Hello everyone,

I'm a noob to electronics, but after quite a bit of searching and reading through all of Gary's (single-plug) Hyperion topic:
http://endless-sphere.com/forums/viewtopic.php?f=14&t=23362

I believe the Hyperion 1420i would be the best way to charge a Lipo 10s battery pack with just one plug into the pack (see Gary's post about making just one plug charging with the Hyperion).

It's my understanding that the Hyperion doesn't just plug into an AC outlet and instead needs a 24V supply (or 12V?). On Gary's post people mention a few different ways to power the Hyperion. Gary mentions using two 24V Meanwells in parallel for his set-up, and also mentions it can be done with just one.

I would like to know what would be the best way to power a Hyperion 1420i to safely charge a 10s15Ah Lipo pack.
I don't necessarily need to take advantage of the full 20A max of the charger like Gary does, so I would like to know what some of my options are, even if that means a slower charge time... I am mainly looking for reliability and safety.

*It would really help if you posted a product-link to the power-supplies that are mentioned. (because I'm a noob and I really don't know what I am looking at when I do a google search).

Thank you for your help.
-And thank you Gary for your single-plug Hyperion post.
 
You're looking for a 24V DC power supply that is capable of 25A (600W) output. I found a used one on ebay I got for ~$21 shipped. Good luck finding another deal like that. Or 2 that you can parallel together for at least 25A total. Like 2 13A ones.

Thanks. I could potentially just get one and charge at half the Amperage correct? I'm more concerned about quality and reliability than charge-time.
 
are there any specific brands/models I should be looking for?
any I should avoid?

Thanks.

You can do about anything you want as long as the PSU is at least 12v. Until I got my PSU, I rigged up the 12v output of a PC psu. It worked ok but charged at a snails pace. A single 350W 24v psu will work fine, just be slower for a 15ah pack.
 
Thanks. Sounds like there are endless possible PSU's.
it just seems the MW is the most used power supply for the Hyperion.
So are all MW psu's created equal?
or does their quality differ from model to model?
 
I use a Meanwell SE-450-24, 450W 24V Power Supply to power the Hyperion 1420i. EPbuddy.com was the vendor. The 1420i is used to charge a 36v 20Ah Headway pack. The SE-450 allows a max charge of 7 amps. The charger is a little finicky at times but is the best solution I have found to get a full balanced charge.

Good Luck,

Barry
 
Just as additional info.....

I am driving my hyperion 1420i from a 12v supply (a modded server power supply)

My PSU is 55A at 12v but the Hyperion will only go as high as 40A at 12v. (there is a setting in the menus where you specify PSU input V & A)

At the max setting (40A) with my 14s pack, I get a max current of 3.85A on the battery side. This is enough to recharge my pack (5ah) in 45 minutes.

I actually bought 2 server power supplies for $8 each to run in series for 24V, but I ended up leaving one at home and one at work, because I have such a small pack. 45 minutes is enough for me, and even when I go to 10 or 15ah, 3.85A will be fine for me I think.
 
If you are looking to charge 10S, you might also consider the Icharger 3010B, which can be bought from Hobbyking.

I have both that and the Hyperion 1420. The Hyperion is probably a superior charger, and would offer the benefit that if you move up to say 12S, you are still able to charge as a single pack, but I bought my 3010Bs because my Hyperion had started to do this weird thing where it sometimes report a "Battery Connection Error". I actually have two Hyperions, and both started doing it erratically. I cracked the sh&ts and just bought two 3010B units, and I really like them. You will notice that on the Hobby king website there is reports of them bursting into flames, that put me off at first, but I caved and figured what's another fire risk in my house? And my eye brows are still in tact, and my children are alive.

You might say you don't care about charge times right now, but trust me you will. Make sure you have enough grunt in your power supply, i have a 26 volt 30 amp PSU, because I am an angry and impatient man, and like Homer, when told that something can flash fry a buffalo in 30 seconds, my response is "But I want it now"
 
I guess that is the Simpson type Homer and not the one that wrote The Iliad? :)

Correct, there are the classics, and then there are The Classics....

