Curtis Controllers Model 1203A

Description

The Curtis 1203A motor controller is designed to control permanent magnet motors. It is available in multiple models with different specifications and parameters. Among all Curtis motor controllers, 1203A is the simplest yet efficient device for motor control. It offers motor speed control for numerous mid-ranges to heavy-duty applications. It is compatible with 12V, 24V, and 36V permanent magnet DC motors.

Curtis 1203 DC motor controllerís key features include stress-free installation, smooth acceleration/deceleration, modifiable controlling parameters, and trustworthy protective features. All the power connectors are available on board and its wiring topology is simple with minimum requirements of external components.


Installation

The controller comes with an extremely simple and convenient wiring procedure for its fitting in your product. It has plug-type connectors that allow you to connect and disconnect the motor easily. Battery connectors 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.

  • ON/OFF Switch
  • Forward/Reverse Switch
  • 5KΩ Throttle Potentiometer for speed control

The detailed instructions to install the DC motor controller are available in the manual with illustrations, relevant figures, and wiring diagrams.


Features

Curtis 1203A model has state-of-the-art features that make it proficient. It is capable to control several types of permanent magnet DC motors like brushless DC electric motors.

  • Variable drive, true regenerative, and dynamic braking provide reliable speed control for downhill and deceleration.
  • Power MOSFET technology is highly efficient and doesnít produce extra heat, thus saving the controller from overheating and reducing losses in battery and DC motor.
  • Wig-wag throttle system controls both speed and direction of the DC motor with one potentiometer.
  • Smooth transition from forward to reverse and reverse to forward with the throttle applied during acceleration/deceleration.
  • Adjustable acceleration and braking rates.
  • Programmable top speed with an external potentiometer.


Safety and Protection

It is extremely critical to have the necessary safety functionalities to protect the BLDC motor and its controller. Curtis 1203A model comes with numerous protection features that make it highly reliable.

  • Over-current protection for motor and controller in both drive and braking modes (See compatible motor ratings for further details)
  • Potentiometer fault detection.
  • Battery wires polarity protection doesnít allow the controller to turn ON in case of reverse battery wire connection.
  • Thermal protection prevents the controller from being over-heated. It also has the automatic reset button that turns ON the controller when the temperature is within range.
  • Hi-pedal disable system forces the motor controller to remain neutral if the user power up the devices with throttle applied.
  • Under voltage protection.


Application and Uses:

Curtis 1203A DC motor controller is intended to be installed in various diverse applications. Based on its performance and efficiency, there are certain devices to which it is best suited to install for motor control.

  • Small Electric Vehicles (EVs)
  • Automatic Ground Vehicles (AGVs)
  • Wheel-chairs
  • Scrubbers
  • Sweepers
  • Conveyor belts
  • Robots
  • Power steering
