Need replacement AC adapter that works with 220V

I posted this message before and got NO REPLIES. Surely I am not the only one who travels outside of the U.S.?

-----------------------------------------------------------------

For some reason the AC/DC adapter for the Linksys router that Vonage sent me does not accept 220V/50Hz input. I need to use this abroad, so I am looking for a replacement AC/DC adapter that works anywhere.

The specs on the AC/DC adapter that came with the router read as follows:

MODEL NO.: D12-1A
INPUT: 120V 60Hz 23W
OUTPUT: 12VDC 1000mA

I am looking at the "Universal AC/DC Adapter 1000ma-SS105" at this link: http://www.dvdoverseas.com/store/index.html?catalog12_0.html

Can anyone tell me if this will work? The specs listed for this adaptor read as follows:

- Switchable 110V and 220V 50/60 HZ
- Output : 1.5, 3, 4.5, 6, 7.5, 9 and 12V DC
- 1000ma max

I do not understand why different voltages are listed for the output. Is there a switch to set it to the voltage I need (12V in my case) or what?

Or can someone recommend a different AC/DC adaptor that would work with this router?

Thanks for any help on this. (It sure would be nice if Vonage would use equipment that works worldwide and save us this hassle. I thought it was almost unheard of in this day and age for computer

The "universal" power supply you're looking at is meant to be able to satisfy the most common voltage requirements, so yes, it has a switch that you must set for what is required, in this case 12v. In the States, Radio Shack usually carries such a supply, however not with the 220V capability. Usually these types also have a mess of connectors at the other end, one of which is supposed to match what you need. For example, sometimes the center conductor is + and sometimes it is -, so you need to get this right! Also, if you set the output (or input) voltage wrong, you could theoretically damage your unit. The probable difficulty will be the connector, whether the supplied ones fill what you need. But otherwise, it ought to work.

In the UK, it is very easy to find a 220/240V to 110V AC Transformer, just look for a T2 store (Formerly owned by Tandy/Radio Shack),
Here's one: £6 (≈$11.19) + Shipping

In Europe a 220v to 110V AC step down transformer with US socket to local plug are easier to find than an adapter to step up 110V to 220/240V is to find here, no matter which country you are in, just look for an electronics store, they might stock one or tell you of someone who does.

PS. My PAP2 came with a dual voltage AC/DC adapter, all I have to do is either obtain the sleeve with a UK or other countries plug or a plain and simple US to local plug adapter.

I solved the 220V problem (for about $50) but went a different route that also gives me flexibility for the future.

Linksys 12 Volt Power Over Ethernet Adapter Kit

The Linksys 12 Volt Power Over Ethernet Adapter Kit is 110V/220V and removes the need for a power outlet at the unit. Instead, you use a power outlet near the DSL modem and the power is injected into the Cat 5 cable, then split back out and plugged in at the unit. Works like a charm and I don't need the supplied 110V adapter anymore.

Grog,

Your solution sounds very good. One question, where did you connect the adapter before connecting it to the rt31p2? It says in the details that it needs a PoE port so that it can deliver both power and data. Is that PoE port from your cable modem? Just wondering,

On page nine of the User Guide, there's a sketch of the configuration.

In my case, the 'workgroup switch' that they show is really a Linksys router which then connects to a DSL modem. For you, it might only be a DSL modem. (I've got: DSL modem->Linksys router->RT31P2. You might not have that extra router).

I've found a source for exactly what we need to resolve the 110-220 frustration! They're normal power supplies with US plugs, that can take any worldwide current with only an adapter. No Radio Shack junk needed (with my apologies to Radio Shack, et. al.)

The only thing that I needs to be done on these is to change out a couple of components to give output of 12v, 60hz, 1A, 23 W. It's not a tough swap, but should be done by a pro.

I'm thinking of starting a business -- though this is obviously a fairly small market Very Happy

bart, thank you for your post in finding a solution. However, for the rest of us, there is absolutely no reference to an URL or product that it is very difficult to make heads or tails out of your post. Would you please give some details (i.e. model #, brand, etc). And what exactly are you swapping?

I apologize for the confusion -- I'll try to clarify:

"They're normal power supplies with US plugs, that can take any worldwide current with only an adapter."
-- Not much else I can say there.

"The only thing that I needs to be done on these is to change out a couple of components to give output of 12v, 60hz, 1A, 23 W."
-- The power adapters (originally manufactured to provide 15v output) can be easily modified by a qualified technician. The result is a replacement power supply which fits the specs for the RT31P2 and can be used anywhere across the range of worldwide voltages.

"Swapping" was with reference to the components that need to be swapped out in order to make the conversion.

These are not for sale on a site, so there is no URL to give. I found them through a personal contact.

Once again, I'm sorry I wasn't clear, but my intention was really more 'tongue-in-cheek' that I had found a resolution for the voltage/portability issue. Hope that helps -- and I'm happy to be of any further assistance I can.

I mentioned itin one other thread once, but I don't think a response was given..

What do the vonage.uk customers get to power their ATA's in Europe?? they obviously have something that works, is it not possible to get ahold of the power supply that they are using?? I imagine Linksys has them.. maybe I'm wrong Question
