Rail Setpoint

The PS2-08-A power supply has an internal high voltage (HV) rail that can be adjusted by the user. This voltage is the maximum voltage that the power supply can output, however, the actual output voltage on each channel is regulated by the device via feedback control.

It is highly recommended to keep the rail voltage between 1500 and 10000 V. We recommend setting the rail voltage at or slightly higher than the maximum voltage required for your application.

ARDI can be used to facilitate setting the rail voltage using the built-in potentiometer. To do so, first run ARDI in interactive mode:

python -i -m ardi

Then, run the following command:

rail.echo('v_mon')

This will continuously query and output the rail voltage in volts to the terminal in real-time. Note that it will be zero with HV off. Now, turn the HV on, and adjust the potentiometer until the desired voltage is reached. Press Ctrl+C to stop the output to the terminal.
