Power supply for scanner.

  jack 13:41 16 Dec 2007

In resurrecting an older scanner my chum found that the 15v power 'brick' had failed.
So he found a universal supply that delivers up to 12v.
This worked up to a point but the scan is iffy and the colour off.

Rummaging in my 'Bitza Box' I cam across a brick that delivers 16v.

So the question now is - 'Is it possible that scanner will have a +1v tolerance or will it be Toast?

Depends how much value you put on the scanner. If you are trying to rescue it from oblivion, then it's worth a try. If it doesn't work you haven't lost anything.

If it does work you have a potentially useful piece of equipment.

It's doubtful that 1 volt overvoltage will cause much problem. There will normally be a protective circuit in the scanner itself to take care of small blips.

You had also better check that it is correct as to the output being the correct sort of low voltage, AC or DC wise.

He has it now so wish him luck.
WizKing- power adaptors for this type of equipment are always to my knowledge step down transformers 220vAC to low volts DC
I am not aware of any other sort
The ones in question certainly are AC220 to DC 15 in the original and 16v 900Ma in the replacement.

it should work, check amps on old and the one you want to use

We can mark this one up as a success
the Scanner seems quite happy with the 16v brick.

Some bricks ARE AC output. I have a few (things like Christmas trees can use AC ) so always check it.
In addition check the polarity, ie center pin + or -
Lots of equipment have low tolerance supply requirements.
