SKU CH-4RYV-0YV3T

PWM DC motor speed controller with digital display adjusts 0–100 % duty cycle for 6–60 V input up to 30 A

  • Precise speed control with 0–100 % digital adjustment
  • Wide 6 V–60 V input range suits many DC motors
  • High 30 A current capacity handles demanding loads
  • Clear digital display shows duty cycle at a glance

PWM DC Motor Speed Controller 6V–60V

This PWM DC motor speed controller accepts an input range of 6V to 60V and supports a maximum current of 30A. A digital display shows the duty cycle adjustable from 0 to 100 percent. It is suited for hobbyists and technicians who need variable speed control for brushed DC motors in custom projects or test rigs. The module mounts inside an enclosure or chassis where a regulated DC supply is already present.

Build Integration and Requirements

The controller requires a separate DC power source within the stated voltage limits and a motor rated for the supplied current. It frees the builder from designing a discrete PWM circuit and provides immediate visual feedback of the duty setting. No AC mains connection, microcontroller programming or additional driver boards are included. Buyers who need isolated signalling, reverse polarity protection or closed-loop speed regulation should look elsewhere.

Questions about this item

What is the maximum current the controller can handle before it limits output?

The controller is rated for a maximum input of 30A, which is the upper limit for continuous operation.

How much power does the controller itself draw while running a motor all day?

The module uses PWM switching to drive the motor efficiently, keeping its own heat and power draw low during sustained use.
