Overview:
CURTIS 1268 controllers are separately excited motor speed controllers designed for use in a variety of transport vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications include heavy-duty golf carts, personnel transports, burden carriers, and other utility vehicles.
The 1268 controller offers smooth, silent, cost effective control of motor speed and torque. The speed sensor input allows superior closed-loop control for regulating vehicle speed. Unique braking parameters allow simple, intuitive deceleration tuning. A full-bridge field winding control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and regenerative braking power without additional relays or contactors.
Various throttles can be used with the 1268-5403 controller, including 5kΩ 3-wire potentiometers and 0-5V throttles. But 1268-5403 does not support ITS (Inductive Throttle Sensor) type throttle. So 1268-5403 can not be used as a direct replacement of an old 1268-5404, 1268-5411 or other 1268 controller model which works with ITS type throttle. For replacing 1268-5404, 1268-5411 or other ITS 1268-54xx controllers, you need a new throttle which works with 1268-5403, for example:
FT-02YG: ITS throttle but with a regulated 0-5V voltage output
JSQD-DWK-003D: 3-wire 0-5K potentiometer
HXJS-4805: 0-5V voltage throttle
RJSQ-001: 0-5V voltage throttle
ET-126 MCU: CURTIS 0-5V voltage throttle with directional signals (forward / reverse)

1268-5403 controllers are widely applied in different electric vehicles, such as golf carts and utility vehicles.
A speed sensor is required for use with 1268 controller. The speed sensor must be of a pulse type, and must interface to the controller with an open collector NPN transistor output. The most common sensor type will be a Hall effect switch IC, such as the Allegro type UGN3132 or Micro Switch type SS11; these work with an eight-pole (four pulses per revolution) ring magnet attached to the motor shaft. Other pole configurations can be accommodated by programming the Tacho Poles parameter to match the sensor magnet. Linear output sensors such as PM tachogenerators and variable reluctance gear tooth sensors (“magnetic pickups”) are unsuitable.
Notice:
For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1268 Controller Manual (PDF format) before making the purchase.
