Thanks for your reply Felix. I think I may have something else going on with my CR.
My UUT is connected on the high-side of the CR, my scope is powered through an isolation transformer and my USB programmer is also connected, but as soon as I connect the ground of my scope to the (-) side of the CR's voltage output I get an over-current at my DC supply. I tried disconnecting the CR from the USB-powered supply, but it didn't remove the short. The short also goes away when I disconnect the programmer (with scope connected). This short only happens with the CR in the circuit.
Are you aware of a failure mode with the CR that might cause this short condition?
The only CR schematic I could find was in PNG format and is difficult to read. Do you have either a PDF or Eagle version of the schematic available?
