Curtis Model 1232SE

The SE Series of Curtis controllers are Permanent Magnet AC (PMAC) and AC induction motor controllers. All controllers from the Curtis SE Series control the speed and torque of three-phase AC motors that are usually used in vehicles utilizing hydraulic pump motors and electric traction. The 1232SE has a nominal battery supply ranging from 24 volts to 48 volts, and it is the most compact design among the series.

Compared to other AC controllers from Curtis, the SE models like the 1232SE use new and state-of-the-art technology to raise the peak current rating. Programmable control, a flexible controller for torque and speed, a CANbus that can be configured, twin traction motor control, and a capable controller for the whole system are the exclusive features of AC controllers from Curtis Instruments. The controller also allows silent operation, lower heat loss, and manageable torque ripple making it a very efficient model in the industry.

The Curtis 1232SE controllers can now be purchased here in Cloud Electric, your one-stop shop for all your electric component needs. Cloud Electric is a leading distributor of electronic components in North America. We take pride in our informative product descriptions, pricing, and shipping speed.
