No, had no much luck. I think I'll go triax for sensitive stuff anyway as 2nd choice.
Tested HV DC-DC module, working like a charm. Love adjustment option, would be easy too use as coarse adjustment output voltage.
Here are some testlog photos for your enjoyment..
Forgive crude setup, don't any good HV caps at moment to decouple output. Just proof of concept test.
Keithley 2400 (in center top): +12V power to UltraVolt 1A12-P4-F-M DC-DC module
Left Keithley 2001: Output voltage measure
Right Keithley 2001: Remote Adjust Input measure. This voltage sourced from
EDC MV106 DC Standard
Keithley 2002 (in center bottom): +5VDC Reference Output from UltraVolt
Here are check points at 100V, 200V and 1000VDC
Also checked with Fluke 87V. Little meter spot-on agree to K2001, and measures only up to 1090.4VDC, after that just gives OL.
I don't have anything ready for 6KV DC-DC module, so will test that one later.
Wish I'd have negative supply as well. Eh, one thing at a time, will come to that later.
Now time to go back to low-voltage stuff on control side..
