The Curtis 1204 electronic motor controller is designed to provide a cost-effective solution to control the speed and torque of permanent magnet motors. It is available in multiple models with different specifications and parameters. It offers motor speed control for an extensive range of industrial applications like electric vehicles. It is compatible with 12V, 24V, and 36V permanent magnet DC motors.
Curtis provides a simple wiring procedure in its motor control products so that you can fit it in your product conveniently. You need certain external products along with this electric motor controller. The list is given below

The detailed directions to install the Curtis 1204 electric motor controller are available in the instruction manual with illustrations, relevant figures, and wiring diagrams.
This model has modern features that make it proficient. It is capable of controlling several types of permanent magnet DC motors like brushless DC electric motors.
Adjustable acceleration rate
This feature helps to avoid the irregular and bumpy start. The default acceleration rate circuit ensures the smooth and gentle start of the electric vehicle. It is designed to maintain a maximum increasing rate of acceleration. If the throttle is applied full-on at start-up, the acceleration rate setting determines how quickly the controller output increases. The standard setting is such that the controller will take one second to reach its full power.
The driving range per battery charge of the electric vehicle has increased phenomenally with this feature. In this feature, the Curtis 1204 electric motor controller behaves like a DC transformer. It receives low current high voltage as input and gives high current low voltage as output. Hence, it reduces the current per kilometer drawn from the battery.
High Pedal Disable
A smooth and safe drive of the vehicle is our priority. The HPD function disables the controller if the driver turns on the vehicle with full throttle applied. For the safe start of the vehicle, the motor controller must receive the key switch input before receiving a throttle input.
Open circuit protection
Electric motor controllers shut off the motor if it detects the open circuit in the wiring or in the potentiometer that controls the accelerations of the electric motor.
This feature maintains the maximum limit of the motor current. It protects the dc motor controller and other circuits in the system from receiving high current surges. This reduces the extra stress on batteries and motor during vehicle accelerations and results in more efficiency and life span.
Under voltage protection
This feature is designed to protect the battery. The motor control circuit needs minimum voltage to operate properly. Therefore, the motor controller reduces its output if the battery voltage falls below a certain threshold value.
Thermal protection is added to enhance the safety of the electronic motor control system. The controller has built-in functionality to limit the maximum current to make sure that it doesn’t get too warm.
