Variable Drive Speed
|
Yes
|
Allows accurate vehicle control for an improved driving experience
|
|
Power MOSFET
|
Yes
|
Highly efficient, smooth, and noiseless operation
|
|
Throttle: Single-ended
|
Optional
|
Allows full off and full on controls at opposite ends of throttle and a separate component for switch intended for direction control.
|
|
Throttle: Center off (Wig-Wag)
|
Optional
|
Utilizes only one potentiometer controlling direction as well as the speed while its central part turns it off
|
|
Mounting Option: Front
|
Optional
|
Mountable in the front
|
|
Mounting Option: Back
|
Optional
|
Mountable in the back
|
|
Dual Ramp Reversing (Automatic)
|
Yes
|
Allows swift transition in terms of acceleration or deceleration when switching from forward to reverse or vice versa.
|
|
Trimpots (On Board)
|
Yes
|
Allows acceleration and brake adjustment
Allows reduction of speed for reverse function
|
|
Switch or Potentiometer (External Component)
|
Yes
|
Allowing adjustment of top speed by programming it externally
|
|
Neutral Throttle
|
Yes
|
When the vehicle is off and unmanned, it brakes motor
|
|
Electromagnetic Brake
|
Yes
|
Slows down the vehicle by creating resistance once the throttle is on neutral.
|
|
Easy Installation
|
Yes
|
No further alterations and utilizes a two-wire potentiometer
|
Features for Safety and Protection
It is extremely critical to have the necessary safety functionalities to protect the PMDC motor and its controller. The Curtis 1203C model comes with numerous protection features that make it highly reliable:
|
Feature
|
Purpose
|
|
Fault Detection Potentiometer
|
Helps in avoiding runaway conditions
|
|
Housing/Heatsink
|
A protective feature against heat
|
|
Current Limit
|
This feature is helpful for compatibility of the controller with most motors as it prevents over currents for both components
|
|
Polarity Protection
|
Protects the controller by remaining off when the battery wire is reversed due to installation
|
|
High Pedal Disable (HPD)
|
Allows a safe start as it monitors the status of the throttle. If the vehicle is prompted to start with an applied throttle, the HPD disables the operation until the throttle is back in a neutral position
|
|
Temperature Protection
|
Limits the current of an overheated controller and resets it after cooling down.
|
|
Cutback Function (Undervoltage)
|
Allows low battery operation by reducing motor current once the battery is approaching ⅔ of its nominal voltage and prevents the battery from discharging beyond the ⅔ voltage limit
|
APPLICATION AND USES
Curtis 1203C DC motor controllers are intended for various applications. Based on its performance and efficiency, it is best suited to be used for the following application:
Scrubbers
Small Electric Vehicles (EVs)
Automatic Ground Vehicles (AGVs)
Electric Wheelchairs
Power Steering Applications
Sweepers
Conveyor belts
Robotic Applications
INSTALLATION
The controller comes with an extremely simple and convenient wiring procedure for its fitting in your product. It has plug-type connectors that the user can easily connect and disconnect. Its battery connectors also provide a convenient way to install or remove the batteries as per the requirements of the brushless DC electric motor. However, you need the following additional components to complete the motor controller installation process.
Switch for On and Off function
Switch for Forward and Reverse control
Potentiometer for speed control
Detailed instructions to install the Curtis 1203C DC motor controller are available in the manual with illustrations, relevant figures, and wiring diagrams.
