Review: Works well for controlling cooling fans and other motors. - I bought 2 of these to control 2 radiator fans that I used to build a cooling system in my SxS. Everything works very good and being able to control the fan speed is awesome. You need to know how to wire electrical components and build them to withstand the conditions they’ll be used in. In the least, understand instructions so you can effectively build your electrical system.
Review: Works Perfectly for my use case - I already reviewed this but here it is again. My use case was to provide variable speed control to a 12v Kamado Joe smoker air blower fan motor. I selected this PWM unit because the exterior design would look almost "factory" on my blower motor housing. The terminal block is well labeled and robust. The dial is a digitizer which makes it a lot more flexible. When I first tested this set up, the controller was not linear, meaning the fan didn't turn on until the dial was set above 20% power. After that, the motor speed ramped up to 100% at a setting of 50% on the digitizer. That would have worked but i wanted a very fine linear control as air flow on a KJ is critical to stable temps. I corrected this by inserting a 4.7 ohm 25-watt resistor on the + fan lead. It now works perfectly. The motor starts at 1% and ramps up to full speed at 100% dialed power setting. My motor only draws 1.5 amps so the 12A capacity of this unit indicates major over engineering so it should last a long time.

## Features

- ♥Product parameters: 1. Working voltage: DC9V~60V, input anti-reverse connection protection 2. Rated current: 12A, maximum current 20A 3. Maximum power: 500W 4. Operating frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency 20KHz, accuracy about 1% 5. Duty cycle: 0-100%, 1% step 6. Product size: 79mm*43mm*26mm Installation hole size: 39.3mm*76.5mm 7. Product weight: 43g (bare weight), 65.5g (with packaging) 8. All settable parameters are stored when power is off.
- ♥ Wiring Instructions: ① Motor start and stop indicator: start light on, stop light off ②Digital tube: display the duty cycle of motor adjustment, upper and lower limit of duty cycle and frequency ③Digital tube: Display the motor adjustment duty cycle, upper and lower limit of duty cycle and frequency" ④It can be connected to switch signal or 3.3V level signal to control the start and stop of the motor ⑤ Motor output positive and negative poles Power input positive and negative
- ♥ Digital encoder knob operation: ①In 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.
- ♥②Setting interface: Short press: select the setting parameter, the setting parameter can be switched between ON-OFF, duty cycle lower limit, duty cycle upper limit, and operating frequency. ON-OFF is the default module power-on normally open or normally closed, the lower limit of the duty cycle is displayed in the form of "L" + two digits, and the upper limit of the duty cycle is displayed in the form of "H" + two digits or "100", the operating frequency Displayed in the form of "+two digits".
- ♥STOP port on the back: It can be connected to external switch buttons or a 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 turn it on, and press it again to turn it off; it cannot realize the function of always closing the output to open, and not closing the output to close).
