Features Include:
Increased Performance, Improved functionality
Higher performance form, fit and functional replacements for earlier CURTIS Model 1238 AC controllers.
CE marked as a programmable safety device under EN ISO 13849-1.
Models available for 450 output at 48-84V system voltages. These are true 2 minute RMS ratings, not short duration 'boost' ratings.
Enhanced 64MHz micro and additional FLASH memory doubles the available VCL code space and provides more than twice the VCL execution speed.
Six additional VCL-configurable CAN "mailboxes" significantly increases CAN master capabilities.
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.
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
Dual Microprocessor architecture cross-checks critical circuits, logic, and software functions to ensure the highest possible functional safety performance level is achieved.
Insulated Metal Substrate power base provides superior heat transfer for increased reliability.
Fail-Safe power component design.
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.
