Description:
The Curtis Model 1234 provides advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties. It offers vehicle developers a highly cost-effective combination of power, performance and functionality.
Application:
Designed primarily for material handling vehicles such as warehouse trucks and small counterbalance forklifts. The Model 1234 is equally suitable for utility vehicles, golf cars and Light-On-Road applications.
{tab=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
- 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.
