Frequently asked questions
How do I connect the motor and power supply?
Connect the DC motor to the motor output terminals and the 6 V to 30 V DC supply to the input terminals, matching polarity as marked on the board. Keep the continuous load within the 5 A rating and do not run at the 8 A maximum for long periods.
What does the digital display show?
It shows the current duty ratio as a percentage from 0% to 100%, so you can see the PWM level applied to the load.
