dc-dc convertor

[www.recumbents.com]

Hi Guys,

I'm getting tired of replacing batteries in lights, soI want to power the LEDS with my ~48V e-bike battery. After poking around for a while I found this:

http://www.trcelectronics.com/Cosel/sus34805b.shtml

It converts 36-72VDC to 5 VDC, 3W max.

I should be able to hook that up to an LED driver to provide the required lighting. The only issue is that it says "we only sell to businesses". Do I ignore that and just order it, is there a better supplier, or another product that does the same thing?

Thanks,

-Warren.

A few of us have been using these for about a year now with no problem. Highly recommend them.

Agreed. They run cool, whereas another dc-dc converter I used melted the trunk bag in which it was stored. The Hitrons can power a magicshine/p7 either off the 6v 3A or the 12v 1A without much complaint

Look at (SCOOTER SUPPORT.COM) thay have a good dc-dc 36volt-48volt 10amp (120 watts) for $24.oo plus shipping, these are good convertors and I have about 6 of them. It's listed under the electrical parts section.

I've posted this link before:

It looks like they have labeled the wires now, so no guesswork. Only converts to 12V however.

Thanks guys, the Hitron converter looks like the ticket! I just ordered a couple.

I have lost two tail lights already because they take a pounding and vibrate loose and at 30MPH you can't hear them fall off. Because this has 3 output voltages I have a choice of what to use, and 30 watts means I can power front and rear lights with the same converter.

Thanks again!

yes good call, i ordered 4 of them a week ago, they arrived today and no customs charges either as the value as under 18 dollars and that was without adjusting the value to get it to slip through.

Be a shame when they are all gone! thats why I got 4 of them.

Damn, no more left. And can't find anything with approximately equivalent specs eBay. Only a 8v 1a one, a bit too weak for a Magicshine.

I wonder if that one would work. Outputs 12v 1500ma. Does Magicshine self-regulate the current? Otherwise I'd always be feeding it 18w which I believe is its max power handling. Dunno if that's a good idea.
