AC speed controller

Curtis Instruments has added a significant upgrade to its AC motor speed controller family. The new 'E' Series controllers use powerful dualmicroprocessor logic cores that meet all relevant requirements of the EN ISO 13849-1:2009 functional safety standard, and the updated EN 1175-1:1998+A1:2010 industrial truck safety standard.

Model 1232E is said to deliver best-in-class control of AC induction motors and offers high levels of functional safety. It is designed for use as the traction controller on class 3 materials handling 'walkie' vehicles and other small battery-powered industrial trucks. It is equally suitable as the pump controller for auxiliary hydraulic functions on larger industrial vehicles. Improvements over Model 1232 include: Powerful dual-micro logic core ensures full compliance with EN ISO 13849-1; no need for additional safety/supervisory control modules.

Faster 64MHz micro improves motor control, and more than doubles VCL code execution speed Additional FLASH memory and increased CAN Master capabilities with 6more VCL CAN 'mailboxes'.
