PWM DC motor speed controller 10A 6-55V

This PWM DC motor speed controller handles up to 10 A of continuous current across a 6 V to 55 V input range. It provides clockwise and counter-clockwise direction control with a self-reset protection feature. The integrated digital display shows the duty cycle adjustable from 0 to 100 percent. It suits hobbyists and engineers building variable-speed drives for small DC motors.

Practical limits of the PWM interface

The controller operates only within the stated 6 V to 55 V supply window and cannot be used with higher-voltage systems. Maximum load current is capped at 10 A, so larger motors exceeding this draw are not supported. The single-channel design does not accommodate independent control of multiple motors. Buyers needing isolated channels or higher current capacity must select a different module.
