For Sale
28V, 52 amp, 2000 watts dc power supply !!

I picked up a few surplus Power-One power supplies, and I'd be willing to part with a couple.

Here's the specs:
Model: HPF3E
Input: 85-254 VAC
Output: 2000 WATTS max, 28 VDC, 52 AMP

These are aerospace surplus units, brand new in the wrappers. They run more than $600 used for industrial applications. I got a good deal on them which I'd like to pass on to fellow hobbyists.

Make sure you consider the power and quality of these; they'll easily charge large capacity lipos at 5C. My Hyperion 720i doesn't even begin to tap into the available power, even when charging a 6s 2650mah pack at 4C (4C maxes out my 250 watt charger). I could hook up 3 720i's to this. Since this has 28V output, at max draw the 720i only draws 8.9 Amps (250watts/28V = 8.9A) of the available 52.......

Owning one of these guarantees you'll be prepared for the next wave of high powered chargers! I can't imagine ever outgrowing one.

Looking for $300 plus shipping within the CONUS only, paypal please
