110AC to DC power converter

[kingofwylietx]

I am looking to find a source for 110AC to DC power converters. Output can be anywhere from 12-28Vdc. My total power requirements are approx 100W continuous duty.

This is for a POS display where all the devices can utiltize 10-30Vdc. We want to be able to plug them into a standard wall outlet, which is why I am looking for the power converters. Right now, I only need a couple of them.

Hopefully size can be kept to a fairly small footprint, but I can work around anything.

Any thoughts?

I'm hoping to find a fairly inexpensive option, as I will be giving these away.

Anyone? I've looked at Tripp Lite, but they are a little bulky. I really need to order them soon, so if anyone knows of a good brand....please advise.

Computer PSU? I can't recall the voltages they put out, but I think 12v is on the list. Xitanium makes purpose-made ones.

i don't know if these 12v 96w Power Supply would be big enough for you as they are only 96 watt but i have used them for some time with no trouble and they are not that big and plug in to a standard US outlet.

I think the 96w unit will work it it can produce 96 watts continuous output. I will be at the edge of it's rating, so it can't be anything but a continuous duty cycle rating at 96 watts. Do you know more specs than what is shown on your webpage?

output is 8.33Amps at 12v it is a switching mode adapter and is made for Information Technology Equipment but i don't know what the duty specks are but we have lots of customers running our 4 of LED Strips that use a total of 8 Amps and in restaurants and bars they are on for 6-12hrs a day and we have not had anyone say they had any trouble.
you are welcome to try one and see if you like it.

Computer power supply is likely to be the cheapest option, especially if you go out and salvage some from used computers, garage sales, thrift stores, used electronics warehouses, etc etc.... You can buy brand new ones online for like $10-20. Since you don't need to hold tight tolerances on the output voltage, the cheapos should be fine.


The 12V output on a typical 300W ATX supply is good for about 150-200W of the total rating, (to use the "full" 300W of the unit requires loading the 5V and 12V outputs near maximum on each).

(oh forgot to mention, you'll have to trick the PS into turning on since it's not hooked up to the mother board. Hint: Green wire to ground on most )

Mdocod, thank you. That is exactly what I need. I didn't even think of pc power supplies. Cheap and easy to find, good call!

I picked up an Antec 350 watt power supply today and hooked it up. It works great and has plenty of capacity, so I am not pushing it. I grounded the green wire, so now the on/off switch built into the power supply is the main switch. Thank you.
