  • 24-Volt Opus DCX3.120P - convert to 12v?

    Here's hoping that someone out there knows these 120w PSU's inside out!

    I have several Opus "Vehicle PC" units (see my post in Classifieds forum: Opus Solutions "Vehicle PC" Mini-ITX system including Power Supply, case (NY USA) )

    These units have the Opus DCX3.120P PSU, but these were made for diesel buses with 24v systems.

    Apparently, back when Opus made the .120P, you ordered either 12v or 24v. DCX3-120P_Quick_Guide.pdf

    The newer versions of this board (.120RevE) have a jumper to select 12v or 24v input (very convenient!) DCX3-120-revE Quick Guide.pdf

    Does anyone have a clue how these could be converted from 24v input to 12v input?
