Product Description

 1266 Controller Manual

1266 Controller Datasheet 

1266A-5201 controller default setting parameter list

1313-4331 Handheld Programmer

- PWM operating frequency: 16 kHz
- Electrical isolation to heatsink (min.):500 VAC
- KSI input voltage (minimum): 16.8 V

When you buy a controller 1266A-5201 with convert kit,we will reprogram the controller for obtaining the same configuration of a 1510A-5251.Please consult cart/motor dealer and read carefully the 1266 Controller Manual and 1266 Controller Datasheet before making the purchase.

By default,we will deliver the controller with default setting of 48V/275A.Various throttles can be used with the 1266A-5201 controller,including 5kΩ 3-wire potentiometers,0–5V throttles,and electronic throttles.For more controller parameter details,please take a look at the 1266A-5201 controller default setting parameter list.

For activating the 1313-4331 Handheld Programmer or 1314 PC Programming Station,J1-8 and J1-16 terminals should be connected to "B+" of DC power source (minimum 16.8V,maximum vehicle system voltage);"B-" busbar should be connected to "B-"of DC power source (minimum 16.8V,maximum vehicle system voltage).

Notice: We supply also the 1266A-5201 controller assemblage with throttle (foot pedal).

- 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.
- With a transfer connector (convert kit),the 1266A-5201 can easily replace the 1510A-5251 SX(Seperately Excited or SepEx) motor speed controller (Part Number 102806201,CURTIS Model Number 1510A-5251).The two controllers have the same installation dimension.
