need some advise...
i have been offered a 2000 watt power supply unit,
now can i use this to power my chargers?
and if so how?
would it work ok - is it safe, i have no idea about this hopefully someone here does :)

Give us some information. If it will give 12V to 15V at a few hundred amps then you just connect up your chargers to it. Wire each charger back to the psu with its own cables. You might need a junction box with short thick wires between it and the psu and normal wires to each charger.

hey Chris, got your files to send you but i dont know how to add them on here ?
do you have any idea lol, if not i can always put it onto disc and send or drop off to you, as your only a few miles up the road and i'm always heading into farnborough most weekends so not to far at all.

As for psu i have no idea what you put, its all double dutch to me lol

Easiest thing is to put them on a cd and post it. Unless you know how to upload using ftp. I've got a website. One of those free ones. Haven't tried out the FTP yet. Second thoughts perhaps cd/ dvd is best.

What sort of power supply is it? How many volts out? Does it have a name? If it's a computer one then it will need some fiddling.

ok ill stick it onto a disc and post it to you :)
as for the psu, this is all the info i have on it right now

[FONT=Arial]Power supply for IBM unit made by Delta Electronics. Model number DPS-200BBA, IBM part number 74P4452 and FRU number 74P4453. Stated as 2000W[/FONT]

[FONT=Arial]hope this helps :)[/FONT]
[FONT=Arial]if you can send your address ill post it later today :)[/FONT]

What charger have you got Gazza? unless you got something like a powerlab, Hyperion or Voltz.. wont it be a waste? No point for a 50w charger.. you'll probably kill it?! :)

[gazza131]

I have the following chargers

Hyperion Eos 1210i
imax B6
prolux 3839
Mystery cx450-50-01
pro peak varipulse 2500vp
pro peak E0-6+

maybe your right about overkill with the psu :)

I do have a couple of other psu's which are
skytronic 20volt / 20amp adjustable dc power supplys
But these light up but no output ?

[Eckchaz]

I'm no expert mate but looking at your list off chargers.. the best one is the Hyperion at 180w? all the others seem 50w... and your getting a 2000w psu for it? :D

Again my chrager knowledge aint as great as other members but surely if you cant adjust the W to the charger, its going to be some bad news! If its a good deal, I'd say buy it for the future and them get something like the Powerlab8 etc to make the most of it! ;)

[gazza131]

okie dokie, the guy wants about £30.00 for it, sounds cheap enough to me, and may be worth getting like you say for the future, anyways thanks for your help Chris, oh send me your address so i can send this disc to you :)
cheers

I'm not going to claim any expertise either, but in basic terms, the charger 'sucks' amps, the PSU 'pushes' volts. Amps x Volts = Watts.

A higher wattage PSU than you need is not a problem, a higher voltage PSU than your charger can handle would be :)

So on the PSU end you need to ensure that the output voltage is within the limits that the charger can accept.

On the charger end you need to be sure that the charger is not going to try and pull more amps than the PSU can safely supply. (some chargers have a current limiting feature to help with this.).

I really wouldn't rush to buy this one unless you can find a guide on the net for converting it (or someone willing to do it for you).

This is a PSU designed to go into a blade chassis, it is not small and it has no external wiring so you are going to have to open it up and modify the internals. Not uncommon with server PSUs but it is not a trivial task unless you know what you are doing.

These can be found on eBay pretty cheaply as well so £30.0 is not a particularly special price either.

[gazza131]

awwwww hmmmm ok, maybe i am trying to run before i can walk here, ok maybe i will forget about this psu, i think ill just get the other 2 repaired as i should think they are more than good enough for what i need right now :)

thanks chris for your help and input, i would have just brought it and not been aware of what a waste of time and money it could have been.

Cheers

Looks like these power supplies give 12V. I've looked at specs but I expect everybody knows they are 12V so don't bother to say. They are hot swappable so there is probably stuff that needs to be modified. Probably not that big a problem once you find the video. I'm sure people on here use them, but I've done a search and can't find anything.

They sell for about £500 new so £30 seems a bit low. I suspect that they are faulty in some way. Perhaps they only give 1900 watts. Definitely over the top for what you want.

Volts is like a push, but more like a pure force. It's not movement just strength. Current or amps is like water current its a movement of electricity bits through the wire. A 12v 2000W psu will push with the same force as a 10W one. A 12v 12W psu will give 1 amp. For a 5 amp charger you'll need more than 60W, probably 100W would be ok.
