electric rickshaw motor controller/48V electric golf cart differential motor

1204M-5203 is the new upgraded version of 1204M-5201 DC series motor controller, with new J5 terminal (reverse signal output / main contactor coil driver), and supporting more throttle types.

Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1204M/05M Manual before making the purchase.

Notice: By default, we will deliver the controller with default setting of 48V / 275A / 0-5kΩ. For better applying the controller to your system, the buyer should confirm with the seller the battery system voltage and the throttle type.

Notice: We supply also the 1204M-5203 controller assemblage with throttle (foot pedal).

Overview

Curtis 1204M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. They are updated versions of the popular 1204 controllers, with the added functionality of being programmable—via the 1313-4401 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.

Curtis 1204M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.
