Curtis Controllers Model 1227

The MultiMode Curtis 1227 is a programmable motor speed controller for permanent magnet (PM) motors that is applicable for vehicles with smaller power demands. It is an improved controller version of 1203A, 1208, and 1213 models due to its programmability and enhanced functionality. This is specifically an ABS cover, 24-48 volt model that is primarily designed to be used in small vehicle applications and mobility devices.


The Curtis 1227 offers noiseless and highly efficient motor control operation. A full braking and solid state reversing power is provided by the four quadrant, full bridge power output stage and additional hardware such as contactors and relays are not needed. This controller also has a current limit range of 100 to 250 amperes and a high frequency of 15 kHz.


The Curtis 1227 controllers 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

Full Bridge Power MOSFET

Highly efficient and noiseless operation with a wide range of control

Curtis 1307

Allows parameter programming, diagnostics, and testings

TV Compliance

Ensures that the product follows standards and requirements

MultiMode

User-select feature offering four operating personalities and the top speed of the vehicle is controlled

Speed Limit Input

Once an external speed limit pot is used, the feature allows linear variable speed limiting

Enhanced Linear Acceleration and Deceleration

This feature has a moderate response to operating smoothly

Current Limiting

Improves braking through increasing regenerative braking current limit

Load Compensation

Enhanced loaded and unloaded regulation of speed

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 a neutral position

Key Off Deceleration

Allows smooth stop once it switches off or a fault is detected

Circuitry for Fault Detection

Helps in preventing runaway conditions and monitors components such as the battery, and a contactor, among others

Anti-Forward & Anti-Rollback

A safety function that guarantees no unintentional mobilization will occur

Brake PWM

The holding voltage is reducible through brake driver programming

Reverse Output

It moves the piezo beeper in reverse

Push Switch

Allowing free-wheeling of the vehicle by releasing of brakes

Push-Too-Fast

Speed restriction during manual pushing of the vehicle even without power assistance

Power Saving

Avoids battery drain when not in use

Protection and Compensation Circuit for Temperature

Allows stable current limit and cutback function for during under and over temperature condition

Over and Undervoltage Protection

Protects load from damage

Polarity Protection

Protects the controller by remaining off when the battery wire is reversed due to installation

Momentary Switch Input

Creates a momentary effect to allow end-user input


ACCESSORIES COMPATIBLE WITH CURTIS 1227
