I want to learn a little about PSUs transfomers can anyone point me to
some links which could prove useful. The reason I ask is that I have
purchased a ADSL router on eBay recently and I think that the PSU may
be not be suitable/not the original one. It is a Netopia 3341,if
anyone is familiar with it. I have seen and fitted a number of these
routers and they usually are supplied with laptop type power brick PSU
- this one is not. This is not what concerns me. The router has an
input of 12VDC, 1.0A (labelled on the underside of the device) and the
PSU is labelled as:full label is Input 230V ~50Hz 140mA, Output
10V-1.2A.

Is this correct and safe to use or could I damage the router. Do you
think that this was indeed the PSU which was supplied by the
manufacturer. I would have expected output to be 10V. Please advise
and explain so that I may learn something and put my fears to rest.

Any help and advice greatly appreciated.

In all probability (99.99% or so) your router doesn't actually require 12V. It's
likely that the manufacturer specified 12V because it was convenient to obtain
power bricks of that voltage.

I can't see any way you can harm it by using the 10V brick to be honest. It's
likely to run cooler in fact which is no bad thing.

Thanks for the advice Graham

Actually, I had noticed it ran cool - both the PSU and router - it is
working i just want to make sure this is okay.
