## Description

PWM controller for brushed DC motors, ideal for smooth speed control and direction change. Operates at 10-55V and supports up to 40A continuously, providing power up to 2000W. Includes potentiometer for 0-100% speed, 3-position switch for direction and stop, plus external display for clear display.
Speed and direction controller for DC motors with a voltage between 10 and 55V and a maximum power of 2000W, with display, potentiometer for speed regulation and 3-position switch for the direction of rotation (the middle position is off).
The module uses the PWM method to change the motor speed.
The display on this model is external. It can be inserted directly on the PCB after removing the pins or used as such, with wires, if it is desired to position it in a position further away from the PCB.
Important: during transport, the display wires can disconnect . These wires can be easily tangled, which leads to the damage of the display/module. Carefully check the correct order of these wires. As a help, fix the display according to the picture below, with the points down, and lead the wires one by one from the board to the display.
