Hi

you could use a couple of ex server psu, available on ebay, link a few control pins and the current share pin 150 amp upwards @ 12 volt

I think you will still need a battery in circuit to absorb the back emf

If you want to go this way I can give you a link to the RC web site with details

Hello,

here are 2 links well documented for using serveur PSU :

The mod is very light! https://sites.google.com/site/tjinguytech/my-projects/HP47A and here http://www.worldwidedx.com/general-ham-radio-discussion/121243-server-power-supply-conversion-cheap.html
There is not need to open the block and therefore no risk of electric shock.

I used this one for my sim :
eBay, the DPS-600bp model (http://www.ebay.fr/sch/i.html?_from=R40&_sacat=0&_nkw=DPS-600pb&_sop=15) is 30 € with shipping: 575W

Hi

If you want 24 volt you need to wire 2 psu in series and will have to isolate the -tive output on one unit from earth to avoid a dead short

how easy that is depends on the psu, on the dell psu I use, I have drilled out the captive nuts holding the pcb and remount using nylon nuts and bolts.

tks a lot !!!

We have 4 motors. Three of them are of 14A 350w and one of them is 27A 500W. The total absorption is 1550w. I want to point out that the motors
don't work continuously but they alternate, so the absorption won't be continuous.So the answer is does it go well the feeder that you make me
see? Thank you

24V x 14A = 350w and one of them is 24V x 27A = 650W not 500W

1700W -> 70A !!! i haven't seen on the internet "cheap" PSU with this intensity... you will probably need two of them !

[thecure]

yes !!!i don't remember....if i use two of this https://sites.google.com/site/tjinguyte ... ects/HP47A the current is 47 Amper + 47 Amper = 94A ? tks
