2700HG adapter plug voltage

[jimconsole]

Hi,

ive just been put on an adsl2+ service and the day after my 2700  power adapter died 

Just tested the router with another adapter and it works , so router is fine. Wondered can i use a multi voltage adapter in the meantime?    the router takes 5v    but my multi voltage adapter nearest v is only  4.5v  or 6v

Apart from waiting for an replacement adapter, which voltage setting could i use in the meantime?

Thanks

Maplin have a 5V supply for £8.99.

Hi

Thanks for replying.

The thing is i have no dosh until friday and currently using a friends internet connection, when i get home later i need the internet and really wanted to find what was the best way to go about it in the meantime using 4.5v or 6v?

[Rik]

I'd go for 4.5V, it's less likely to damage the router.

[jimconsole]

Ok thanks Rik i'll see how it runs

I agree with Rik. I certainly wouldn't want to put more voltage through than the normal adapter, but less shouldn't do too much damage.

Maplin have a 5V supply for £8.99.

I took a look Rik and the 5V one Maplin have is only rated for 2.5 Amps (DC 5 V 2500mA)

The 2700 PSU is 5.1V at 3.5A as supplied with my router.

I don't know if it needs such a high current as 3.5 A but a 2.5A one might be a bit light on umph! 

(In a word or three of caution over-heat if used continuously)

[Rik]

Thanks, Les, I didn't look at my PSU to check the rating.

Make sure you use a REGULATED ADAPTER  do not under any circumstances use an unregulated one   

it should be rated at 5V 3amp or higher the amperage that is not the voltage do not stick 6Volts into it.

maplin also do one for £20 that does 5V at ithink 6 amp. Also ensure you get the polarity on the plug correct or bye bye router (possibly).

Good tips.

I have just picked up this PSU on eBay for my second (Spare) Dual SSID 2700HGV.

Its not a 2Wire one but at 3.8 A, provided it is regulated and I am given to understand that it is, I think it should be OK. 

What say you guys? 

Notice I kept this "tip" to myself until the auction ended. I did not want too much competition pushing up the price.

As they say Les. "nothing personal, just business"

As you say Ted. 

The item in question arrived today and it works just fine. In answer to a question the seller told me it was "new and tested". Well for new it is a wee bit jaded but since it works I am not concerned that the pristine look has faded. 

To check it out I had a rummage in my garage for some low Ohmic value, wire-wound, highish wattage resistors and with half a dozen or so in parallel managed a combination that gave me 2.8 Ohms as measured on my Fluke.

With this as a load on the PSU the open circuit (no-load) Voltage of 5.24 Volts dropped under load to 4.95 Volts. So with Mr Ohm's Law of I=V/R, I calculate that I was drawing 4.95/2.8=1.77 Amps from this PSU. OK not the 3.8 A this PSU is rated at but the most I could muster without going to a lot more trouble. As the volts were holding up OK at this load I gave the guy positive feedback.   

The regular 2Wire PSU that is in service with my no.1 router is rated at 5.1 V 3.0 A but I have not switched off no.1 router to test its PSU in the same way. I bet Dean has a thought or three on this though. Where's Dean?

I finally found a place to buy a DC power plug with a 10mm long by 4mm outer barrel diameter and 1.7mm inner connector diameter to replace the larger barrel plug that was on the power supply when I bought it. The other evening I removed the original plug and soldered the new plug on to the output cable.

After a check with my Fluke to make sure that the DC Voltage was of the correct magnitude and polarity, namely 5 Volts DC with the positive on the inner, 1.7 mm terminal, I connected this power supply to my spare 2Wire 2700HGV Single SSID router and switched on.

I am pleased to report that this unit powers the 2700 just fine.

I did connect the LAN up to my PC and login in to this spare router and took a look at the settings but did not connect it up to my ADSL (telephone) line. Evenings are not a good time for me to resynchronise lest I should get a connection speed that would jeopardise my IP Profile.

If anyone has need for such a power supply the unit I obtained is detailed below and from my perspective adequately powers my 2Wire 2700HGV router in the absence of a genuine 2Wire one.

ITE, AC/DC Adapter, P/No BS05EU, 5 Volt DC - 3.8 Amps

Thanks, Les, that should be useful.
