EC Buying DC Motor Speed Controller
Instructions
- 1. Wiring instructions:
- Motor start and stop indicator: start light on, stop light off
- Digital tube: display the motor adjustment duty cycle, upper and lower limit of the duty cycle, and frequency
- Digital tube: display the motor adjustment duty cycle, upper and lower limits of the duty cycle and frequency
- 2. Digital encoder knob operation:
- In the default interface: (the default display is the duty cycle)
- Short press: switch the motor on and off.
- Press and hold for 10 seconds: enter the setting interface.
- Counterclockwise rotation: the duty cycle decreases.
- Clockwise rotation: increased duty cycle.
- In the setting interface:
- Short press Select the setting parameter, and the setting parameter can be switched between ON-OFF, duty cycle lower limit, duty cycle upper limit a,andd operating frequency. ON-OFF means that the module is normally open or normally closed by default at power-on. The lower limit of the duty cycle is displayed in the form of """" two digits, and the upper limit of the duty cycle is displayed in the form of""H" +twodigitts or 100, the oworkingfrequency is displayed in the form of "F"" twodig ts.
- Long press for 2 seconds: Exit the setting interface.
- Counterclockwise rotation: the corresponding setting parameter decreases.
- Clockwise rotation: the corresponding setting parameter increases.
- 3. STOP port on the back:
- It can be connected to external switch buttons or 3.3V level. Do not use it in complex electromagnetic environments, and there is no relevant protection inside the circuit. (Note that the external switch should use a self-reset button or key, press it once to open, and press it again to close; it cannot realize the function of always closing the output to open, and not closing the output to close).

Have already been using it. Won't give 5 stars until it shows longevity and not a burn out . The cabinet it's mounted in includes a cooling fan so I don't think it'll ever over heat especially when only .9 amps as its only loading at the moment and that won't change unless the motor goes bad maybe? A lot less room needed than for other motor speed controllers which was a plus. Maybe not as much power handling as larger units but not needed for my application. Display is bright and clear and the units control pot is very responsive. The connection terminals are better than others and look good. CAUTION! The wiring sticker on this controller was not matching the actual board designated polarities. Someone was reading upside down. Just peel and turn around. So far a good value if it doesn't crap out for no reason. Don't know any reason it would. One thing that I wish the companies producing these small panel mounts would produce and offer, an angled bezel for tilting them upwards or downward for easily reading when high or low. For my application I don't mind squatting or bending down to read but is not always practical and at my age sometimes painful. As my application of them has me tilting them upwards on the panel face. Top edge of the included bezel is touching the face of panel face and the bottom edge is approximately .250 inches from the face of the panel. This request has no bearing on the unit itself or it's rating from me. Personaly I don't own a three d printer or these would be pretty easy to print. Bottom line is so far so good and nice.

I used this to have repeatable speeds via digital readout when controlling a wind shield wiper motor. It works to control speed from low to high. Would buy again.

Works well. Adjustable frequency, allows true 0% output via rotating the knob. Display is handy. Stays cool at 7 amps, haven’t loaded it any higher.
