The circuit you showed at ~21:00 is not going to work. It states on the listing that it takes 12V DC in and converts it to 12V AC (an inverter) but to a square wave, not a sine like normal city power AC is, so I would not bother with that. There are at least two scenarios on how to get this working then. If there's an AC motor in there then you need your own external rectifier which is just four diodes arranged as a full-bridge rectifier and then a big enough smoothing capacitor on the output. If there is an internal rectifier driving a DC motor then it should work being given DC directly, though with the associated power concerns that @ElarSaar pointed out, or alternatively you could open it and bypass the rectifier.
I do believe it is an AC motor,,, I did see the "square wave" in the description of the DC to DC converter. That would be where I might think smoothing capacitor,, to improve on the wave, If needed, depends on the motor. I have no idea, where this "full-bridge rectifier" comes into the picture,, as I want to go DC to AC,, not the other way.. :-/
You missed that I was off on vacation, and I drained the pool right after filming! Putting chlorine and Algaecide in the water and draining it in to the ground,, is a doubtful practice :-)
Thank you,, not all movies have a happy end,,,this one might get a sequel though, but probably next year as it's getting too cold to have a plunge pool.
put a cap on that pipe above the water. drill a msall hole in it to still get air in. you should get more water through the pipe and the bubbles should go away
Or just make the hole for the water a bit bigger.. I drained the pool before I went on vacation.. I do not thing it is worth it to put water in it when I get back,, too cold.
Of course you can use 12V DC to power 12V AC gear. And no need to worry about polarity. Only concern is that 2 diodes out of 4 in full-bridge rectifier will do all the work. Meaning that they will get two times the thermal stress.
I do not think this will work,,, the motor apparently uses the 50hz for making magnet fields,,, and have them turn on and off,, I cant do that with DC... ???
I would be very surprised if there would be an AC motor inside the pump. As other people pointed out, it probably has a rectifier inside the pump. They don't put this rectifier with the transformer because it's a bit of a hassle. The transformer is just a block of iron and copper that downscales the 230VAC to 12VAC.
I think you might just want to move on,, this was not sponsored. I tried to fix a issue I have with the Power station using to much power converting from DC to AC, by getting a 12V DC pump,, and I clearly messed that up.
It's always the simple projects. 😂
One tiny little thing,, that you over look,, why even run AC :-/
Bit of Chlorine?
I drained the pool after recording this,, as I was off on 3 weeks of vacation.
I remember something about ac pumps being way cheaper to manufacture...
Any handheld power tool has a DC motor,, they are not that expensive...

You need to shock (high dose of chlorine) to kill the algae (green stuff) and then maintain a sanitiser level.

Credit where it’s due for publishing this !

Add a 12V DC ultraviolet system in parallel to your filter, or get an all in one filter/UV for an aquarium / pond.
I do actually have one :-) ahh okay it is 230V AC...
Just FYI those connectors are standard waterproof screw on connectors.
Okay,, I have see many different sizes..
It might be a “universal” motor that will work on d.c. perhaps has diodes where they’ll be water cooled.
I did try it on DC,, it did not move :-/
Had the same problem.. realy dont know why there is no DC variant. 😅
There is good DC motors in any battery hand tool,, why not use that...:-/
✋ Hello sir, very beautiful work, you have to put in a lot of work to always be beautiful, I see that you are doing very well, congratulations ⭐🏆⭐👍
Thank you very much
if you try it on dc some motors do work on dc test to see if there is a diode in the in the motor set up if it fails to see if it could work on dc
I did try it on the DC 12V,,, did not move :-/ it is an AC motor.
Use a mosfet to create a squarewave.... Should be enough to drive the pump. 🤷
I ordered the thing in the description,, I do think that is just about that that does :-)
Of course you can use 12V DC to power 12V AC gear. And no need to worry about polarity. Only concern is that 2 diodes out of 4 in full-bridge rectifier will do all the work. Meaning that they will get two times the thermal stress.
I do not think this will work,,, the motor apparently uses the 50hz for making magnet fields,,, and have them turn on and off,, I cant do that with DC... ???
Did you open up the pump? Was there rectifier inside? 12V AC motor seems unlikely to me.
I would be very surprised if there would be an AC motor inside the pump. As other people pointed out, it probably has a rectifier inside the pump. They don't put this rectifier with the transformer because it's a bit of a hassle. The transformer is just a block of iron and copper that downscales the 230VAC to 12VAC.
I do not think so,,, I think it is an AC motor,,, and it uses the 50Hz to work at all... :-/
Another product video AGAIN! Suggest to drop this ads channel...

am i awesome firsst?

Feed that pump120vdc and then return it.
Nahh,, I did order the DC to AC converter and looking forward to checking it out.
