About this item

  • 1. PWM speed controller adopts PWM control technology to realize temperature control and speed regulation. The fan speed can be controlled according to the ambient temperature. When the ambient temperature is lower than the set starting temperature, the governor controls the fan to stop running.
  • 2. Fan speed controller, small size, high performance, saving operation space. Fan Temperature Controller small size: 2.20x1.38x0.79inch (LxWxH), M3 mounting hole. Can control various 12V/24V DC 2-wire/3-wire/4-wire fans or motors. Maximum drive current 4A. [3-wire/4-wire fans only need to connect the fan's power cord to the controller]
  • 3. Dual working mode optional, fixed temperature mode or adjustable temperature mode. Fixed mode: The starting temperature of the governor becomes 30℃ (86°F), 30 to 50 degrees fan speed linear increase, 50°C(122°F) above the fan at full speed; Adjustable mode: Start-up temperature range: 10-50°C, full speed range of 30-70°C (Full-speed temperature=Start temperature +20°C).
  • 4. Fan speed control module is equipped with a high-precision temperature sensor with a cable length of 30cm/11.8inch and comes with a mounting buckle. It can be used to measure the temperature of air, liquid and solid surface. The temperature measurement range is -20~110℃. The temperature measurement accuracy is ±1℃.
  • 5. Notice: The voltage of the DC power supply used must be the same as the voltage of the fan, and the current of the power supply must be greater than the total current of the fan. The speed governor has a hysteresis circuit. The start temperature and the stop temperature of the fan are set by the difference of 2°C.


Product Description

1

Package Included: 1x 4A Speed Controller with Sensor

This speed governor uses PWM control technology to realize temperature control and speed regulation. The speed governor controls the fan speed according to the ambient temperature. The higher the temperature, the faster the speed. When the ambient temperature is lower than the set starting temperature, the governor controls the fan to stop running.

Features:

1. Dual working mode (Fixed temperature range + Adjustable temperature), supports various DC24V/12V fan access.

2. With power supply reverse protection function, it can protect the controller and fan from damage when the negative pole is reversed.

3. Using industrial-grade solutions, excellent performance, maximum drive current 2A/4A.

4. Dynamic LED indicator, more intuitive and true understanding of the working status of the controller.

5. The devices are basically SMD packaging, with high craftsmanship, small size, and space saving.

6. The temperature sensor is equipped with connecting wires and mounting holes, which can detect the temperature of air and liquid.

7. Product size: 2.20x1.38x0.79inch (LxWxH), M3 mounting holes.

Notice:

1. The voltage of the DC power supply used must be the same as the voltage of the fan, and the current of the power supply must be greater than the total current of the fan.

2. The speed governor has a hysteresis circuit. The start temperature and the stop temperature of the fan are set by the difference of 2°C. For example, the set start temperature is 30°C. When the temperature is lower than 28°C, the fan will stop. After the fan stops, wait for the temperature to rise. The fan will not start until 30 degrees or more.

3. When multiple fans need to be connected, connect them in parallel directly to the fan's wiring port, but ensure that the total current of the fans does not exceed the rated current of the governor.

Use it in an outdoor pelican case with Raspberry Pi and power supply running FlightAware. Turns fans off in evening when cool and on when the day heats up.

This runs an in and out flow cooling fan system on a DIY solar generator built into a Ryobi link tool box cooling the charge controller and inverter. It's been protecting $200 of equipment perfectly for nearly two years, outside in the Texas heat.

I rated this product 5 stars because there is no other product I can find like it - that has a variable output depending on probe temperature. The product works as it is supposed to. If I were to count off stars, it would be for these reasons: (1) The mode selector switch has no labels. (2) There are no instructions) (3) The adjustment potentiometer is very difficult to adjust. Otherwise, I have no complaints.

The switch needs to be set correctly. Once it was I used a screwdriver to set the starting temperature and a thermometer gun. Now this amp is silent for a while, then I hear the fan come on low, and as the temperature rises the fan speeds up. At some point this reacts as a temperature regulator of sorts. This works very well.

speed controller that works as advertised

It does do this test spin up of the drives occasionally. I haven't exactly figured it out, I wish if it turned the fans on they would stay on for a minute instead of just a few seconds. I haven't noticed it now that its cooler weather. I have two high speed fans on this and I wish there was a way to control the fan speed since its just off/on with no speed control.

I will be using this to ventilate a space under a bed in my RV where I have a 3000W Victron inverter/charger. The equipment in this space can generate a lot of heat when in heavy use, so I bought this to control powered ventilation of the space. In my testing, it kicks on right at 30C with about 3.5V to the fan, which I am supplying 13.5V. As I increased the tempurature to the probe, the voltage scaled in a linear fashion until the full 13.5V was being provided to the fan at just shy of 50C. This is perfect for my use, as it allows the fan to start ventilating quietly, and the fan only gets loud-ish when it's really hot and I need to move a lot more air. With two fan outputs, I can run two fans from this one controller. Super happy with the purchase for my use case. I am using the Fixed mode setting, which is the default.
