Hyperion 0610i Charger power supply

[BrianG]

If you try to merge the rails, be careful. I had a dual 12v supply and heatsink got quite hot quickly. Each rail would have to have EXACTLY the same voltage and even then I dunno.

Some PS units have a trimmer pot located somewhere on the PCB. You can use this to tweak up the voltage a little. I have one I was able to get to ~13v unloaded. Not only does this help keep the voltage above 12v when loaded a little, but the higher voltage requires less current at the same time. Be careful though, if you do see a pot, make SMALL changes while watching the voltage. If it doesn't change, put that pot back to the original position because it's being used for something else.

If the trimmer pot is not there, you can sometimes force a little better regulation by adding (or increasing) the preload on the 5v and/or 3.3v rail.

It sucks that all PSUs are not built the same because what works for one doesn't work for the other...

well i was brutal before putting it together (its still sitting on my table 1/2 finished) and ran it hard with both rails loaded as much as my 4 chargers could... it got warm after 5 mintues but i wouldnt call it hot. just warm to touch (dont have a temp thingy)

ill have a look for that pot... this could help heaps. are there any downsides to turning this up or is it just there so they can accureately tune it at the factory to make sure even though the components may differ in quality it still outputs correct voltage?

anyone with electrical knowledge please help!!

here are some pics of the underside of the board. there are no pots that i can see, are there different types which look completely different to those commonly seen? thanks

see how closely the 2 rails are divided, do you think that there would be any way without blowing it up to try it?
o yeah i forgot... the 2 smaller blobs near the side, in the middle of photo 1 are the 12v rails... the other HUGE blob is the common rail. hope that makes sense!

yeah i was planning to turn it off use an insulated screw driver (wait till the voltage hasdrained from the caps of course) then adjust it a 1/16 of a turn or something then turn it on and re measure. im not keen on touching it while its connected to 240v!!
btw, where would the pots be??

well i decided to try my luck again on fleabay i ended up with a radio shack 25 amp 13.6v power supply anyone have any feeback on my purchase from personal experience knowing that it is from radio shack.
oh to keep it in perspective it was 70 bucks shipped and it looks brand new

this is going to be enough power for my hyperion 0610i charger correct?
there is no other spec i should have looked at just amps and volts, yes
thanks

IIRC that supply is made by Samlex for RS and has an excellent rep as a PS for rc use. The way Hyp specs PS for the 0606i is 350watts at 15v. Specs you quoted is equiv 340watts. Gotta believe you'll be able to do 95% of everything you want to with that one. Thats the one I wanted when I was looking for mine, but took a new 20a PS by ProPeak in a trade and so far, its been all I've needed.

Well, you can try paralleling the two rails and watch temps. It might run fine, it might not. Also, if possible, get a voltage reading under load when seperate and then again while paralleled. It should dip less when paralleled. If not, then you aren't gaining anything.

The pots (if present) could be anywhere on the component side. They are typically small and may have a bit of goop on them to prevent them from "drifting".

@e-rev project: 25A @ 13.8v is 345w. Accounting for charger efficiency, that leaves you with around 276w for the batteries. If you can tweak up the voltage a tad to something like 14.5v, it would take less current.

well, the only reason i wanted to parallel, is to have only 1 output. i zipped myself before i had any time to do testing... ive given up, it really really hurt.

BUT. can i connect 2 seperate powersupplies (the ones from hobby city) in parallel or will that cause issues too?
thanks,
ryan (if i could do that, it would be more than enough current needed, for $80)
