Power Supply for all the "gismos" ?

[Czechmarty]

Hello guys.
I'm trying to figure out how to get rid of all those little power supplies powering all my stuff.
Here is the partial list:

Netgear FS108 switch 12V/1.2A
Ocelot 9-12V/1A
SECU16IR 9-16/200mA
ELK800 amplifier 12-24V/50-800mA
W800 receiver 7-12V/20mA
KVM iView switch 9V/?mA
+ few cameras in future.

I saw these ELK devices:

Here is one of them on Martin's WEB site:

But they are rated max 2.3A.
SO I was wondering if I can use old computer power supply, because I have around 3-4 of the old AT type and one ATX type just lying around.
Would that be OK? Would I need any additional circuits?

Thanks

Marty

I don't see why not as long as each device has a common power requirement (e.g. 12VDC). Obviously you would want to ensure your hardware is either AC or DC.

Marty. I use the power supply that runs my HS server to power most of my support devices. I bought a disk drive power splitter cable from the local computer shop, used a multimeter to determine the voltages and the polarities. I then looked on the back of all the devices to determine the polarities of the plugs and the sizes required, used a bank of terminal strips and wired each plug to it. I also use the 5vdc output from the computer to power the analog inputs for the TC+.
With the HS box on a UPS, support devices stay up as long as the battery lasts. Just watch the polarities and overall load and it should work fine.
I did have a case where two devices used the same size plug and were wired reversed from each other. I once plugged the wrong one into the wrong device. The power supply on the computer shut down immediatly. I cursed, restarted the computer and all was fine. After labeling the leads the system has worked fine since.
There is some thing about having to load the output of a power supply from a computer if it is not connected to the motherboard. There are many articles in the Radio Control modeling forums about doing this. The electric modelers use old cpu power supplies to charge their batteries.

Thanks for the replies guys.
I might give it a shot and play with it over the weekend. (Unless something will show up on my HoneyDo list..... )

Try looking at Altronix gear (readily available from Ebay). It's geared towards alarm and camera use and is industrial strength. I use a couple of them to power all my stuff and they can be hooked to inexpensive batteries to provice power backup. They even have relays that designate if they have AC power or not.

From Ebay: With enclosure and fused power distribution

From Ebay: Just the Power supply

Altronix web site has good docs on all their products: www.altronix.com

Thanks Paul!
They do not look bad at all. I might consider this option as well. I'll see what will be the price at the end of the auction.

I have 2 of these, they're great: http://www.partsexpress.com/pe/showd...number=120-536

They also have an assortment of power supplies of all volt and amp ratings here: http://www.partsexpress.com/webpage....ctGroup_ID=427
