It's a PWM speed controller which enables you to control the speed of those DC brush motors smoothly. It's ideal for applications like car motors, DC heater, bulb etc. providing nice adjustment of motor speed.

Wide voltage range, 10-50V, 40A, max. 2000W for motor speed control & HOO.
Apply PWM Modulation system to adjust motor speed from 5-100% .
Stable in working, high efficiency and low noise.
Field-effect tube, drive IC, 70μm copper sheet PCB for higher efficiency of PWM wave output.
Potentiometer for speed adjustment, protective case creates better durability.

Specific Power Control:
12V: 480W; 24V: 960W; 36V: 1440W;40V: 1600W; 50V: 2000W

PWM Working Principle:
BY changing the duty ratio of square wave(output) to adjust average current power from 0-100% on load, thus to change the motor speed or light brightness.

Main Applications:
1.Universal DC brush motor speed control.
2.Control motor speed of cars(eg. car cooling fan motor, car fan motor, car windshield wiper motor, air condition fan motor)
3.Adjust speed of the conveyor of product lines, tube exhaust fan, treadmill, electric fan.
4.Adjust temperature of DC heater, brightness of common DC bulb.

    Actually, I write no reviews ... but this is absolutely necessary! The amp is extremely powerful, it operates a 10 "subwoofer and two small 4" high / midrange speakers at my desk. You can adjust the volume for the bass precisely. The built-in crossover separates clean, but hardly allows for setting options. But enough to properly tune the speakers to each other. Of course, it's not for real high fidelity speakers in a listening room. Sure ... But it sounds just as good as every fifteen fifteen sub approx 500 € amplifier. (Subjective assessment) When I make so loud that my neighbors know which song is playing, the amp uses 3 watts. The production quality is very good. No solder joints are bad and there is nothing to improve. I am completely enthusiastic about the part and ordered one more directly, then for a mobile box.

    Attached to a power supply unit for PC and to a motor recovered from a child's machine, it works very well. Almost perfect housing in its little box. Highly recommended.

    For low prices, part is the hammer. The sound quality is very good. If the volume is slightly higher, you already know that the board is hot, but you can still touch it without any problem. I am operating a 2x30 watt car speaker in the module, but so far there is no subwoofer, maybe later. Delete purchase suggestions. Very suitable for fans.

    For the price, the part is a clear recommendation. (now have 4 of them in operation!) The sound quality is above reproach. That which costs the 5th star, the volume can not be regulated separately for bass and overall.

    This product is excellent for me for price quality, but not only because it was applied with a 12V DC 40A motor and does its job. I advise. For me the only flaw is the potentiometer cables too short. We will have to evaluate it over time.

    Have used the PWM module so far only for the test of my construction, it is driven with a windshield wiper motor to which a stirrer hangs. Has worked flawlessly, so far I am very satisfied. A star deduction, however, I have to give because the PWM frequency has chosen the manufacturer is quite annoying, high frequency in the clearly audible range. A star more if the frequency would be higher, but for the function itself, the device is great. Very nice synonymous find that the module only dry when you turned a few degrees on the pogo and thus it has a switch.
