Here are our two new power supplies:

http://www.maxamps.com/Power-Supply-12V.htm

Specs
* 100v-240v AC Input Voltage
* 12.15v DC Output Voltage
* 47A Continuous Output Current
* 575W Output
* 11" x 2.25" x 3.125" dimensions
* 3.25 lbs
* Short circuit and over-voltage protection
* Heavy duty metal cabinet

http://www.maxamps.com/Power-Supply-24V.htm

Specs
* 100v-240v AC Input Voltage
* 24.3v DC Output Voltage
* 47A Continuous Output Current
* 1150W Output
* 11" x 4.5" x 3.125" dimensions
* 6.5 lbs
* Short circuit and over-voltage protection
* Heavy duty metal cabinet

Both power supplies will charge at 47 amps all day long. A number of us have tested these and I know the guys at Big Squid RC have been using the power supplies with great results. Were talking about running two chargers each at 20 amps.

Regarding some of your comments:
One of the first things I wanted to do at maxamps.com was come out with an affordable power supply. I come from the computer industry and before that the electronics industry before I ever worked in RC. Day 1 at maxamps.com I started looking for power supply distributors and an affordable way for the general guy to be able to power his chargers and other devices at a rock solid price. I myself have built computer based power supplies and used them a number of times in the past for a number of uses.

We are not hiding that these are made from computer power supplies. We went that route because they are more affordable for average Joe. Right now it costs around $125- $160 for a good 20 amp power supply. Unfortunately this is only good for one high-end charger. There is a need now for more power with the latest Hyperion and FMA charges, among others that will follow suit shortly.

These power supplies are an incredible value for a quality product. MaxAmps.com are getting a really good quality power supply then we are modifying them ourselves at our shop. These supplies are wired correctly by electronic experts and are voltage checked for proper polarity and correct grounds.

We as a company cannot recommend to anyone doing these mods yourself. Modifying power supplies is dangerous and is something the average Joe should not be doing. If you guys mod them and they work that is fantastic. You are not the average Joe.

These power supplies are an affordable way to get the standard RC charging at a good rate with peace of mind that he just plugs in it and goes. No modifying. No worrying about shocking yourself. No worrying about ungrounded circuits.

A couple of you are posting some comments regarding legal issues and copying and things of that nature. There are a million computer supply mods out there and I have read a number of them. I believe this one actually exists on a number of sites as it's a popular server power supply. We did not steal anyone's idea and were not ripping off anyone's mod. We have the spec sheet from the manufacturer and we modify these power supplies to be both safe and easy to use.

Thanks and if you have any questions for me please let me know. Just understand that I am busy and trying to get done a lot this week. Wow that was a much longer post then I anticipated. Cheers

Brandon

im glad you picked up where jason left off, i cant wait till next year when you guys invent brushless motors

what happens when the cases touch???

why are you not advertising the 100ish amps that they can put out?? it seems to fit with the other MA products....

WE, are not "average Joe's" even though an average joe could get a server PS to work, all you need is a pc jumper and wire to solder to the contacts....

what happens when one of these already USED power supplies fail???

IRRC the price on new server PSs are more than what they are selling them for...

also, according to MA, if you have an alloy cased charger, if it touchs the PS everything goes boom...

hell, I have all of my chargers stacked on my server PS...

EDIT: I did have jason on the first time, but I waited 10min with no response....

zach : Question
new power supply

Clint Preston : Welcome to MaxAmps.com live help. I'll do my best to assist you.
Clint Preston : Yes
zach : hello??
Clint Preston : Yes?
zach : what happens when the 2 cases on your new 24v power supply touch?
Clint Preston : They don't touch. We have insulating tape and Kapton tape between the two creating a barrier.
zach : what if something like a hex driver crosses the back/front case for a sec.
Clint Preston : I just checked with our tech support. They mentioned that yes that would cause a spark so not to do that.

zach : so you are selling a product that could easily start a fire if bumped?
Clint Preston : Basically, just like a metal cased charger can't touch the power supply it is connected to with shorting. Just be careful when using conductive items together.
zach : I do not know of any chargers that use the case as a ground, 99% of them have the boards insulated from the case... the only ones that I can think of that would are the elcheapo generics that HK sells...
Clint Preston : If you need further info on this, I would suggest calling in and speaking with our Tech department.
zach : 1 more question, why are you not advertising the 100ish amps that they will put out when hooked to 240vac, it seems a little more MAish if they were...
Clint Preston : Again, sorry but...If you need further info on this, I would suggest calling in and speaking with our Tech department.

Clint Preston : nullstring

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.

Um:
the cases are already touching and it's obviously OK
why are they not advertising 100 amps? because they are 47A supplies
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...
