Curtis 1234SE-5421 AC Motor Controller 36-48V 450A

PRODUCT DESCRIPTION

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 with a nominal battery supply ranging from 24 to 96 VDC.

The Curtis 1234SE-5421 is a 36/48-volt model with 350 amperes current limit and is the second most compact design among the series. It also uses new state-of-the-art technology that raises 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 this controller. It also allows silent operation, lower heat loss, and manageable torque ripple making it a very efficient model in the industry.

The controller 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.

EXCLUSIVE FEATURES

Features Purpose
Vehicle Control Language The VCL is a programming language that comes in handy as it allows developers to input logic functions that are necessary for the desired application
Field Oriented Control The FOC produces a regulated speed, increases the capability of driving uphill, and enhanced the driving experience
Motor Compatibility Enhanced and easy induction motor pairing
Dual-Drive Functionality Operation is secured and smooth all throughout and helps in reducing the risk of tire wear
CANbus Configuration Communication with other CANbus devices is allowed
Functions as System Controller Can be allocated for contactors, pins of input and output, and drivers.

 

FEATURES

Features Purpose
Upgradable Software The software can be upgraded easily and does not require a technician
Improved Peak Current Rating The feature that enables a more compact design of controller that can operate similarly to the ones in larger designs
Improved Pulse Width Modulation Allows silent and efficient operation by reducing heating losses and lowering torque ripple
FLASH memory and 64 MHz micro Allows additional code to be inputted and speeds up the execution speed of VCL

 

SAFETY FEATURES
