Note:

DC motor speed regulator DC power supply, do not be directly connected to household 220V AC.

Please allow 1-3mm differs due to manual measurement.

Connect a voltage of 1.8V-15V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse in line with the positive supply in order to protect the circuit from any possible short circuits.

You can now control the speed of the motor through potentiometer. Important Notes： An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. The controller is safe with a self-recovery fuse 2A. It will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes

User questions & answers

Question:	can this be used on a minn kota EDGE 45lb.thrust 5 speed trolling motor
Answer:	If it's between 7-70v, below 30amps, and a brushed motor, yes. Amp draw is going to be the issue, some trolling motors can draw over 30amps which would blow the fuse and just swapping to a higher rated fuse is asking for trouble.
Question:	In the wiring diagram the fuse lines wire is black, but the actual wire is red. That's confusing, where will the fuse line wire go? M+ or M
Answer:	I used this speed control in my son's Power wheels. What I did was places the fuse line in Input P+ (P+ and P- are for the wires from the power source, e.g. the battery . Dont concern your self with the fuse line wire color. M+ and M- are the output contacts the wires coming from or going to the moter are connected there. Hope this helps. You can also look up YouTube videos to give you a visual of how to connect the speed control.
Question:	Why does the internal fuse keep popping with a 20V 5A dewalt battery swap in a powerwheels car
Answer:	The DEWALT battery is most likely a 5AH which rating of length of power but a DEWALT battery will actually pop a 30A fuse on initial power surge. I just recently used one of these on my daughters power wheels and I ended up putting a 40A fusel in and haven’t had any issues so far
Question:	It worked at first, now it won’t limit speed. Just full speed. Any idea what’s wrong
Answer:	Unfortunately the one I purchased stopped working after an hour.

User questions & answers

Question:	Before I return it: I'm using it to run a 10,000 rpm cooling fan. There does not seem a "middle ground" - only on and off
Answer:	Absolutely none; it is the best smoke alarm I have ever bought. I placed it in a 4-foot hallway between the kitchen and foyer.
Question:	Can it be powered by an adapter 12V 5A
Answer:	This is only a photo detector sensor. I bought one thinking it had both given their "sees both fast and slow burning" but discovered otherwise and sent it back. I ended up replacing it with a First Alert SA320CN (dual sensor) which rates high by consumer reports and have had no issues.
Question:	What is the PWM frequency and is the frequency adjustable
Answer:	The red wire pictured is to interconnect the alarms throughout the house. If you only have two wires (probably white-neutral and black-hot) it is not interconnected. So if you wanted to upgrade to an interconnected for safety or code reasons you may want to consider ones that are wirelessly interconnected, although I don't have any personal experience if they are problematic. Or you could simply go with a stand alone plug in. If you read my review, I would highly recommend against the Kiddie p12040 regardless.
Question:	Can you connect 2 motors (as long as you are under 3A), or will there be a problem? Please answer if you are the manufacturer or know for sure
Answer:	I cannot post a photo, but if you are replacing a Kidde with a kidde, the harness hasn't changed.

User questions & answers

Question:	is this the only thing i need to get to reduce the speed of a 24vdc motor ? It uses about 3 amps at full speed
Answer:	Ionization type. I actually looked at at manual to be certain.
Question:	Can it be used on a 12v / 24 lbs thrust trolling for a kayak
Answer:	All smoke detectors begin to degrade after five or six years and should generally be replaced in the range of six to eight years--even if you don't get the malfunction or end-of-life signal first. You should never keep them longer than ten years--period. Even if they technically still "work," they aren't nearly as effective as they should be. Why take chances with something so important?
Question:	Will it handle 20 or 24 volts in and reduce to 12 volts out? Not really stated. Do i need a 24 volt to 12 volt transformer in front of speed controlle
Answer:	The 3 wire connector connector is the same although they do come with their own pigtails which can be useful depending on how cleanly you disconnect the originals. In my experience neither fits "well" but struggle enough and you can get them in. The mounting rings of course are just different enough that you'll have to replace all of those. Enjoy!
Question:	Can it be used on a 12v / 24 lbs thrust trolling motor for a kayak
Answer:	These are NOT COMPATIBLE with BRK HD6135FB Heat Alarms so you cannot interconnect. IF you connect them, all alarms will sound immediately. It appears that BRK or First Alert no longer make products which are compatible with each other so try another product line if you want interconnected heat detectors with Smoke Detectors. I called BRK and confirmed this.

User questions & answers

Question:	I have a 12v ac/dc pid controler connected to a 12v dc brushless projector fan rated at dc 12v, current: 0.15a, will this speed controller work
Answer:	Yes, but this speed controller can only be used for 90V DC motors
Question:	What happen if the motor is working as generator, like in a electric car during stopping
Answer:	You can use this Drive, but you must use the 9860 Heatsink.
Question:	is 12 volts as low as you can turn this
