Well, it's for monitoring. Here's the deal. I am building a HV power supply for a CO2 gas laser. The Plasma cavity is 24" long. I need the power supply to monitor the voltage across the cavity, the current through the cavity, and the voltage and current before the HV transformer. Obviously...
I am trying to avoid resistive because of a noise issue, I tried a resistive ammeter and it fluttered between 1ma and 5ma, I need something more reliable and less jumpy
I am in the process of building a High Voltage power supply for a CO2 laser, it's 15KV current limited @ 30ma. I need a circuit that will monitor the voltage and current of the output across the discharge tube. Remember this circuit must handle HV without letting the magic smoke out of the...
