The separately excited motor speed controller, Curtis Controller Model 1266A-5201, operates at a high frequency of 16 kHz, making them a noiseless and cost-efficient choice as they allow smooth control of brake, torque, and speed. It is designed to suit various transport vehicles ranging from golf carts to light vehicles.
The Curtis 1266A-5201 is a 36-48-volt model with 275 amperes current limit and utilizes a 3-wire potentiometer. It weighs 3.9 kg and is 198 mm in length, 114 mm in width, and 68 mm in depth. The controller has a wide variation of throttle type options and allows the high pedal disable (HPD) feature. It also has well-protected components, cutback functions, fault protection, and plug braking diode among other features.
The controller can now be purchased here in Cloud Electric, your one-stop shop for all your electric component needs. Cloud Electric is a leading distributor of electronic components in North America. We take pride in our informative product descriptions, pricing, and shipping speed.

FEATURES
|
Feature
|
Purpose
|
|
Power MOSFET
|
Highly efficient and noiseless operation
|
|
Adjustable Parameters
|
A feature allowing control of brake, speed, and torque
|
|
Full-Bridge Field and Half-Bridge Armature
|
A feature that allows near zero speed due to regenerative braking
|
|
MultiMode input
|
The top speed of the vehicle is controlled and with applied limits along with 2 operating personalities
|
|
Hall Effect Speed Sensor
|
The speed control is improved due to this feature
|
|
Overspeed braking
|
Inhibits overspeeding when going through downward slopes
|
|
Anti-rollback function
|
When driving uphill, the vehicle is inhibited to roll backward
|
|
Anti-stall function
|
Protects motor commutator from harm
|
|
High Pedal Disable
|
Allows a safe start by monitoring the status of the throttle. If the vehicle is started with an applied throttle, this feature disables it from operating until the throttle is returned to the neutral position
|
|
Static Return to Off
|
Allows a safe start by requiring the forward and reverse selector to be returned to a neutral position before allowing an output
|
|
Electromagnetic Braking
|
Slows down the vehicle by creating resistance once the throttle is on neutral.
|
|
Main Contactor Automatic Shutdown
|
Once the pedal is released and prompted to stop, the vehicle shuts down
|
|
Current Boost
|
A programmable feature that helps assist startup
|
|
Short Circuit Protection
|
Outputs and has integrated protection from coil spike
|
|
Fault Detection
|
Checks internal components for faulty processes through a programmer
|
|
System Monitoring
|
Monitors battery, throttle, and other components through a programmer
|
|
Easy Installation
|
No further alterations are necessary
|
|
IP5X
|
Ingress Protection (IP) rating that protects the controller from the rugged environment
|
ACCESSORIES COMPATIBLE WITH CURTIS 1266
Curtis 1314 - a PC programming station
Curtis 1311 - a programmer that assists in parameter control and system diagnostics.
