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 1313-4431 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.
