    Additional Information: http://ergpower.com/pdf30/DC_DC_Converters.pdf 

    Applications: The voltage needed could be for any number of applications, such as an ink jet printer used for CAD drawings or medical data where each jet needs 40 VDC to operate and that voltage is not in the system; so a DC-DC converter can be installed to convert 12 VDC to 40 VDC for each jet. Other applications that ERG’s DC-DC converters are used for include fuel pumps, test equipment and many others.
