| 257789 | 2004-08-03 01:48:00 | I've misplaced my powerpack for my HP scanjet 3400c. I understand (from the bottom of the scanner) that it requires a 12vDC 1.25A powerpack. The problem is, I don't know where to buy one from. Dick Smith don't have them, as don't Noel Leeming, Harvey Norman, Boise. Any suggestions where to get one? Cheers, Mike. |

| 257790 | 2004-08-03 01:58:00 | dicksmiths have powerpacks that have multiple plug kits with em that fit most connections. These powerpacks also have voltage adjustors and one of those settings will almost certainly be 12vDC dont worry about tha amp rating so long as the pak you buy is rated at at LEAST 1.25A cause if it's rated higher then all that means is it's capable of supplying a higher amperage demand than your scanner will require......amps is the measure of the power requirement of the device. The higher amp rating the more power it will use. A powerpack that will supply MORE than required wont hurt it at all. (Just get the voltage and the DC right !!! ) | drcspy (146) | ||
| 257791 | 2004-08-03 02:00:00 | Jaycarhave a 12v 1.25A plugpack catalogue number MP-3220, it is a switch-mode type, transformerless. The transformer types both from Jaycar and DSE seem to be 1amp, which would probably do though. |

| 257792 | 2004-08-03 02:00:00 | Dick Smith don't have any 12v powerpacks that will supply 1.25A. The most any of their 12v packs offer is 1A which won't be enough. Mike. |

| 257793 | 2004-08-03 02:02:00 | DSE have nothing listed that will handle the current. They have plenty of AC output, and you could build a rectifier and regulator if you are handy with electronics I guess. Jaycar have one listed though. http://www1.jaycar.co.nz MP3031, switchable voltage selection and its regulated. Most are not regulated at that current (regulated is best) $49.00 |

| 257794 | 2004-08-03 02:04:00 | Terry's pick is best, as its cheaper and you don't need the selectable voltage. | godfather (25) | ||
| 257795 | 2004-08-03 02:04:00 | Got a dead Scanjet 3200c here with a working psu. It has a output of 12v,1.0a max 12w. You can have the whole thing cheap if it will help..... |

| 257797 | 2004-08-03 04:31:00 | Or have a look in a Cash Converters shop. They often have a bin of power bricks at $10-$15. Of course with all power bricks there is the problem of the infinite permutations of plugsize/polarity/ac-dc. :_( Although a diode which would prevent disasters must cost about .001 to install, most manufacturers don't install it. Smoke escaping from the equipment is a bad sign. |

Most are not regulated at that current > (regulated is best) > $49.00 I have a feeling (probably wrong) that the switchable voltage affects the ampage in the opposite direction - if set to 3v then 1.25A... if set to 12v then 300mA. Not quite what I want (or am I wrong?) I've emailed Jaycar last week (they're not in Tauranga), but am still waiting on a reply. Mike. |
