Hi /diy/
I have a 2000lbs winch which runs off a 12v, I think it's supposed to be mounted on an ATV.
Is it possible for me to convert it to run off 120volt DC?
I figure if I buy a power converter I could somehow rig it up safely. I'll post some more pics on how the power connection works
>>902507
So this is how it connects to the winch, and the other end should attach to a 12volt battery. That's the end I need converted to a plug I could plug into a 120v DC wall socket
Can someone recommend me a product to help me do this? Is it even possible to do safely?
>>902510
This end goes onto the battery
You need to find how much current it pulls at 12v.
>>902511
And the control switch is kind of in the middle of the wires.
My plan is to mount the winch to the back of my garage so I can haul my old snowmobiles (without reverse, old af), in back end first, then I can just drive them out.
So I want it to be able to plug into a wall socket
>>902512
Wouldn't a 120v to12v converter work regardless of that though? I don't know a heck about electrics, maybe I should have posted in the electronic general
The easiest way would be to get an old car battery wired up to a trickle charger. Then just wire it into that.
High current 12vDC power supplies are expensive.
>>902516
No, It wouldn't be able to provide a lot of current despite having the voltage.
I would GUESS that a winch like that would pull 20-30 amps at 12v when under load.

>The easiest way would be to get an old car battery wired up to a trickle charger
Okay, I actually have one of these for my ATV. That actually makes a lot of sense, thanks
It would provide enough power you think?
The trickle charger alone would not provide sufficient current. They normally put out around 4 amps.
But if you had the trickle charger charging a car battery which is capable of providing 100 amps, then you could use the winch off the battery.
>>902518
Im guessing, those things (depending on what your pulling) could prob draw 100A - so, youd be looking at a 1200W rated 120v-12v transformer.
As said above, test on car battery first tho.
>>902521
So I'd have to have a battery constantly plugged it? This is what I was trying to avoid
When I'm home tonight I could test the trickle charger
Depends how healthy the battery is. If you go and buy a new battery then you would only need to charge it every dozen uses.
However an old battery would probably need to be kept on charge.
>>902522
Would I be able to order something like this online?
>>902521
I think this would be my best bet

the amount of retardism in this thread is pretty surprising.
first of all, a wall socket is 120v AC, not DC. and how no one has pointed that out is beyond me.
second, this winch is 12vdc. meaning you can literally use any car battery to power it. an average car battery throws well over 25A continuous, which is what i'm assuming this winch will be operating within.
literally take any car battery and hook it up to the neg and pos and that's it. hook that car battery up to a trickle charger when you're not using it and there you go. the end. don;t listen to whatever else is being said in this ship of fools.
sourcing a power supply which will convert 120v AC into 12v DC and throw ~25A is difficult and will probably expensive. just find a car battery that's in ok shape, and buy a trickle charger. the end

Got it
>>902534
>the amount of retardism in this thread
whose fucking retarded, specifically? The only person who has confused AC & DC was OP, everyone else just took it for granted, if you are talking about 12v, you are not talking AC.
Speaking of retarded:
>well over 25A continuous, which is what i'm assuming this winch will be operating within.
- that is never drawing under 25A at max load (presumably, 2000lb) - as said, prob. nearer 100A. Dont make any difference, can certainly test it with a car battery - just, if you are buing an AC-DC converter specifically for it? Bigger the better, 25A is no way enough, end of.
>>902543
>presumably, 2000lb
I just need it to drag my snowmobiles which are like 400lbs tops
>>902543

go online and look for a 'CNC 12vdc power supply", I would get one with at least a 20 amp rating. pic related.
Then get a $5 grounded extension cord, cut the end off and use that for the power supply cord.
That's it. No battery of any kind required.
It would help first to see if you can find out the max amps that the winch draws, but 20a for a ATV winch is a pretty big amount.
NORMALLY I would say to get a power supply that had its own fan--but since a winch is only an intermittent-use thing, you can probably get by with a non-fan PS.
There is 30-amp 12vdc power supplies around for $50 on amazon, if the 20 won't cut it.
You may be stuck if you need more than that; I didn't find any that would give more than ~30 amps and you can't usually connect regulated power supplies in parallel.
I'd bet there's bigger ones but they will cost more than this project is worth really.

leaving a battery on a trickle charger?
ummm I think you meant "float charger" there, ace.... leaving a lead-acid battery on a trickle charger kills the battery
>>902548
Thanks anon I'll look into that tonight
>>902547
yeah, my (somewhat esoteric) soundcard breakout box also runs 12V AC. Apart from that, tho, fuck all else in the real world does, but, theres always an exception..
Still waiting on you googling up a 12v winch that draws 2000lbs at under 25A tho..
>>902545
400lbs, average car battery be fine.
>>902548
christ, we're at 20A / 240W now, and dropping. Somebody maybe check and confirm, how much these draw at max load? Sure if it was anywhere remotely as little as 20A, >>902543 would have mentioned the fact already.. Im certainly not arguing the point any further but, fug it.
>>902556
I'm at work managing this thread from my phone which is a pain
When I'm home in a couple hours I'll do some more research on the winch
>>902556
http://www.tscstores.com/2000LB-12V-12HP-CHAMPION-POWER-WINCH-P733.aspx
According to that page it's 1.2hp motor
>>902548
Is there a consensus that this will work? I'll order the pieces today
>>902556
>Apart from that, tho, fuck all else in the real world does, but, theres always an exception..
It's not uncommon for audio equipment to use low-voltage AC. Slightly easier to get a split power supply out of it.
>>902583
It will not work. You need to confirm that the winch will use only 20A first. Probably more. And I do suggest that you hook it to a battery which you will occasionally charge (it WILL die if you suck it empty!). Because eventually you will think "oh, I have this 1 ton winch, I'll pull that in" and it will be too much for your poor chinashit power supply and then it is gone... Or your snowmobile gets stuck on something and the winch suddenly pulls some more juice.
>>902563
1.2hp is around 900W, 75A at 12V. For a mains powered 1000W 12V PSU you're looking at around $200 from what I could find.
>>902600
May as well buy a new winch
I'll try the battery idea with a trickle charge
Thanks for the help

It depends entirely on gearing. Gear a winch low enough and you could pull 10,000 pounds with a 50W motor, it'd just be really damn slow.
Not going to bother bumping
I bought a hand crank winch for $60, so I'm going to use that instead. It is too much of a hassle and expense to use the electric winch
Thanks for the help
