Thanks again VK6KRO,
Yes, +12V output for HV enable and -12V output for HV inhibit (off) would work. The output lead with these enable or inhibit signals would feed via a BNC connector directly into the back of my multichannel analyzer, which apparently has internal circuitry to switch the HV...
Hi VK6KRO,
Thanks much for the explanation! I believe I am now starting to understand the circuit.
The purpose of the circuit for my application is to shut down the HV supply to the HPGe detector if the temperature warms above about -160 deg C. Lower than this temperature (thermistor...
Hi all,
I am hoping that someone here on the Forum can provide this chemist with some electronics assistance :biggrin: .
I am working on setting up my newly acquired HPGe detector with my MCA system
The only thing I am missing is a HV bias supply shutdown in the event of a detector warm...
