I have a customer testing out a VC5090 for use inside of a crane, but the crane runs 250 volts which is too much for the VC5090 to handle.  I am being told that they will need a DC to DC Converter with 250VDC input, and an output of anywhere between 12-48V (and large enough to support at least 60W. I can not find a converter like this anywhere on the web.  Any suggestions? Thanks, Adam 610-608-1191
