As most other device entities in SeqZap, the AC Power Supply entity also has a device entity panel.
The panel is shown by selecting a PSU entity in the device browser panel.
When the panel is initially shown it will refresh the state of the PSU, this is equivalent to pressing the Update button.
While the panel is updating the user-interface is disabled and cannot be used.
Figure 2 AC Power Supply entity in with output disabled
When the PSU is OFF (output is disabled) the Voltage value shows the configured voltage level – after the PSU is turned ON (output is enabled) the Voltage value shows the voltage level measured by the PSU.
Please note that the values shown in the panel is not updated automatically or refreshed periodically, to retrieve the current state of the power supply, the Update button must be pressed.
