We have several type of DC motor PWM controllers!
Simple forward or reversible version. up to 300A and 200V with programmable USART and other useful functions and more...




Very important: 

Because of some missunderstandings for those customers who does not need the programing registers and the serial communication they dont have to learn and deal with the programing! 
The controller is fully  working  without doing any programing. In the datasheet you will find information about the programing but telling you again that is not important to you if  you just want to use a simple potentiometer or throttle controlling your motor. You just need to choose the controll mode with the red DIP switch 1-2 on the board. The controller's registers are optional for those users who need this function for their application.

^^^Donload the datasheet with this link^^^

^^Here you can find a few possible heatsink for the controller^^

This is a very compact and easy to use high efficiency PWM speed controller for any brushed motor with RS232 communication for your developement or project. You can use it with siple potentiometer or for more adjustable functions controll with simple USART read/write commands using Arduino/PLC/computer or any other MCU.


Use it for trolley, outboard, electric bicycle, go-cart, boat and any other industrial application.

With a few easy step it needs to place to a heatsink or an aluminium plate! 

Just connect your battery and your motor to the M5 screw terminals set the maximum current with the small blue trimmer potentiometer on the board and you are ready.


Advantages against other motor controllers:
  • 5 operation mode: normal potentiometer/magnetic hall throttle (with 0.5-4,5V output)/direct PWM input (0-95%)/ RC PWM receiver input 1,5ms +/-1ms and TTL RS232 communication with much more adjustable parameter compared to the potentiometer settings.
  • Addressable serial communication (RS232) it is possible to connect multiple controllers on one RX/TX line and control them as you wish with simple read/write commands. For the communication protocoll please read the datasheet.
  • 2 quadrant operation (drive CW and regenerative brake CW)
  • Connection with high current M5 screws.
  • 20kHz switching frequency
  • Duty cycle: 0-95%
  • Universal 0-5V speed controller input. You don't have to use the potentiometer to controll the speed. You can use PLC 
    output or any analoge signal or PWM signap from uPC or RC receiver PWM signal.
  • Regenerative braking (you can brake the motor and get back all the kinetic energy into the battery)
    For the highest safety the regenerative braking never     replaces the normal brake!
  • Adjustable ramp speed (acceleration limit). 0-20sec.
  • Normal current limit is adjustable between 0-50A
  • Peak current 70A.
  • Universal supply voltage between 10-50V DC.  (if you need higher voltage 80V with lower current please contact or leave a note with the order)
  • Dimensions: 61 x 70 x 25 mm
  • 80g

Adjustable and readable settings throught RS232:
  • Check the Register MAP picure in the item gallery 

Why choose this controller?

On the ebay there is many type of controller the most piece is a chinese simple and cheap controller. They are great until you put a large load to they output. 
-That controllers don't have supply filtering what is very important! Without it the most of the chinese controller regularly burning down. 
-They haven't got proper flyback diode against the motor inductive current! 
-The most of them don't have any current limit function which is very important by a motor.

This controller is a current limited speed controller for any brushed DC motor with great LOW ESR capacitor supply filtering and a syncronous flyback diode!

Attention!

The best pactice to place this controller if you place it into vertical position. This can gain the natural air convection! 
 
How can you controll the motor speed with this controller?

With the current limit potentiometer you can very fine adjust the current what the motor can maximum consumes.
For example, you have 500W 24V DC motor. Your motor nominal current is 20A. Than you adjust the current limit to 25-30A.
After them your motor and PWM driver is fully protected against the burning down and over load.  The controller measure the temperature of heatsink. If that exceed the maximum than the controller shutting down.
You can easily control the motor speed between 0-95% with the motor speed controller potentiometer which is connected to the potentiometer terminal.
You can use as long potentiometer cable as you want. So you don't have to mount the PWM and the potentiometer juxtaposed.
