Product Details

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 550 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.

Product Details

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.

Easily programmable through the CURTIS Model 1313-4431 Handheld Programmer or 1314 PC Programming Station.
Programmable for either traction or pump applications.
Field upgradeable software.
