In Reply to: power supply for image scanner posted by Jeff Bates on 01/26/00 at 10:57 PM:

: I have an INFO computer image scanner and I have no power cord for it. It's rated at 12 volts, 1 A. I have 12 volt AC power adapters but they are all rated at 300mA. What's the difference between mA and A? And will a 12 volt AC power supply at 300mA burn my scanner? I'd really appreciate your help. Jeff

Hi, Jeff:

The 300 mA rating means 300 milliamperes which equals 0.3 Amperes. That is too light for the 1A or 1 Ampere requirement. It won't deliver enough current to operate the scanner. You need more current than the 300 mA unit can provide.

Good luck.
