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.

Regenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heating
Adjustable brake rates, for smooth pedal-release braking
Two user-selectable vehicle operating personalities, with vehicle top speed controlled and limited in each mode
Motor parameters are programmable to match the characteristics of the specific motor being used
Vehicle speed control is enhanced through feedback from a Hall effect speed sensor
Anti-rollback function, providing improved control when throttle is released on hills
Anti-stall function helps prevent motor commutator damage
High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
Complete diagnostics through CURTIS 1313-4431 Handheld Programmer or 1314 PC Programming Station and through the built-in Status LED, for quick and easy testing, diagnostics, and parameter adjustment
WalkAway™ braking feature limits any stopped or key-off rolling to a very low speed
Auxiliary driver can be programmed for either an electromagnetic (EM) brake or a WalkAway™ relay
Coil driver provides adjustable pull-in and holding voltages to WalkAway™ relay or EM brake
Two fault outputs provide diagnostics to remotely mounted displays
Reverse signal driver provides a low signal any time the vehicle is traveling in reverse
Driver outputs are short circuit protected and provide built-in coil spike protection
Brake/Drive Interlock meets ISO stopping distance requirements
Warning buzzer sounds steady in reverse, intermittent during WalkAway™ braking
Splash resistant plastic cover
Meets or exceeds EEC fault detect requirements
