Best power supply I've had yet!
I had to share this with you guys. I've been electric for years with 2000+ Watt charging setups. Initially I had a 2s2p setup of some Dell 500W server supplies, then later went to 2 Dell 1200 supplies in a 2s setup, which I've been running for about 2 years now happily. The only drawback to the ones I've been running is that they are loud enough to sound like a vacuum cleaner at all times and never ramp down the fans.

After hearing about the HP DPS-1200FB supplies on the RC Heli Nation podcast I had to give them a try. WOW! These things are 1/4 the weight and size of the ones I've been running and about half the size and weight of the 500W ones. The fans ramp up and down with load so they are nearly silent when I'm charging small stuff, but ramp up to a dull roar (still quieter than my others) when maxing out both channels on my 308 Duo. With these I am able to go back to a much smaller charging case than what I've been carrying around.

I couldn't be happier with them, a pair was $46 shipped from eBay and the conversion took about 5 minutes. Check them out if you want to lose some weight and size from your charging setup. On the 120V I'm feeding them out of the wall or generator they are capable of 1800W at 24V. More than enough to shut down my 2000W generator or pop the breaker in my house if I attempt to max them out.

I was about ready to buy some 600DP power supplies done up from Solid Hobby, until I heard the RC Heli Nation podcast about the 1200FB. So I ordered two. I shorted one out, so I ordered another and got them working the other night. These are quiet and powerful enough to max out my new 308 DUO.

I picked these up for my icharger 3010b and they work flawlessly with no issues. I plan to get another set for an additional icharger.

Yes, the jumper on it is just for 24v 1150 watts or I can use one or both to power seperate chargers.Minicopter Diabolo 800, Minicopter Triabolo 700, Minicopter Diabolo 700, Minicopter Diabolo 600, Minicopter Diabolo 550, Goblin 770

Thanks,

Same as I use for everything else. All my stuff has Anderson Powerpoles, so I soldered a short length of wire onto the power supplies and put some Powerpoles on those.Nick Crego

Just wondering if anyone can tell me what size nylon bolts and nuts folks are using to float the board? Or better yet, if anyone has a pic of the nylon hardware that they are buying at home depot that would be great too. I'm not really sure what size drill bit I should be using to drill out the metal case and the CCA (circuit card assembly).

I just pulled out one of the screws holding the board down and went to Lowes Nd bought something slightly larger and longer along with matching nylon nuts. Use a bit that matches the siZe you buy, you can use a wide variety of sizes. I did mine with 3/8 x 2" nylon screws iirc. Then put the screws through the board then tightened a nut under the board to space it from the case, then screw through the case and another nut. Cut the screw off flush and it was good to go.Nick Crego

Nick,

Thanks much for info/update, simple enough. Those nylon inserts on Heli nation kinda threw me off.

Have you guys tried using three of these for 36V?
I got mine wired up. When I test the the grounded supply shuts down and the two ungrounded supplies continue. I have used a 1K resistor. Maybe I should try a 600ohm?
