Curtis Speed Controller - AC Motor - 24-36v 400A 1236-4401

{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).

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.
