Power supply 12v step up to 24v help needed please

[Souskei]

Hello!!

I have this power supply
http://www.commonsenserc.com/product...roducts_id=765

And the hyperion 1410i net3 charger.

I wanna use all the power the Hyperion charger has to offer, but the PS only outputs 12v.

My question is, is there any way to step up the voltage coming out of this power supply to 24 volts? And still have the 42a 500 watt output?

I know I could just buy another one and wire them in series, but step ups are cheap and are readily available at electronic stores.

Oh..
And if I wanted to add an on/off switch somewhere.. Where would I wire it?
Jus inline from the ac leads?

I don't think it is possible unless you cut your amps in half... and I'm not sure how you could even do that. You could use 2 deep cycle batteries in series that's what I do.. I spent $70 for each and can field charge all day long.

I'm ok with the amps cut in half..
My charger is only a 20 amp output..

I would recommend that you check in the Hyperion manual or other source to find out what the minimum voltage is to allow the charger to reach its maximum output for the cell count of pack you are using. Most likely it actually something less than 24v. Maybe closer to 18v. Your power supply has a voltage adjustment knob and can likely be turned up beyond 12v getting closer to the chargers max output.

Though high current DC to DC converters exist, they are expensive and will cause another 10% drop in power efficiency. The DC-DC coverters we use for hobby purposes at best have a 10% loss. There are currently two DC-DC converters already in the chain, one in the power supply and one in the charger. Best case scenario, adding another converter is going to reduce your output down to approximately 400 watts, or 16 amps on 6s packs.

I did a quick search in ebay and the cheapest 12v to 24v 500 watt converter I could find was $80. For that price you could buy a 24v server supply setup. That way you would not have addition power losses, have a power supply that is power factor corrected and be set to go for your next charger.

One thing that bothers me greatly is that Hyperion does not publish nor make it easy to locate the specs and *complete* manuals for thier chargers. On a fairly regular basis I and others help folks on this and other forums by reviewing a charger's manual and providing spec interpretation and guidance. By limiting public documention and specs, Hyperion has choosen to make it more difficult for the customer base to support each other. Kudos to FMA/Revolectrix, and iCharger for making complete and detailed manuals.

Thanks for the info Greg!!

I'll try adjusting the knob and hit it with a volt meter to see where I'm at.

The cheap "step-ups" are transformers, and wont work at all with DC. Only real option is to use a 24V PS.
