The Curtis 24V/36V 500A SX Controller (Model 1244 series) is an advanced, high-performance motor speed controller designed specifically for separately excited (SepEx) DC motors. Operating at 24V to 36V with a high-capacity 500A current rating, this module is widely utilized in heavy-duty material handling equipment, order pickers, stackers, and counterbalance forklifts. Utilizing a full-bridge field and half-bridge armature MOSFET power design, it delivers silent, highly efficient speed and torque management without the need for directional contactors. This specialized model features a CAN-bus communication interface, allowing for real-time telemetry, advanced systems integration, and precise diagnostic mapping.
