Of course they are. And what happens when two of the home brew supplies touch...same thing... I actually have to stick up for them a little on this one. Good price comparatively to other power supplies. I'm probably going to buy one myself as I dont even seem to have the time to fix my RC's anymore.

read his post - he already said we're not "average Joes"
why do you think they're used?

the cases are NOT touching, they have a thin piece of something between them

most of the power supplies that I have seen have double the output at 240v then they do at 110v

the price of 1 new PS are more than what they are selling both of them for...

The power supplies are brand new.

We will be offering a 1 year warranty on them that will be updated on the site shortly.

Thanks,

Brandon

Personally, floating one of the cases away from ground is NOT the right way to do it. It works, but there is a potential for something internally to go wrong (like a wire coming loose) and make the case float at whatever circuit it is touching. This is why everything with a metal case is grounded. Either that, or you'd have to wrap the internals in something non-conductive and then put that in the metal case, but what's the point in having two cases? Or, remove all the internals and put them in a completely different case with only the more negative supply ground referenced.

To do this "right" with minimal work, you'd decouple the supply output ground from the case altogether (technically, this only needs to be done on one supply), tie both cases together, ground both cases, and to make things more tidy, internally create jumpers of sorts to tie the mains inputs together (just so one power cord is needed).

So you agree with them that they're giving the RC world a bargain!

edit: and now I see that your question about the cases touching was a very good one!

I think Brandon's response was rather good considering the distaste for MA on this board. Bravo for doing what Jason could not do- staying cool.

Consider what BrianG has stated about floating one of the case grounds. You are creating a non compliant power supply with the way that you are constructing them.

Ironman · 10.28.2010, 01:41 PM

is it UL listed?
or even saftey tested?

_paralyzed_ · 10.28.2010, 03:35 PM

I really don't understand the fuss. This will work as good or better than all of maxamp's exemplory products.

+1 to this

One of the biggest rules of representing a company is NEVER, ever, ever, ever argue or antagonize with the customers (or haters, whatever the case may be). You never see any of the Castle, Tekin, or Novak guys doing it, no matter what is said about their products, because they know no good can come of it. Here's hoping MA is jumping on the bandwagon.

JThiessen · 11.02.2010, 06:55 PM

I just bought a pair of these off a guy over on RC-Tech. Paid about the same for them as one from MA. I just dont have the time right now to get my own configured.

Overall the price isn't bad and I would consider buying the 24V version to avoid the hassle of wiring them up properly. Brian pointed out some good things above and I would like to hear from Brandon on the subject, I for one am concerned that one of the cases could end up floating because it's hard to tell how they did it from the pictures.
