Do you have different regulations perhaps? Around here, 48V is about as high as you can go before safety regulations start getting in the way. Between that and the fact that it is/was a common telco voltage (possibly for the same max voltage versus saftey tradeoff), 48V is a common off the shelf power supply voltage. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
