DC motor speed controller 9-60V DC, 60A

The PWM controller is designed for controlling the speed of a DC motor in the supply range of 9 to 60 V. The module uses continuous regulation in the range of 0 to 100% and is equipped with a digital display to display the set regulation level. The assembly includes a potentiometer with a control knob and a separate rocker switch. The design with power elements on the board and screw terminals is suitable for installation in equipment and technical applications with DC motors.