Well sometimes it is hard to tell which is which. :shock:

I know it is a lot cheaper to underpower the charger, but that seems a waste and for many will lead to a second power supply purchase down the road.

I say, buy once.

I suggest getting a power supply that comfortably powers this charger. This means getting a power supply that exceeds the input power requirement by 20% or more. Some power supplies, especially cheaper ones, aren't too happy running near their power limit. And the charger itself is probably a bit more comfortable running at say 27V than 24V, so you might consider this as an output voltage for the power supply.
 
Ok, I found 2 potential Mean Well's:


http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_693628_-1
SP-320-27: Output 27 Volt 11.7A 315.9W
74.95


http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_295911_-1
SE-600-27: Output 27 Volt 22.2A 599.4W
114.95


I imagine either one of these would work, speed isn't necessarily what I am going for. I just want reliability.
Does anyone else know of a better source for MW PSU's ? (other than the china ones on e-bay)

Thanks.
 
I got two server supplies for cheap to wire up in series for 24v like this:

http://www.rcmf.co.uk/4um/index.php/topic,67706.0.html

I only have 5ah of lipo right now, and I found I can charge that in 45 minutes off one power supply....so I have one at home and one at work, and I take the hyperion with me in my backpack.

Once I buy more ah, I won't need to charge at work so I will bring that one home and do the series mod.

I paid under $40 for both the supplies including shipping. Might have got them cheaper if I bought them from someplace that combined shipping, but I bought new ones from two separate vendors.
 
24VDC is fairly common in telecom equipment. Might search around for an old telecom switch PSU. I lucked out and got a used 24V 600W PSU off ebay for $21 shipped. had to add a power cord, but it's heavy duty and works great.
 
Thanks guys. Those are all good suggestions. But I was hoping to pick up something new (sorry I didn't mention that). So it looks like that SE-600-27 will work.
I imagine that PSU would allow me to get pretty fast charging w/ the Hyperion (a quick guess would be in the 17A range) which is plenty fast for me, so I'll likely tune it down a bit and run 15A through the charger.
 
hello guys
I got my 2 hyperion chargers and I still look for the best power suply :wink: and i found this

http://www.trcelectronics.com/Meanwell/rsp-1000-27.shtml
will go better then 2 power suply s 24v 350w or 450w or 500w :?: and the price for them to
my battery pack will be 8 of zippy 22v 8a 4 in paralel and series to go 48v 32a

I wish to exist a list with power suply for hyperion . with the best one until last posibil to use and price for them.

and if it is posibil with picture and links . will be a good tread for the nobies like my :oops:
and you can have option to buy what you need and {money} for your battery pack :mrgreen:
 
That's a nice supply, but pretty pricey. I'd go with two 350W 12V MW S-350-12 in series. These can be found pretty cheap. This is better, in my opinion, than using two S-350-24s in parallel, because for the latter you have to get the output voltages exactly the same for the pair to share the load.

Just got a Hyperion EOS 1420i NET3 Charger. Need to buy a power supply. Those Meanwell's look a bit unfinished. I would like a nice looking power supply. What do you all think about this? I am a electrical idiot. Is this power supply good? bad? stupid?

Well that power supply will surely power the charger nicely, the question is, do you really want to buy a laboritory grade power supply which im guessing is something like $300-$500? just to power your RC charger... if you want to use it for all other things as well then i guess its ok.

on the note of reliability... The main thing you have to remember with ANY power supply is that if you want reliability then you have to overspec. if you want to power something that pulls 500w then you want a 750w minimum. Running a PSU at its rated maximum capacity is going to mean a prematire death for sure. My charger is a 250w Icharger that i run at 200w max and is connected to a 350w PSU, even at these settings both charger and PSU gets warm during charging so at maximum i can see why things fail.
