In the case of an engine ECU, you need default values in case a sensor is bad. An oxygen sensor needs time to warm up, so it needs a value to keep the car running. The car runs in a "open loop" condition typically a certain engine temperature is reached.
Some information can be gotten from...
Another idea. I'm just throwing them out at you.
A power OP amp from say Apex Microtechnology or build a high voltage stage for a standard OP amp.
If you need multiple isolated outputs, use custom transformers, but use the primary to indirectly measure the secondary current. Initially, you...
If this thing is a "one of", thing or proof of concept?
Can you use DC?
If you can, look into electronic loads. They can do constant R, I, P, V etc.
Where I worked, the system that was set up before me used Variacs, transformers and phase angle fired dual SCR units to heat 40V tantalum...
This may not work, but it might help solve the problem.

It looks like it tilts and you can also vary the separation. I guess the box is one plate of the capacitor and the brass is the other side.
Separation varies the capacitance. So would a varying dielectric. See...
I modified my response to "I don't think so" Polycarbonate blocks UV. Acrylic transmits UV.
The florescent tube is excited by UV that strikes the phosfors on the tube., e.g. Mercury vapor. In this case the UV stays inside the tube and the outer glass does not let it escape. The visible...
I don;t think so. We had polycarbonate about 12" away from the stray light of our high intensity source of 254nm (Not UV-C) source with no issues. (Modified answer)
