    Hi All,

    We Have a CTouch 3 that we need to install, the problem is due to the Building type (Concrete) and lack of space we can't use the version 3 power supply for this.

    Is there anyway to convert the ver 2 power supply to work with the new Touch screen? We will then be able to run the long lead back to a point where we can give power to the unit.

    Thanks in advance for any input

    The answer is no... The V2 power supply will not work with the V3 touchscreen. V2 touchscreens use 5V (needs to be very accurate voltage) and hence have a small regulator that is very close to the touchscreen. V3 uses 24Vdc and is much more tolerant to voltages outside spec. We chose this voltage to make it much easier to provide a lower cost power supply whilst allowing for volt-drop (hence the over-rated power supply).

    As Rooster has mentioned in another post, use the cable from the V2 power supply and feed the 24V down it to your touchscreen. Observe the polarity but other than that, all should be good!
