CURTIS DC Series Winding Motor Speed Controller

Model: 1221M-6701, 48V / 60V / 72V - 550A

As a new upgraded 1221M series controller, 1221M-6701 provides new functions "reverse signal output / main contactor coil driver" through the 6.35 mm push-on terminal J5. For more details, please read carefully the CURTIS 1204M/05M/09M/21M Manual and CURTIS 1221M-6701 Controller Default Setting Parameter List.

We may provide the complete set of controller assemblage of 1221M-6701. Please contact us for more details.

Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1204M/05M/09M/21M Manual and CURTIS 1221M-6701 Controller Default Setting Parameter List before making the purchase.

Overview:

CURTIS 1221M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1205M controllers are updated versions of the popular 1205 controllers, with the added functionality of being programmable—via the CURTIS Model 1313-4331 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 1221M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.
