1803D Display DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM).
The input power range is DC 6V-28V .
Use a 2A resettable fuse to protect the controller.
Potentiometer cable length 0.4".
The display range of 2-digit LED display is "00"-"99". (For example, displayed "56", it means that the PWM output duty cycle is 56%. )
Before you attempting to wire the controller, make sure power is off.
WARNING: DO NOT REVERSE POSTIVE AND NEGATIVE POWER LOADS.THIS WILL DAMAGE THE CONTROLLER.
TO CHANGE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF MOTOR.
1. Connect wires refer to the "wiring diagram" (NO.6 picture).
2. Turn on the power, and adjust the potentiometer.
3. The LED display displays the PWM output duty cycle.
