No problem next time I'm at our field probably tomorrow I'll bring a tape measure and scale. I built this one to leave at the field for anyone to use.

The pinout instructions are here http://static.rcgroups.net/forums/at...l%20pinout.jpg

Pretty simple to jump them on

How hot do those get Oliver? I found the HP DPS 1200's heated up a fair bit.

They don't seem to bad even at 60 amps (well 59. Something doesn't quite hit 60amps according to my duo) I've typically used these at the field so I didn't really pay close attention like the one I have on my desk. My dells seem to get hotter.

Thanks Oliver. I am going to try those if I can get the guy to come down on the shipping. He lists UPS ground which to Puerto Rico is not technically possible unless the guy drives 1200 miles in the ocean. They will still ship it but it has to go air. It says $60. I hope he will ship USPS flat rate.

No problem it's the price you pay for living in paradise Hopefully he'll hook you up on shipping. They are super cheap I may pick up another set just to have. I make them to give to new guys in the hobby.

They're smaller and lighter than I thought. The case dimensions are L12" x H1" x W4" They're duct taped together so both of them together weigh 7lbs.

I have two Dell 6650's PSU. These are bulky and heavy. They have a floating ground already.

I followed a setup similiar to this:

https://www.helifreak.com/showthread.php?t=361840

They are $25.00 dollars each on Ebay and together provide 1800 watts at 24 volts. This is perfect for a generator setup.

You could buy 20 of these for the price of the Meanwell PSU.

Thanks for the measurements Oliver. Weight isn't a huge issue but damn those are heavy. The DPS as stated are super small. I don't think I can go to something bigger and less watts. Price is good though.

Yeah didn't realize the dps were so small. Look like nice psu's. A little more money but definitely more portable. I'll have to try the 1200's at some point but I really don't transport psu's I make them and leave them at the club at home and at work so cheap is good. That way I can make more and it's one less of thing to transport.

Thanks Oliver. As Michael said the 1200 is rather light and compact compared. Justin has a good writeup about floating and adjusting the output in the tech tips here. I got 2 for $42 total with shipping off ebay last night. Looking forward to setting them up. My new case will be lightweight .

Just picked up some 1200's man they are crazy small. The boards were a little damaged in shipping so the seller refunded my money. We'll see If they still work. Impressive little unit though it's not much bigger than my hand.

Oh well one is toast the board must be damaged internally from the impact it doesn't turn on. The other seems to be ok we'll see when I take it apart. Super quiet fan too on top of being so small I'm impressed.

I have to say you guys are right about the 1200's. Super small I can easily drive two chargers at 30 amps each or one duo at 60-70amps
I bagged making a 12v output and did dual 24v ports that way I can drive two single chargers. I haven't maxed it out yet but I plan on hooking my pl6 at 40amps and a 306b at 30amps to see if it can push 70amps total with all my stick packs.
A lot more expensive though I can do the delta 750's for $10 per these are more in the $30-$40 range per.

I actually lay the 1200's side by side. Since I have a charging case in which I use an icharger 308duo, it makes for a slim install and uses less space since the charger is on top of the psu's.

That works. I don't use my case anymore I just bring the charger in my heli bags. I made a psu and just leave it at the field. One less thing to take.

My poor little DPS 1200's get about 120 degree's (measured with an IR into the fans at the internals)

Is this too hot??

Charging at 20 amps per channel on my 308 Duo

Nah they're enterprise class psu's they will shut down before overheating. I've overheated some others in a poorly ventilated case no big deal just let them cool and fire them right back up. The 1200's do feel warmer than my larger ones but the fan ramps up when I have them charging at 60 amps
