comprehensive programming options and VCL allow other applications to be easily supported.
  • Curtis hand-held or PC Windows programming tools provide easy programming and powerful system diagnostic tools.
  • Integrated status LED provides instant diagnostic indication.

Robust Safety and Reliability

  • Insulated Metal Substrate power base provides superior heat transfer for increased reliability.
  • Fail-Safe power component design.
  • Redundant hardware watchdog timers.
  • Reverse polarity protection on battery connections.
  • Short circuit protection on all output drivers.
  • Thermal cutback, warning, and automatic shutdown provide protection to motor and controller.
  • Rugged sealed housing and connectors meet IP65 environmental sealing standards for use in harsh environments.

This is a replacement controller with the same function, structure and dimensions as the original part from the OEM.

Please contact us for compatibility. Our forklift technicians can help you find the right part for your needs.
