    I'm sure that a generic CPC unit will do the job. All we need to know is:-

    Voltage, Current, connector size and polarity.

    And probably <£5.00

    I couldn't get any from anywhere so I ended up buying them from promethean
    If anyone knows where I can get cheaper ones that will fit, PLEASE let me know!

    The Promethean PSU output 6v and 1.7a. I can't remember if the centre is positive or not. And i can't tell the size of the connector.

    Would you mind mentioning how much they were Witch? Just out of interest. Replacement projector remotes were £75!! Pens have come down quite a bit now, especially if you buy a few.

    CPC code PW00521 is a 6V 2A PSU with a range of connector sizes, £13.11 ex VAT. Page 1600 of the dead tree catalogue.

    The relatively high current and 6 rather than 12 volt pushes the cost up.

    this is very close to the psus for Activboards (same company, unbranded etc), but don't order it because the output voltage is too high and the amps are off too, but it's a good example because these are £20 without packaging. Ours are £25+£5 P&P. That's not bad when you compare to some companies.

    ... and two posts up, I link to one with enough current and not too many volts, and it's cheaper too!

    up to you, I know how sensitive the chips on our electronics are, and I wouldnt risk it. definately not with a board that's in warranty. if it's in warranty and we see another kind of psu dangling from the system during a repair then there may be a hefty bill involved.

    Re: replacement power supplies for promethean boards

    I'm with Andrew_C : I've used the 6V 2A £13 PSU's from CPC and there fine.
    (actually I tested it on a board that was in warranty - just to be sure
    A 2A PSU is rated to be able to provide 2 Amps - if the board only draws 1.8 amp then it's not going to force 2A on it!. Just another over hiked price from promethean.
