PRODUCT DESCRIPTION
The separately excited motor speed controller, Curtis Controller Model 1266R-5251, 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 1266R-5251 is a 36-48-volt model with 275 amperes current limit and utilizes a 3-wire potentiometer. It weighs 3.9 kg and is 229 mm in length, 178 mm in width, and 81 mm in depth. This controller has regenerative braking and programmable parameters as its key features. It also has well-protected components, cutback functions, mobilization control, and WalkAway feature among others
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
Regenerative Braking
Ensures longer operation, reduces motor heating and decreases brush wear
Adjustable and Programmable Parameters
A feature allowing control of brake, speed, and torque and to match motor requirements
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
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
WalkAway braking
The vehicle can only operate at low speeds when off
Reverse Signal Driver
If the vehicle is reversing, it gives a low signal
Short Circuit Protection
Outputs and has integrated protection from coil spike
Buzzer Sound
Reverse: Steady
WalkAway Braking: Intermittent
Status LED
Allows viewing of diagnostics
Plastic Cover
Helps in resisting splashes
Easy Installation
No further alterations are necessary
Ingress Protection (IP) rating that protects the controller from the rugged environment
