Product Description
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.
