I just ordered the Hyperion 615iDuo3 charger
http://www.hyperion-world.com/produc...P-EOS0615iDUO3

So now, I'm going to need a good power supply to power that baby up! Does anyone have any good suggestions? Right now I'm looking at this one by Protek Super Pro 40
http://www.amainhobbies.com/product_...-138V-40A-520W
because I'd still be able use my other charger at the same time as well, (ProPeak Gallant) though with a duo, I probably wont need to run the other charger, but it's nice to have the option incase a friend forgets theirs or something. Anyway, I was told that I should run a minimum of 30A power supply with this charger. Any good suggestions? I didn't realize how expensive they get once you're talking about good strong Power Supplies. I'm trying to stay away from those $200+ units after dropping over $200 on the new charger itself. Thanks in advance!

If you want to save some money check your local craigslist or kijiji for used power supply for amatuer radio, hobbiest, etc. You don't have to get a RC specific power supply since power is just power. Just look for the amperage you need. You should be able to find something cheaper and probably more robust than these R/C power supply.

Their other PS, the "Pro 40" vs the 'Super Pro 40' would be just as good and a $20 power distribution box would provide addiitional connections to the supply for less money in case you ever needed additional connections which doesn't sound tooo likely. Either of these is 540watts and thats more than you really need for a 360watt Duo3. You only require something in the 430-450watt range to run it a full power.

If you don't need to run it at full power, you can easily get by with a less powerful, less expensive supply as long as it provides about 20% more power that your charging requires of the supply. So if what you're charging at most requires ~150watt (6S 6000mah for example), you'd need a 350watt supply to charge this with both ports.

no need to get fancy and spend big bux, been using the ones I have for several yrs and payed $30, PM me if ya want some info

If you want to get full power out of the Duo, none of the mentioned supplies will quite do it.

Due to input current limitations the charger will limit available power when used with a supply below 15 Volts. The typical ~13.8V bench supplies, and especially the ~12V computer derived supplies will not allow full power. It’s best to use a ~24V supply for high power use.

It will work with the mentioned supplies, just at a proportionally reduced power level.

thats interesting, been using a P/S I payed $30 for new and it powers a 4 bat lipo charger, 300W 20A, no complaints Atall cant understand these guys schelling out $100+ for some name brand when you could pay $30 and get the same thing for the same purpose, makes no sense

For a smaller charger that supply is fine. But it simply won't power a larger charger like the Duo to full power. If you don't need the full power then again it's fine. I actually use a slightly smaller supply than that on a Duo right now, but I will need to upgrade if I jump to larger batteries or higher charge rates.

Not to mention many of us power more than one charger from a supply, and other things besides chargers.

12v power supply. Based on computer server. Reasonable price.

heres the one I mentioned maybe itll work for ya and maybe it wont 20A 300 W......been charging 4/ 5000 2s at once off of one unit and it works fine, cant go wrong for $30

I didn't realize the Duo3 has to have an input voltage of 14.5+v to produce full 180watts of power per port. It took a little looking, but I found where the Duo3 had been tested both with PS with > 15v and PS with < 14.5v (RC Groups). Duo3 produced 180watts as advertised with a 14.5+v input source ( 18v was used in the test I found) and it produced 160watts of power when sourced with a 13.8v power supply. Thats a little over an 11% power loss if your supply isn't running at 14.5+v.

The GT350 is a 14v supply and the FeatherMerchant PC server supply is 12.2 or 12.4v (forget which). Neither would give you full power from a Duo3.

I'm using the FeatherMerchant supply, its running my iCharger 3010b and is enough to enable the charger to produce 500watts. That charger requires a 24v supply to produce its full rated 1000watts. Its more expensive that some of the other PC server supplies yopu can find on eBay, but the chaeaper ones seem to have a very loud fan. Mine doesn't, you can barely hear it running.

So if im buying 2- Checkpoint TC1030 and charging my 5200mah 2s @ 5.2 amps would a 20 amp power supply be enough power for both chargers or should I use 25 or 30 amp.
Thanks in advance and sorry for the thread jack

The charger and pack capacity is kinda irrelevent. A pair of 2s pack at 5.2 amps uses around 90 watts.

So I jacked the thread too,

ps 88 watts / 12 volts = 7-8 amps and you can do the same job with only 1 TC 1030 because they are 120 watt chargers. I use a similar set-up with a 150 watt ps and a TC 1030 running at 120 watts (10 amps on 2 3s packs together)

Keep the calculations simple.....5.2 a x 2 = 10.4 amps....
you want a power supply with greater than 10.2 amp capacity....
12 amps or greater will be fine.
