My Powerlab 6 charge station :)

Id like to use the Dell Poweredge 2950 750w Power Supply but I can't find a pinout diagram for it. Its got the same pin layout as the 700W PSU for the 2850 though so I'm guessing the pinouts are the same and I do have a diagram for those. I already have a pair of the 550W 44A ones but I can't run my PL6 full tilt on 6S with that.
 
Essentially you could do the tedious task of tracing everything out from the hotswap board, You would need to find a positive and negative source on the hotswap that goes back to the main board (besides your +/- outputs for the charger) and then ground those out to a -12v source. It's quite possible that the pins could be labeled on the board. If you can get one cheap then it may be worth trying to figure out.

You would need to figure up the resistance and wattage of the fan using ohms law. Then select a linear potentiometer that matches close to your equation. The higher the ohm the slower it can spin the fan. On the pot there will be three connections the middle one is the slider. Connect the + from the fan to the slider and the connection the slider turns toward will be tied together then ran back to the fans 12v source. This should allow you to control the fan speed. I imagine you could put the pot between the fan speed pin and a ground source and it create the same affect. I didn't add a pot to mine, they run full speed. I did buy slower n slightly smaller fans though to cut back on the noise.

You can also just short the fan speed directly to ground and it will slow the fans permanent, they will still speed up on there own when the PSU gets to a certain temp. At least that's how they work on the ones I have.

So If I connected a pot to the pin and then to a ground source could U use the same pot for both PSUs for example tie both pins from both PSUs to the same pot? Also when you say hook it to ground do you mean the original fan ground or could I just hook it straight up to the ground lead of the PSUs?

Follow up question as what little bit I know about electricity and electrical components has been self taught. So if I understand you correctly on how to choose the right pot to control the fan speed I would need to divide the voltage of the fan by its amp rating to get the ohm rating of the pot I need? If this is true then I know from memory that I have 80mm PC case fans at home that are rated at 12V and .14A so these would need (roughly) an 85 Ohm pot in order to control them properly?
 
I thought it would of been best to keep the fan running at 80-100%, then it's just the use of a one,two or three diodes in series to drop the voltage to where you want it. 10V sounds good.
 
I picked up a Fan speed control unit that controls up to 4fan. Its adjustable from 6V-12V Thats what I'm gonna use. Depending on the ambient temps outside I may not need to run the fans full speed but mostly its just bling. :)
 
Thanks man. I had no idea this mobile set up was going to cost so much. I've got nearly $150 bucks in it and I still havent even bought the case. I have an ebay bid in on one of those pelican cases like you used for $60 bucks right now. I hope it doesn't go any higher. I had no idea this thing was gonna cost this much...At first i though maybe $100 bucks...lol Although it should be bad ass I'm putting all kinds of bells and whistles on it :)
 
Sweet man! You can grab the pelican case like mine for like $67 BIN from a seller on there and he offers free shipping and a free name tag for the case. Make sure you get some pictures so we can see what you came up with :)I tried to keep mine as simple as possible but maybe down the road I'll add some more bells and whistles.
 
Yeah it can get pricey....I weighted options of getting a mean well powersupply and no case or using the server supplies and putting the rest that I would of spent towards making a case. I'm glad I went the case route. Its nice just picking it up and knowing everything I need to charge with is nicely tucked away inside.
 
Well I bought a Pelican IM2750 case for my station and it arrived today....Houston....I think we have a problem.....DAAAAYYYYYUUUUUM thats a big case..... I may have bought one a little to big O_o I read the dimensions but for some reason I didnt realize just how big it was. Guess I'm gonna have resell this and rethink the size of the case. I guess I was mainly fixed on the lid depth as one of the mods I want to do I need the lid to be at least 2-3 deep but the rest of the box only needs to be about 6 inches deep. The ebay picture was generic with no point of reference. Oh well, back to the drawing board.

Ouch, sorry about that, I'm betting you could return for your money back. There are other companies out there that make similar cases to pelicans and progressives cases. Search for Injection Molded Cases - This is one of the companies I almost bought from - http://www.ameripack.com/pelican-cases.htm

Sweet I'll look into it cuz all of the pelican cases that I saw had very little lid depth. at least until you get up to the point where the rest of the case is just way to big lol.

I've already resold it. In order to return it I was going to have to pay $30 bucks in shipping. I manged to only loose about $10 bucks on it reselling it. Probably could have gotten more out of it since it sold in under 24 hours but who knew?! lol

Hey nice case. Where did you get the plastic brackets that the top shelf screws onto? Also, is the powerlab just resting in the cutout on the shelf? How do you have it in place?
 
Thanks, they are made by Pelican, if I remember right they were called Peli Quick mounts.

Yes the charger is just sitting into the cutout, it has 4 tabs on it (two each side) that are used to connect multiple chargers together. Originally I planed to use nitro fuel tank mounts on the tall side and run screws through the screw holes but I was afraid the plastic would break and I ended up storing cables below the deck and wanted quick access. So I put some fuzzy side of velcrow to each side of the charger to give it a snug fit. Worked out pretty good, doesn't fall out even when I bang the case around.
