{tab=Description}

Description:

Curtis Models 1236 and 1238 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.

Application:

Designed primarily for use on medium to large material handling vehicles such as counterbalance or warehouse trucks. The Model 1236 is equally suitable for Light-On-Road passenger vehicles and utility vehicles. The larger Model 1238 is also intended for use on all heavy-duty applications such as Tow Tractors and Airport Ground Support Equipment (GSE).

{tab=Features}

Advanced functionality, compact power

  • High frequency, silent operation across the 0–300Hz stator frequency range.
  • Models available for 350–800A output at 24–96V 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

  • 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.

Meets or complies with relevant US and International Regulations

  • EMC: Designed to the requirements of EN12895
  • Safety: Designed to the requirements of EN1175
  • IP65 Rated per IEC 529
  • UL recognized
  • Regulatory compliance of the complete vehicle system with the controller installed is the responsibility of the vehicle OEM.
