stable performance curtis speed controller 1266R-5351

CURTIS 1266 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 golf carts and small utility vehicles.The 1266 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.
