This product is a digital encoder that comes with a start stop button and can be controlled by an external switch to meet various control needs. The motor has a soft start function, and the current slowly increases when starting the motor without any surge current, effectively protecting the motor and extending its service life. The digital encoder knob is adjustable The motor speed is adjusted with higher accuracy and better consistency than ordinary potentiometers. Working voltage: DC5V~30V, input anti reverse connection protection Rated current: 5A Maximum current 15A Maximum power: 150W
Working frequency: 1KHz~99KHz adjustable, 1KHz step by step, default frequency 20KHz, accuracy of about 1%
Duty cycle: 0-100%, 1% step
Product size: 79mm * 43mm * 26mm
Parameter power-off saving
Instructions for use:
1. In the default interface: (The default display is the duty cycle)
Short press - switch motor start stop
Counterclockwise rotation - duty cycle decreases
Clockwise rotation - duty cycle increases
Long press - enter the settings interface
2. In the settings interface:
Short press to select the setting parameters one by one, and switch between the lower duty cycle, upper duty cycle, and operating frequency. The lower limit of the duty cycle is displayed in the form of "L"+two digits, the duty cycle, the upper limit is displayed in the form of "H"+two digits or "100", and the operating frequency is displayed in the form of "F"+two digits.
Counterclockwise rotation - corresponding setting parameters decrease
Clockwise rotation - corresponding increase in setting parameters
Long press - exit the settings interface
3. Back STOP port
External switch buttons or 3.3V level can be connected, and once the button is closed or the 3.3V level is pulled down, the start/stop status of the motor can be switched.

So far I've only tested them to power 12-volt fans, and they are impressive to look at! Hope they hold up, they seem to be well made and well thought out.

I love gadgets, especially in my Jeep. Besides the normal runs of lights and accessories I have a big audio system in my vehicle. My audio system, given the limited space to install things, tends to run hot, especially in the summer. I was looking for a way of fixing this and so I installed a big air-duct/bilge fan to circulate air around my amplifiers. At first I had an on-off switch, but at full tilt this fan is NOISY, and given that its purpose is to allow me to enjoy my music I wanted a way of limiting that noise, so I decided to install a DC switch. I tried three from Amazon, two of which malfunctioned and the third, which worked, just looking terrible for the installation. When I saw these I had to jump.These are really nice controllers! The other three I tried were aesthetically much less pleasing, just metal cages with a rotary knob. You couldn't really tell what the speed setting was, and, unless you were wanting to detach the knob and install it through a panel, were bulky and made good mounting difficult. These switches actually look good on a panel. The LCD indicator is bright and lets you know exactly what your fan speed is. The knob is even an on-off switch; you just push in on the knob and you can power it on and off. It stays lit up when you've turned it off, so I still have it on a separate toggle switch, but I love the feature.I have one of these installed on my dash, and it's about to be joined by the other when I install my second blower fan.Overall I'm really excited about how well these turned out in my project. I highly recommend!Note: the set screw plugs on the bottom are a little narrow. If you're having trouble getting the wires in and keeping them from touching I suggest getting ferrules with a ferrule crimper, it made it incredibly easy to set mine up and the installation looks clean.Note 2: if you look at my picture it appears the face is rippled. It's not, that's a piece of tint film I used to lower the brightness for night driving.

Husband is planning to use these controllers on the shake table he is building for his gold hunting adventures. He needed something to control the vibrating DC motor, and these fit the bill. The controllers are well made, and Husband likes that they can be installed into a panel for a control board. Preliminary testing has proven positive.
