This will only be possible if you are using a PLC (programmable logic controller) to control the board. If you do, the signal will need to be about In addition, if you're using the included potentiometer, you can use it instead of the PLC, as it connects directly to the same terminals. The board can be used in either direction. In the case of my application, I used it to control a small 12 VDC motor. When the speed is at its highest, the controller puts out about 11 volts. Thus, it does consume a bit of power, like all others As far as I am concerned, it does not With the motor locked, the current draw is just over 4 amps, and this controller was not even warm by the end of the test. As you can imagine, I didn't keep it there very
I'd like to thank you for your attention, since the size of this PCB is 64*59*28mm.
Object-+ Object-- (screw) connections on this board. Motor+ Motor-. A power plus a power minus Disconnect the two wires from the fan and establish whether one of the two is positive using a VOM. Connect the positive wire Wire the other end to the power supply An end point. Motor+ on the controller should be connected to the positive fan connection, and Motor- should be connected to the negative fan connection A negative fan connection is connected to a terminal on the controller. This is the end of your work.
The 15 amp fuse on my unit has been temporarily overloaded and shorted, resulting in a blown fuse. However the unit is still functioning. In one case, I had a unit fail due to excessive heat after running it overloaded for too long.

I ordered one and installed it in my camper to control the speed of my Fantastic Fan. I think the fan runs too fast even at the lowest setting, and there are only 3 settings (H, M, L), so people don't get a wide variety of speeds. Having installed this device, I can now change the speed of my fan at any time, and I can adjust it down to a crawl if I wish, which is great for moving little amounts of air into and Additionally, the fan runs at a much lower speed and is quieter. It's a definite thumbs up from me.
Using this DC voltage regulator has been a pleasure! My project requires it for controlling the speed of a 24V DC gable fan As a whole-house fan, I use an attic fan mounted in the attic. My last 7 years of using a cheap voltage regulator that would not hold the fan speed steady once the voltage was reduced below half was caused by a finicky voltage regulator. My initial thought was that the lack of quality of the old regulator could have contributed to the problem. Thanks for this amazing new one. I had my old cheap one for so long. Although the price is about the same as what I used to pay for the old, inefficient laptop, the performance improves dramatically. Finally I am able to control the speed precisely, even when I'm running at ultra-fast speeds The speed should be low. It is, therefore, in perfect working order. A very high quality product appears to have been made with high quality components and good quality controls. That is the recommendation I would make.
In my case, it didn't work at first. There was a secondary ground wired to the RV fan I had attached to it. In short, this provided a common ground between the power in (which had a chassis connection to ground) and fan out, which rendered the speed controller inoperative. When I removed the chassis ground, and went to a "floating" one, the speed controller worked as it should. Observe my mistake and learn from it.
The two I bought I will be using in There are three different speeds on the dometic fans used in my RY. The original 3 speed switch was bypassed when I installed these. It is now possible for me to control the speeds completely. Slowly to fast and everywhere in between, it goes from crawling to running. It is hard to find a better controller than these. I love how easy it is to install and how well they work. In addition to being controlled electronically, the fans use less power at lower speeds because they do not pass through resistors to control There is a bit of a fit issue, but not an issue that needs to be addressed. If you are going to install them, plan ahead.
Finished my build and am ready to start testing The MOSFET output used in this test is an International Rectifier. Input voltage of 100V at an output current of It would be great if it had a 200V limit so I could just rectify 120VAC, but my application can work with Rectifies to 87VDC from 1 xfmr). The waveform (via O'scope) has a full range of control. Designed with a 1/4 hp PMDC motor so a bandsaw for wood cutting can also be used for cutting.
I was able to regulate the speed of the new larger bath fan in our travel trailer with this product. A new switch for the power was mounted on the wall and a unit was installed into a frame and a pot into the old switch hole for the on/off switch.
Simple, straight-forward design, easy to use, and it will last a long time. The only reason I didn't give it a 5 star rating is that it's made in China, and I couldn't find anything made in the USA which would fit.
It ramps up to full power smoothly from off to full power. In terms of PWMs, I tried two others, but neither worked other than to turn off and turn on the power. Water flow from the pure water tank can be regulated with this device. Even when accidentally soaked with water in the middle of use, this product still works just fine. Buy the one that works in the first place, instead of recommending one that costs less. We are happy with it, and we intend to get a backup just in case, but we'll definitely stick with this one. It does not make any noise or heat up.
