Features Include:
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.
