{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.
